Management Access Overview
SNMP Access
Protocols
Scope
The NETGEAR 7300S Series Layer 3 Managed Switch software has two purposes:
•
Assist attached hardware in switching frames, based on Layer 2 or 3 information contained in
the frames.
•
Provide a complete switch management portfolio for the network administrator.
Switch Management Overview
Fast Ethernet (FEN) and Gigabit Ethernet (GEN) switching continues to evolve from high-end
backbone applications to desktop switching applications. The price of the technology continues to
decline, while performance and feature sets continue to improve. Devices that are capable of
switching Layers 2, 3, and 4 are increasingly in demand. The NETGEAR 7300S Series Layer 3
Managed Switch provides a flexible solution to these ever-increasing needs.
The NETGEAR 7300S Series Layer 3 Managed Switch provides the network administrator with a
set of comprehensive management functions for managing both the FSM7328S, FSM7352S and
the network. The network administrator has a choice of three easy-to-use management methods:
•
•
Web-based
VT100 interface
Note: The maximum number of configuration file command lines is 2000.

Simple Network Protocol Management (SNMP)
Each management method enables the network administrator to configure, manage, and control
the managed switch locally or remotely using in-band or out-of-band mechanisms. Management is
standards-based, with configuration parameters and a private MIB providing control for functions
not completely specified in the MIBs.

Administration Console Interface
The administration console is an internal, character-oriented, VT-100/ANSI command-driven user
interface for performing management activities. Using this method, you can view the
administration console from a terminal, PC, Apple Macintosh, or UNIX workstation connected to
Figure 3-1: Administration Console Management Method
Set Up Your Switch Using Direct Console Access
The direct access management method is required when you initially set up your switch.
Thereafter, the convenience and additional features of the Web management access method make
more information.
Direct access to the switch console is achieved by connecting the switch’s console port to a
VT-100 or compatible terminal or to a PC, Apple Macintosh, or UNIX workstation equipped with
a terminal-emulation program. This connection is made using the null-modem cable supplied with
the switch.

Parameters
Parameters are order dependent.
The text in bold italics should be replaced with a name or number. To use spaces as part of a name
parameter, enclose it in double quotes like this: "System Name with Spaces".
Parameters may be mandatory values, optional values, choices, or a combination.
–
<parameter>. The <> angle brackets indicate that a mandatory parameter must be entered
in place of the brackets and text inside them.
–
[parameter]. The [] square brackets indicate that an optional parameter may be entered in
place of the brackets and text inside them.
–
–
choice1 | choice2. The | indicates that only one of the parameters should be entered.
The {} curly braces indicate that a parameter must be chosen from the list of choices.
Values
ipaddr
This parameter is a valid IP address, made up of four decimal
bytes ranging from 0 to 255. The default for all IP parameters
consists of zeros (that is, 0.0.0.1). The interface IP address of
0.0.0.0 is invalid. In some cases, the IP address can also be
entered as a 32-bit number.
macaddr
areaid
The MAC address format is six hexadecimal numbers separated
by colons, for example 00:06:29:32:81:40.
Area IDs may be entered in dotted-decimal notation (for example,
0.0.0.1). An area ID of 0.0.0.0 is reserved for the backbone. Area
IDs have the same form as IP addresses, but are distinct from IP
addresses. The IP network number of the sub-netted network may
be used for the area ID.
routerid
slot/port
The value of <router id> must be entered in 4-digit dotted-deci-
mal notation (for example, 0.0.0.1). A router ID of 0.0.0.0 is
invalid.
This parameter denotes a valid slot number and a valid port num-
ber. For example, 0/1 represents slot number 0 and port number 1.
The <slot/port> field is composed of a valid slot number and a
valid port number separated by a forward slash (/).

logical slot/port
This parameter denotes a logical slot number and logical port
number assigned. This is applicable in the case of a port-channel
(LAG). The operator can use the logical slot number and the logi-
cal port number to configure the port-channel.
Conventions
Network addresses are used to define a link to a remote host, workstation or network. Network
addresses are shown using the following syntax:

Format
Range
A.B.C.D
0.0.0.0 to 255.255.255.255
(decimal)
YY:YY:YY:YY:YY:YY
hexidecimal digit pairs
macaddr
Double quotation marks such as "System Name with Spaces" set off user defined strings. If the
operator wishes to use spaces as part of a name parameter then it must be enclosed in double
quotation marks.
Empty strings (““) are not valid user defined strings.
Command completion finishes spelling the command when enough letters of a command are typed
to uniquely identify the command word. The command may be executed by typing <enter>
(command abbreviation) or the command word may be completed by typing the <tab> or <space
bar> (command completion).
The value 'Err' designates that the requested value was not internally accessible. This should never
happen and indicates that there is a case in the software that is not handled correctly.
The value of '-----' designates that the value is unknown.

Annotations
The CLI allows the user to type single-line annotations at the command prompt for use when
writing test or configuration scripts and for better readability. The exclamation point (‘!’) character
flags the beginning of a comment. The comment flag character can begin a word anywhere on the
command line and all input following this character is ignored. Any command line that begins
with the character ‘!’ is recognized as a comment line and ignored by the parser.
Some examples are provided below:

Quick Start up
The CLI Quick Start up details procedures to quickly become acquainted with the 7300S Series L3
Switch.
Quick Starting the Switch
1. Read the device Installation Guide for the connectivity procedure. In-band connectivity allows
access to the 7300S Series L3 Switch locally or from a remote workstation. The device must
be configured with IP information (IP address, subnet mask, and default gateway).
2. Turn the Power ON.
3. Allow the device to load the software until the login prompt appears. The device initial state is
called the default mode.
4. When the prompt asks for operator login, execute the following steps:
•
•
Type the word admin in the login area. Since a number of the Quick Setup commands
require administrator account rights, NETGEAR suggests logging into an administrator
account.
Enter the password you have defined or simply press the enter key if it is the first time you
are logging in.
•
•
•
•
•
Press the enter key two times.
The CLI User EXEC prompt will be displayed.
Use “enable” to switch to the Privileged EXEC mode from User EXEC.
Use “configure” to switch to the Global Config mode from Privileged EXEC.
Use “exit” to return to the previous mode.

Access to all commands in the Privileged Exec mode and below are restricted through a password.
Mode-based Command Hierarchy
The CLI is divided into various modes. The Commands in one mode are not available until the
operator switches to that particular mode, with the exception of the User Exec mode commands.
The User Exec mode commands may also be executed in the Privileged Exec mode.
The commands available to the operator at any point in time depend upon the mode. Entering a
question mark (?) at the CLI prompt, displays a list of the available commands and descriptions of
the commands.
The CLI provides the following modes:
User Exec Mode
When the operator logs into the CLI, the User Exec mode is the
initial mode. The User Exec mode contains a limited set of com-
mands. The command prompt shown at this level is:
Command Prompt: $(Exec)>
Privileged Exec Mode
To have access to the full suite of commands, the operator must
enter the Privileged Exec mode. The Privileged Exec mode
requires password authentication. From Privileged Exec mode,
the operator can issue any Exec command or enter the Global
Configuration mode. The command prompt shown at this level is:
Command Prompt: $(Exec)#
Global Config Mode
This mode permits the operator to make modifications to the run-
ning configuration. General setup commands are grouped in this
mode. From the Global Configuration mode, the operator can
enter the System Configuration mode, the Physical Port config,
the Interface Configuration mode, or the Protocol Specific modes
specified below. The command prompt at this level is:
Command Prompt: $(Config)#
From the Global Config mode, the operator may enter the following config modes:
VLAN Mode
This mode groups all the commands pertaining to VLANs. The
command prompt shown at this level is:
Command Prompt: $(VLAN)#
Interface Config Mode
Many features are enabled for a particular interface. The Interface
commands enable or modify the operation of an interface.

In this mode, a physical port is set up for a specific logical con-
nection operation. The Interface Config mode provides access to
the router interface configuration commands. The command
prompt at this level is:
Command Prompt: $(Interface <slot/port>)#
The resulting prompt for the interface configuration command
entered in the Global Configuration mode is shown below:
$(Config)# interface 2/1
$(Interface 2/1)#
Line Config Mode
This mode allows the operator to configure the console interface.
The operator may configure the interface from the directly con-
nected console or the virtual terminal used with Telnet. The com-
mand prompt at this level is:
Command Prompt: $(Line)#
Policy Map Mode
Policy Class Mode
Class Map Mode
Use the policy-map command to access the QoS policy map con-
figuration mode to configure the QoS policy map.
$(Config)# policy-map
Command Prompt: $(Config policy-map)#
Use the "class" command to access the QoS policy- classmap
mode to configure the QoS policy map.
$(Config-policy-map)# class
Command Prompt: $(Config - policy-classmap)#
This mode consists of class creation/deletion and matching com-
mands. The class match commands specify layer 2, layer 3 and
general match criteria. Use the class-map commands to access the
QoS class map configuration mode to configure QoS class maps.
$(Config)# class map
Command Prompt: $(Config - class)#
Router Config RIP Mode
In this mode, the operator is allowed to access the router RIP con-
figuration commands. The command prompt at this level is:
$(Config)# router rip
Command Prompt: $(Config-router)#
DHCP Pool Configuration Mode Use the ip dhcp pool <pool-name> command to access the
DHCP Pool Config Mode.

Flow of Operation
This section captures the flow of operation for the CLI:
1. The operator logs into the CLI session and enters the User Exec mode. In the User Exec mode
the $(exec)> prompt is displayed on the screen.
The parsing process is initiated whenever the operator types a command and presses <ENTER>.
The command tree is searched for the command of interest. If the command is not found, the
output message indicates where the offending entry begins. For instance, command node A has the
command "show arp brief"but the operator attempts to execute the command "show arpp
brief"then the output message would be $(exec)> show arpp brief^. $%Invalid input detected at '^'
marker. If the operator has given an invalid input parameter in the command, then the message
conveys to the operator an invalid input was detected. The layout of the output is depicted below:
(exec) #show arpp brief
^
%Invalid input detected at ‘^’ marker.
FIGURE 2. Syntax Error Message
After all the mandatory parameters are entered, any additional parameters entered are treated as
optional parameters. If any of the parameters are not recognized a syntax error message will be
displayed.
2. After the command is successfully parsed and validated, the control of execution goes to the
corresponding CLI callback function.
3. For mandatory parameters, the command tree extends till the mandatory parameters make the
leaf of the branch. The callback function is only invoked when all the mandatory parameters
are provided. For optional parameters, the command tree extends till the mandatory
parameters and the optional parameters make the leaf of the branch. However, the call back
function is associated with the node where the mandatory parameters are fetched. The call
back function then takes care of the optional parameters.
4. Once the control has reached the callback function, the callback function has complete
information about the parameters entered by the operator.

“No” Form of a Command
"No" is a specific form of an existing command and does not represent a new or distinct command.
Only the configuration commands are available in the "no"form. The behavior and the support
details of the “no” form is captured as part of the mapping sheets. The mapping sheets are
Support for “No” Form
Almost every configuration command has a “no” form. In general, use the no form to reverse the
action of a command or reset a value back to the default. For example, the “no shutdown interface’
configuration command reverses the shutdown of an interface. Use the command without the
keyword no to re-enable a disabled feature or to enable a feature that is disabled by default.
Behavior of Command Help ("?")
The "no"form is treated as a specific form of an existing command and does not represent a new or
distinct command. This implies that the behavior of the "?" and help text is the same for the “no”
form:
•
The help message is the same for all forms of the command. The help string may be
augmented with details about the "no" form behavior.
•
For the (no config interface?) and (no config inte?) cases of the "?", the options displayed are
identical to the case when the "no" token is not specified.

Locally Administered MAC Address If desired, a locally administered MAC address
can be configured for in-band connectivity. To take effect, 'MAC
Address Type' must be set to 'Locally Administered'. Enter the
address as twelve hexadecimal digits (6 bytes) with a colon
between each byte. Bit 1 of byte 0 must be set to a 1 and bit 0 to a
0, i.e. byte 0 should have the following mask 'xxxx xx10'. The
MAC address used by this bridge when it must be referred to in a
unique fashion. It is recommended that this be the numerically
smallest MAC address of all ports that belong to this bridge.
However it is only required to be unique. When concatenated
with dot1dStpPriority a unique BridgeIdentifier is formed which
is used in the Spanning Tree Protocol.
MAC Address Type
Specifies which MAC address should be used for in-band con-
nectivity. The choices are the burned in or the Locally Adminis-
tered address. The factory default is to use the burned in MAC
address.
Network Configuration Protocol Current Indicates which network protocol is being
used. The options are bootp | dhcp | none.

SNMP Community Commands
show snmpcommunity
This command displays SNMP community information. Six communities are supported. You can
add, change, or delete communities. The switch does not have to be reset for changes to take
effect.
The SNMP agent of the switch complies with SNMP Version 1 (for more about the SNMP
specification, see the SNMP RFCs). The SNMP agent sends traps through TCP/IP to an external
SNMP manager based on the SNMP configuration (the trap receiver and other SNMP community
parameters).
Format
Mode
show snmpcommunity
Privileged EXEC
SNMP Community Name The community string to which this entry grants access. A valid
entry is a case-sensitive alphanumeric string of up to 16 charac-
ters. Each row of this table must contain a unique community
name.
Client IP Address -
An IP address (or portion thereof) from which this device will
accept SNMP packets with the associated community. The
requesting entity's IP address is ANDed with the Subnet Mask
before being compared to the IP Address. Note: that if the Subnet
Mask is set to 0.0.0.0, an IP Address of 0.0.0.0 matches all IP
addresses. The default value is 0.0.0.0
Client IP Mask -
A mask to be ANDed with the requesting entity's IP address
before comparison with IP Address. If the result matches with IP
Address then the address is an authenticated IP address. For
example, if the IP Address = 9.47.128.0 and the corresponding
Subnet Mask = 255.255.255.0 a range of incoming IP addresses
would match, i.e. the incoming IP Address could equal
9.47.128.0 - 9.47.128.255. The default value is 0.0.0.0

storm-control broadcast
This command enables broadcast storm recovery mode. If the mode is enabled, broadcast storm
recovery with high and low thresholds is implemented.
The threshold implementation follows a percentage pattern. If the broadcast traffic on any Ethernet
port exceeds the high threshold percentage (as represented in Table 1) of the link speed, the switch
discards the broadcasts traffic until the broadcast traffic returns to the low threshold percentage or

DHCP Server Commands
These commands configure the DHCP Server parameters and address pools. The commands are
divided by functionality into these different groups:
•
Configuration Commands are used to configure features and options of the switch. For every
configuration command there is a show command that will display the configuration setting.
•
•
Show commands are used to display switch settings, statistics and other information.
Clear commands clear some or all of the settings to factory defaults.

client-identifier
This command specifies the unique identifier for a DHCP client. Unique-identifier is a valid
notation in hexadecimal format. In some systems, such as Microsoft DHCP clients, the client
identifier is required instead of hardware addresses. The unique-identifier is a concatenation of the
media type and the MAC address. For example, the Microsoft client identifier for Ethernet address
c819.2488.f177 is 01c8.1924.88f1.77 where 01 represents the Ethernet media type. Refer to the
"Address Resolution Protocol Parameters" section of RFC 1700, Assigned Numbers for a list of
media type codes.

configuration command, there is a show command that displays the configuration setting.
Note: The software platform STP default mode is IEEE 802.1s, but the legacy IEEE 802.1D mode
is available. To change to the legacy IEEE 802.1D mode, set the STP operational mode to
disabled, then enable the IEEE 802.1D mode from the source code. Recompile the software to
operationally enable the IEEE 802.1D mode. With the IEEE 802.1D mode operationally enabled,
the rapid configuration and multiple instances features are not available. If the rapid configuration
and multiple instances capabilities are required, use the IEEE 802.1s mode which is compatible
with the legacy IEEE 802.1D standard.

authentication login
This command creates an authentication login list. The <listname> is any character string and is
not case sensitive. Up to 10 authentication login lists can be configured on the switch. When a list
is created, the authentication method “local” is set as the first method.
When the optional parameters “Option1”, “Option2” and/or “Option3” are used, an ordered list of
methods are set in the authentication login list. If the authentication login list does not exist, a new
authentication login list is first created and then the authentication methods are set in the
authentication login list. The maximum number of authentication login methods is three. The
possible method values are local, radius and reject.
The value of localindicates that the user’s locally stored ID and password are used for
authentication. The value of radiusindicates that the user’s ID and password will be authenticated
using the RADIUS server. The value of reject indicates the user is never authenticated.
To authenticate a user, the authentication methods in the user’s login will be attempted in order
until an authentication attempt succeeds or fails.
Note: The default login list included with the default configuration can not be changed.

If the 'auth' token is used, the command configures the IP address to use to connect to a RADIUS
authentication server. Up to 3 servers can be configured per RADIUS client. If the maximum
number of configured servers is reached, the command will fail until one of the servers is removed
by executing the no form of the command. If the optional <port> parameter is used, the command
will configure the UDP port number to use to connect to the configured RADIUS server. In order
to configure the UDP port number, the IP address must match that of a previously configured
RADIUS authentication server. The port number must lie between 1 - 65535, with 1812 being the
default value.
If the 'acct' token is used, the command configures the IP address to use for the RADIUS
accounting server. Only a single accounting server can be configured. If an accounting server is
currently configured, it must be removed from the configuration using the no form of the
command before this command succeeds. If the optional <port> parameter is used, the command
will configure the UDP port to use to connect to the RADIUS accounting server. The IP address
specified must match that of a previously configured accounting server. If a port is already
configured for the accounting server then the new port will replace the previously configured
value. The port must be a value in the range 1 - 65535, with 1813 being the default value.

Quality of Service (QoS) Commands
This chapter provides a detailed explanation of the Quality of Service (QOS) commands. The
following QOS commands are available in the software QOS module.
The commands are divided into these different groups:
•
•
Show commands are used to display device settings, statistics and other information.
Configuration Commands are used to configure features and options of the switch. For every
configuration command there is a show command that will display the configuration setting.
Access Control List (ACL) Commands
Access Control Lists (ACLs) ensure that only authorized users have access to specific resources
while blocking off any unwarranted attempts to reach network resources.
Note:
ACL configuration for IP packet fragments is not supported.
The maximum number of rules per ACL translates into the number of hardware
classifier entries used when an ACL is attached to an interface. Increasing these
values in the software increases the RAM and NVSTORE usage.
ACLs are configured separately for Layer 2 and Layer 3/Layer 4. Some types of
hardware do not allow both types of ACLs to be applied to the same interface.
mac access-list extended <name>
This command creates a MAC Access Control List (ACL) identified by <name>, consisting of
classification fields defined for the Layer 2 header of an Ethernet frame. The <name> parameter is
a case-sensitive alphanumeric string from 1 to 31 characters uniquely identifying the MAC access
list.
If a MAC ACL by this name already exists, this command enters Mac-Access-List config mode to
allow updating the existing ACL.

mac access-list extended rename <name> <newname>
This command changes the name of a MAC Access Control List (ACL). The <name> parameter
is the name of an existing MAC ACL. The <newname> parameter is a case-sensitive
alphanumeric string from 1 to 31 characters uniquely identifying the MAC access list.
This command fails if a MAC ACL by the name <newname> already exists.
Format
Mode
mac access-list extended rename <name> <newname>
Global Config
{deny|permit} <srcmac> <srcmacmask> <dstmac>
<dstmacmask>
This command creates a new rule for the current MAC access list. Each rule is appended to the list
of configured rules for the list. Note that an implicit 'deny all' MAC rule always terminates the
access list.
Note: The 'no' form of this command is not supported, as the rules within an ACL cannot be
deleted individually. Rather, the entire ACL must be deleted and re-specified.
A rule may either deny or permit traffic according to the specified classification fields. At a
minimum, the source and destination MAC value and mask pairs must be specified, each of which
may be substituted using the keyword any to indicate a match on any value in that field. The bpdu
keyword may be specified for the destination MAC value/mask pair indicating a well-known
BPDU MAC value of 01-80-c2-xx-xx-xx (hex), where 'xx' indicates a don't care. The remaining
command parameters are all optional.

The Ethertype may be specified as either a keyword or a four-digit hexadecimal value from
0x0600-0xFFFF. The currently supported <ethertypekey> values are: appletalk, arp, ibmsna,
ipv4, ipv6, ipx, mplsmcast, mplsucast, netbios, novell, pppoe, rarp. Each of these translates into
its equivalent Ethertype value(s).
The assign-queue parameter allows specification of a particular hardware queue for handling
traffic that matches this rule. The allowed <queue-id> value is 0-(n-1), where n is the number of
user configurable queues available for the hardware platform. The redirect parameter allows the
traffic matching this rule to be forwarded to the specified <slot/port>. The assign-queue and
redirect parameters are only valid for a 'permit' rule.
Format
{deny|permit} {{<srcmac> <srcmacmask} | any} {{<dst-
mac> <dstmacmask>} | any | bpdu} [<ethertypekey> |
<0x0600-0xFFFF>] [vlan {{eq <0-4095>} | {range <0-

4095>} | {range <0-4095> <0-4095>}}] [secondary-cos
<0-7>] [assign-queue <queue-id>] [redirect <slot/

Note that the special command form {deny|permit} any any is used to match all Ethernet layer 2
packets, and is the equivalent of the IP access list "match every" rule.
Mode
Mac-Access-List Config
mac access-group <name> {in|out} [sequence <1-4294967295>]
This command attaches a specific MAC Access Control List (ACL) identified by <name> to an
interface in a given direction. The <name> parameter must be the name of an exsiting MAC ACL.
An optional sequence number may be specified to indicate the order of this access list relative to
other access lists already assigned to this interface and direction. A lower number indicates higher
precedence order. If a sequence number is already in use for this interface and direction, the
specified access list replaces the currently attached access list using that sequence number. If the
sequence number is not specified for this command, a sequence number that is one greater than the
highest sequence number currently in use for this interface and direction will be used.
This command specified in 'Interface Config' mode only affects a single interface, whereas the
'Global Config' mode setting is applied to all interfaces. The 'Interface Config' mode command is
only available on platforms that support independent per-port class of service queue configuration.

access-list
This command creates an Access Control List (ACL) that is identified by the parameter
<accesslistnumber>. The ACL number is an integer from 1 to 199. The range 1 to 99 is for
normal ACL List and 100 to 199 is extended ACL List. The ACL rule is created with the option of
permit or deny . The protocol to filter for an ACL rule is specified by giving the protocol to be
used like cmp,igmp,ip,tcp,udp. The command specifies a source ipaddress and source mask for
match condition of the ACL rule specified by the srcip and srcmask parameters.The source layer 4
port match condition for the ACL rule are specified by the port value parameter.The <startport>
and <endport> parameters identify the first and last ports that are part of the port range. They
have values from 0 to 65535. The ending port must have a value equal or greater than the starting
port. The starting port, ending port, and all ports in between will be part of the destination port
range.The <portvalue> parameter uses a single keyword notation and currently has the values of
domain, echo, ftp, ftpdata, http, smtp, snmp, telnet, tftp, and www. Each of these
values translates into its equivalent port number, which is used as both the start and end of a port
range. The command specifies a destination ipaddress and destination mask for match condition of
the ACL rule specified by the dstip and dstmask parameters.The command specifies the TOS for
an ACL rule depending on a match of precedence or DSCP values using the parameters tos,
tosmask ,dscp.

Differentiated Services (DiffServ) Commands
This chapter contains the CLI commands used for the QOS Differentiated Services (DiffServ)
package.
The user configures DiffServ in several stages by specifying:
1. Class
creating and deleting classes
defining match criteria for a class. Note: The only way to remove an individual
match criterion from an existing class definition is to delete the class and re-cre-
ate it.
2. Policy
creating and deleting policies
associating classes with a policy
defining policy statements for a policy/class combination
3. Service
adding and removing a policy to/from a directional (i.e., inbound, outbound)
interface
Packets are filtered and processed based on defined criteria. The filtering criteria is defined by a
class. The processing is defined by a policy's attributes. Policy attributes may be defined on a per-
class instance basis, and it is these attributes that are applied when a match occurs.
Packet processing begins by testing the match criteria for a packet. A policy is applied to a packet
when a class match within that policy is found.

User Manual for the NETGEAR 7300S Series Layer 3 Managed Switch Software
Note that the type of class - all, any, or acl - has a bearing on the validity of match criteria specified
when defining the class. A class type of 'any' processes its match rules in an ordered sequence;
additional rules specified for such a class simply extend this list. A class type of ‘acl’ obtains its
rule list by interpreting each ACL rule definition at the time the Diffserv class is created.
Differences arise when specifying match criteria for a class type 'all', since only one value for each
non-excluded match field is allowed within a class definition. If a field is already specified for a
class, all subsequent attempts to specify the same field fail, including the cases where a field can
be specified multiple ways through alternative formats. The exception to this is when the 'exclude'
option is specified, in which case this restriction does not apply to the excluded fields.
The following class restrictions are imposed by the DiffServ design:
•
nested class support limited to:
'any' within 'any'
'all' within 'all'
no nested 'not' conditions
no nested 'acl' class types
each class contains at most one referenced class
•
•
hierarchical service policies not supported in a class definition
access list matched by reference only, and must be sole criterion in a class
i.e., ACL rules copied as class match criteria at time of class creation, with class
type 'any'
implicit ACL 'deny all' rule also copied
no nesting of class type 'acl'
Regarding nested classes, referred to here as class references, a given class definition can contain
at most one reference to another class, which can be combined with other match criteria. The
referenced class is truly a reference and not a copy, since additions to a referenced class affect all
classes that reference it. Changes to any class definition currently referenced by any other class
must result in valid class definitions for all derived classes otherwise the change is rejected. A
class reference may be removed from a class definition.
The user can display summary and detailed information for classes, policies and services. All
configuration information is accessible via the CLI, Web, and SNMP user interfaces.

Class Commands
The 'class' command set is used in DiffServ to define:
Traffic Classification
Specify Behavior Aggregate (BA), based on DSCP, and Multi-
Field (MF) classes of traffic (name, match criteria)
Service Levels
Specify the BA forwarding classes / service levels. Conceptually,
DiffServ is a two-level hierarchy of classes: 1. Service/PHB, 2.
Traffic Class
This set of commands consists of class creation/deletion and matching, with the class match
commands specifying layer 3, layer 2, and general match criteria. The class match criteria are also
known as class rules, with a class definition consisting of one or more rules to identify the traffic
belonging to the class. Note that once a class match criterion is created for a class, it cannot be
changed or deleted - the entire class must be deleted and re-created.
The CLI command root is class-map.
class-map
This command defines a new DiffServ class of type match-all, match-any or match-access-group.
The <classname> parameter is a case sensitive alphanumeric string from 1 to 31 characters
uniquely identifying the class (Note: the class name 'default' is reserved and must not be used
here).
When used without any match condition, this command enters the class-map mode. The
<classname> is the name of an existing DiffServ class (note: the class name 'default' is reserved
and is not allowed here)

The class type of match-all indicates all of the individual match conditions must be true for a
packet to be considered a member of the class.
The class type of match-any indicates only one of the match criteria must be true for a packet to
belong to the class; multiple matching criteria are evaluated in a sequential order, with the highest
precedence awarded to the first criterion defined for the class.
The class type of match-access-group indicates the individual class match criteria are evaluated
based on an access list (ACL). The <aclid> parameter is an integer specifying an existing ACL
number (refer to the appropriate ACL documentation for the valid ACL number range). A match-
access-group class type copies its set of match criteria from the current rule definition of the
specified ACL number. All elements of a single ACL Rule are treated by DiffServ as a grouped
set, similar to class type all. For any class, at least one class match condition must be specified for
the class to be considered valid.
Note: The class match conditions are obtained from the referenced access list at the time of class
creation. Thus, any subsequent changes to the referenced ACL definition do not affect the
DiffServ class. To pick up the latest ACL definition, the DiffServ class must be deleted and re-
created.
This command may be used without specifying a class type to enter the Class-Map Config mode
for an existing DiffServ class.
Note: The CLI mode is changed to Class-Map Config when this command is successfully
executed.

This command adds to the specified class definition a match condition based on the destination
layer 4 port of a packet using a single keyword or numeric notation or a numeric range notation.
To specify the match condition as a single keyword, the value for <portkey> is one of the supported
port name keywords. The currently supported <portkey> values are: domain, echo, ftp, ftpdata, http,
smtp, snmp, telnet, tftp, www. Each of these translates into its equivalent port number, which is used as
both the start and end of a port range.
To specify the match condition using a numeric notation, one layer 4 port number is required. The
port number is an integer from 0 to 65535.
To specify the match condition using a numeric range notation, two layer 4 port numbers are
required and together they specify a contiguous port range. Each port number is an integer from 0
to 65535, but with the added requirement that the second number be equal to or greater than the
first.
The optional [not] parameter has the effect of negating this match condition for the class (i.e.,
match all destination layer 4 port numbers except for the one specified here).

match ip dscp
This command adds to the specified class definition a match condition based on the value of the IP
DiffServ Code Point (DSCP) field in a packet, which is defined as the high-order six bits of the
Service Type octet in the IP header (the low-order two bits are not checked). The optional [not]
parameter has the effect of negating this match condition for the class (i.e., match all IP DSCP
values except for what is specified here). The <dscpval> value is specified as either an integer from
0 to 63, or symbolically through one of the following keywords: af11, af12, af13, af21, af22, af23, af31,
af32, af33, af41, af42, af43, be, cs0, cs1, cs2, cs3, cs4, cs5, cs6, cs7, ef.
Note: The ip dscp, ip precedence, and ip tos match conditions are alternative ways to specify a
match criterion for the same Service Type field in the IP header, but with a slightly different user
notation.
Note: To specify a match on all DSCP values, use the match [not] ip tos <tosbits> <tosmask>
command with <tosbits> set to 0 and <tosmask> set to 03 (hex).

This command adds to the specified class definition a match condition based on the value of the IP
Precedence field in a packet, which is defined as the high-order three bits of the Service Type octet

0 to 7. The optional [not] parameter has the effect of negating this match condition for the class
(i.e., match all IP Precedence values except for what is specified here).
Note: The ip dscp, ip precedence, and ip tos match conditions are alternative ways to specify a
match criterion for the same Service Type field in the IP header, but with a slightly different user
notation.
Note: To specify a match on all Precedence values, use the match [not] ip tos <tosbits> <tosmask>

match ip tos
This command adds to the specified class definition a match condition based on the value of the IP
TOS field in a packet, which is defined as all eight bits of the Service Type octet in the IP header.
The value of <tosbits> is a two-digit hexadecimal number from 00 to ff. The value of <tosmask> is a
two-digit hexadecimal number from 00 to ff. The optional [not] parameter has the effect of
negating this match condition for the class (i.e., match all IP Precedence values except for what is
specified here). The <tosmask> denotes the bit positions in <tosbits> that are used for comparison
against the IP TOS field in a packet. For example, to check for an IP TOS value having bits 7 and
5 set and bit 1 clear, where bit 7 is most significant, use a <tosbits> value of a0 (hex) and a
<tosmask> of a2 (hex).
Note: The ip dscp, ip precedence, and ip tos match conditions are alternative ways to specify a
match criterion for the same Service Type field in the IP header, but with a slightly different user
notation.
Note: In essence, this the “free form” version of the IP DSCP/Precedence/TOS match specification
in that the user has complete control of specifying which bits of the IP Service Type field are
checked.

match protocol
This command adds to the specified class definition a match condition based on the value of the IP
Protocol field in a packet using a single keyword notation or a numeric value notation.
To specify the match condition using a single keyword notation, the value for <protocol-name> is
one of the supported protocol name keywords. The currently supported values are: icmp, igmp, ip,
tcp, udp. Note that a value of ip is interpreted to match all protocol number values.
To specify the match condition using a numeric value notation, the protocol number is a standard
value assigned by IANA and is interpreted as an integer from 0 to 255. Note: This command does
not validate the protocol number value against the current list defined by IANA.
The optional [not] parameter has the effect of negating this match condition for the class (i.e.,
match all IP Protocol numbers except for the one specified here).

Policy Commands
The 'policy' command set is used in DiffServ to define:
Traffic Conditioning
Specify traffic conditioning actions (policing, marking, shaping)
to apply to traffic classes
Service Provisioning
Specify bandwidth and queue depth management requirements of
service levels (EF, AF, etc.)
The policy commands are used to associate a traffic class, which was defined by the class
command set, with one or more QoS policy attributes. This association is then assigned to an
interface to form a service. The user specifies the policy name when the policy is created.

User Manual for the NETGEAR 7300S Series Layer 3 Managed Switch Software
The DiffServ CLI does not necessarily require that users associate only one traffic class to one
policy. In fact, multiple traffic classes can be associated with a single policy, each defining a
particular treatment for packets that match the class definition. When a packet satisfies the
conditions of more than one class, preference is based on the order in which the classes were added
to the policy, with the foremost class taking highest precedence.
This set of commands consists of policy creation/deletion, class addition/removal, and individual
policy attributes. Note that the only way to remove an individual policy attribute from a class
instance within a policy is to remove the class instance and re-add it to the policy. The values
associated with an existing policy attribute can be changed without removing the class instance.
The CLI command root is policy-map.

no policy-map
This command eliminates an existing DiffServ policy. The <policyname>parameter is the name
of an existing DiffServ policy. This command may be issued at any time; if the policy is currently
referenced by one or more interface service attachments, this deletion attempt shall fail.
Format
Mode

randomdrop
This command changes the active queue depth management scheme from the default tail drop to
RED. The first two data parameters are the average queue depth minimum and maximum
threshold values specified in bytes. The minimum threshold is an integer from 1 to 250000. The
maximum threshold is an integer from 1 to 500000, but it must be equal to or greater than the
minimum threshold. The third data parameter is the maximum drop probability and is an integer
from 0 to 100. It indicates the percentage likelihood that a packet will be dropped when the
average queue depth reaches the maximum threshold value.

The remaining parameters are all optional. The fourth data parameter is the sampling rate,
indicating the period at which the queue is sampled for computing the average depth. Expressed in
microseconds, the sampling rate is an integer from 0 to 1000000, with a default of 0 (meaning per-
packet sampling). The last parameter is the decay exponent, which determines how quickly the
average queue length calculation decays over time, with a higher number producing a faster rate of
decay. This value is an integer from 0 to 16, with a default of 9.
Note: The last two parameters, namely sampling rate and decay exponent, are hierarchically
specified in this command. That is, in order to provide a value for the decay exponent <0-16>, the
user is required to also specify a sampling rate <0-1000000>for proper command interpretation.

shape average
This command is used to establish average rate traffic shaping for the specified class, which limits
transmissions for the class to the committed information rate, with excess traffic delayed via
queueing. The committed information rate is specified in kilobits-per-second (Kbps) and is an
integer from 1 to 4294967295.
Note: Queue depth management defaults to tail drop, but the randomdrop command can be used
to change to a RED scheme.

Restrictions
This shaping rate must not exceed the maximum link data rate of
the interface to which the policy is applied.

Out
shape peak
This command is used to establish peak rate traffic shaping for the specified class, which allows
transmissions for the class to exceed the committed information rate by sending excess traffic with
the understanding that it could be dropped by a downstream network element. Two rate parameters
are used, a committed information rate and a peak information rate. Each of these rates is specified
in kilobits-per-second (Kbps) and is an integer from 1 to 4294967295. The peak rate must be
specified as equal to or greater than the committed rate.

Service Commands
The 'service' command set is used in DiffServ to define:
Traffic Conditioning
Assign a DiffServ traffic conditioning policy (as specified by the
policy commands) to an interface in the incoming direction
Service Provisioning
Assign a DiffServ service provisioning policy (as specified by the
policy commands) to an interface in the outgoing direction
The service commands attach a defined policy to a directional interface. Only one policy may be
assigned at any one time to an interface in a particular direction. The policy type (in, out) must
match the interface direction to which it is attached.
This set of commands consists of service addition/removal.
The CLI command root is service-policy
service-policy
This command attaches a policy to an interface in a particular direction. The command can be used
in the Interface Config mode to attach a policy to a specific interface. Alternatively, the command
can be used in the Global Config mode to attach this policy to all system interfaces. The direction
value is either in or out. The <policyname>parameter is the name of an existing DiffServ policy,
whose type must match the interface direction. Note that this command causes a service to create a
reference to the policy.
Note: This command effectively enables DiffServ on an interface (in a particular direction). There
is no separate interface administrative 'mode' command for DiffServ.

This chapter provides a detailed explanation of the software QoS CoS commands. The following
commands are available in the software QOS module.
The commands are divided into these different groups:
•
Configuration Commands are used to configure features and options of the switch. For every
configuration command there is a show command that will display the configuration setting.
•
Show commands are used to display device settings, statistics and other information.
Note: The 'Interface Config' mode only affects a single interface, whereas the 'Global Config'
mode is applied to all interfaces.
classofservice dot1p-mapping
This command maps an 802.1p priority to an internal traffic class. The userpriority and
trafficclass can both range from 0-7, although the actual number of available traffic classes

Understanding Switch Stacks
A switch stack is a set of up to eight Ethernet switches connected through their stacking ports. One
of the switches controls the operation of the stack and is called the stack master. The stack master
and the other switches in the stack are stack members. The stack members use stacking technology
to behave and work together as a unified system. Layer 2 and Layer 3 protocols present the entire
switch stack as a single entity to the network.
The stack master is the single point of stack-wide management. From the stack master, you
configure:
•
•
System-level (global) features that apply to all stack members
Interface-level features for all interfaces on any stack member

User Manual for the NETGEAR 7300S Series Layer 3 Managed Switch Software
A switch stack is identified in the network by its network IP address. The network IP address is
assigned according to the MAC address of the stack master. Every stack member is uniquely
identified by its own stack member number.
All stack members are eligible stack masters. If the stack master becomes unavailable, the
remaining stack members participate in electing a new stack master from among themselves. A set
of factors determine which switch is elected the stack master. These factors are:
1. The switch who is master always has priority to retain the role of master
2. Assigned priority
3. MAC address
If the master cannot be selected by (1), then (2) is used. If (2) does not resolve which stack member
becomes stack master, then (3) is used.
The stack master contains the saved and running configuration files for the switch stack. The
configuration files include the system-level settings for the switch stack and the interface-level
settings for all stack members. Each stack member retains a copy of the saved file for backup
purposes.
If the master is removed from the stack, another member will be elected master, and will then run
from that saved configuration.
You can use these methods to manage switch stacks:
•
•
•
Stack web interface
Command line interface (CLI) over a serial connection to the console port of the master
A network management application through the Simple Network Management Protocol
(SNMP)
Switch Stack Membership
A switch stack has up to eight stack members connected through their stacking ports. A switch
stack always has one stack master.
A standalone switch is a switch stack with one stack member that also operates as the stack master.
You can connect one standalone switch to another to create a switch stack containing two stack
members, with one of them being the stack master. You can connect standalone switches to an
existing switch stack to increase the stack membership.

User Manual for the NETGEAR 7300S Series Layer 3 Managed Switch Software
If you replace a stack member with an identical model, the new switch functions with exactly the
same configuration as the replaced switch, assuming that the new switch is using the same member
number as the replaced switch. For information about the benefits of preconfiguring a switch
The operation of the switch stack continues uninterrupted during membership changes unless you
remove the stack master or you add powered-on standalone switches or switch stacks.
•
Adding powered-on switches (merging) causes the stack masters of the merging switch stacks
to elect a stack master from among themselves. The re-elected stack master retains its role and
configuration and so do its stack members. All remaining switches, including the former stack
masters, reload and join the switch stack as stack members. They change their stack member
numbers to the lowest available numbers and use the stack configuration of the re-elected
stack master. Therefore, when you merge two powered stacks, you cannot control which unit
becomes stack master and which configuration is used. For these reasons, it is recommended
that powered switches be powered down before adding to an existing operating stack.
•
Removing powered-on stack members can cause the switch stack to divide (partition) into two
or more switch stacks, each with the same configuration. However, if cabled properly, the
switch stack should not divide.
–
If the switch stack divides, and you want the switch stacks to remain separate, change the
IP address or addresses of the newly created switch stacks.
–
If you did not intend to partition the switch stack:
•
•
•
Power off the newly created switch stacks
Reconnect them to the original switch stack through their stacking ports
Power on the switches

Stack Master Election and Re-Election
The stack master is elected or re-elected based on one of these factors and in the order listed:
1. The switch that is currently the stack master
2. The switch with the highest stack member priority value
Note: Netgear recommends assigning the highest priority value to the switch that you prefer to
be the stack master. This ensures that the switch is re-electedas stack master if a re-election
occurs.
3. The switch with the higher MAC address
A stack master retains its role unless one of these events occurs:
•
•
•
•
The stack master is removed from the switch stack
The stack master is reset or powered off
The stack master has failed
The switch stack membership is increased by adding powered-on standalone switches or
switch stacks
In the case of a master re-election, the new stack master becomes available after a few seconds. In
the meantime, the switch stack uses the forwarding tables in memory to minimize network
disruption. The physical interfaces on the other available stack members are not affected while a
new stack master is elected.
If a new stack master is elected and the previous stack master becomes available, the previous
stack master does not resume its role as stack master.
Stack Member Numbers
A stack member number (1 to 8) identifies each member in the switch stack. The member number
also determines the interface-level configuration that a stack member uses. You can display the
stack member number by using the show switch user EXEC command.
A new, out-of-the-box switch (one that has not joined a switch stack or has not been manually
assigned a stack member number) ships with a default stack member number of 1. When it joins a
switch stack, its default stack member number changes to the lowest available member number in
the stack.

Stack members in the same switch stack cannot have the same stack member number. Every stack
member, including a standalone switch, retains its member number until you manually change the
number or unless the number is already being used by another member in the stack.
Stack Member Priority Values
A stack member priority can be changed if the user would like change who is the master of the
stack. Use the following command to change stack member's priority (this command is in the
global config mode):
switch unit priority value
Switch Stack Offline Configuration
You can use the offline configuration feature to preconfigure (supply a configuration to) a new
switch before it joins the switch stack. You can configure in advance the stack member number,
the switch type, and the interfaces associated with a switch that is not currently part of the stack.
Effects of Adding a Preconfigured Switch to a Switched Stack
When you add a preconfigured switch to the switch stack, the stack applies either the
preconfigured configuration or the default configuration. Table 12-1 lists the events that occur
when the switch stack compares the preconfigured configuration with the new switch:

Scenario
Results of comparing the preconfiguration with the new switch
Result
The stack member numbers and the switch types
match.
The switch stack applies the configuration to the
preconfigured new switch and adds it to the stack.
• If the stack member number of the preconfigured
switch matches the stack member number in the
configuration on the stack, and
• If the switch type of the preconfigured switch
matches the switch type in the configuration on
the stack.
The stack member numbers match but the switch
types do not match.
• If the stack member number of the preconfigured
switch matches the stack member number in the
configuration on the stack, but
• The switch stack applies the default configuration
to the preconfigured switch and adds it to the
stack.
• The configuration in the preconfigured switch is
changed to reflect the new information.
• The switch type of the preconfigured switch does
not match the switch type in the configuration on
the stack.
The stack member number is not found in the
configuration.
• The switch stack applies the default configuration
to the new switch and adds it to the stack.
• The preconfigured information is changed to
reflect the new information.
The stack member number of the preconfigured
switch is not found in the configuration.
The switch stack applies the default configuration to
the preconfigured switch and adds it to the stack.
Effects of Replacing a Preconfigured Switch in a Switch Stack
When a preconfigured switch in a switch stack fails, is removed from the stack, and is replaced
with another switch, the stack applies either the preconfiguration or the default configuration to it.
The events that occur when the switch stack compares the configuration with the preconfigured
switch are the same as those described in “Effects of Adding a Preconfigured Switch to a Switched
Effects of Removing a Preconfigured Switch from a Switch Stack
If you remove a preconfigured switch from the switch stack, the configuration associated with the
removed stack member remains in the running configuration as configured information. To
completely remove the configuration, use the no member unit_number (this is in the stacking
configuration mode).

Switch Stack Software Compatibility Recommendations
All stack members must run the same software version to ensure compatibility between stack
members. The software versions on all stack members, including the stack master, must be the
same. This helps ensure full compatibility in the stack protocol version among the stack members.
If a stack member is running a software version that is not the same as the stack master, then the
stack member is not allowed to join the stack. Use the show switch command to list the stack
Incompatible Software and Stack Member Image Upgrades
You can upgrade a switch that has an incompatible software image by using the archive
download-sw xmodem | ymodem | zmodem | tftp://ip/filepath/filename command (this is in the
stacking configuration mode). It copies the software image from an existing stack member to the
one with incompatible software. That switch automatically reloads and joins the stack as a fully
functioning member.
Switch Stack Configuration Files
The configuration files record settings for all global and interface specific settings that define the
operation of the stack and individual members. Once a save config command is issued, all stack
members store a copy of the configuration settings. If a stack master becomes unavailable, any
stack member assuming the role of stack master will operate from the saved configuration files.
When a new, out-of-box switch joins a switch stack, it uses the system-level settings of that switch
stack. However, if you want it to store this system level configuration, you must issue a save
config command.
You back up and restore the stack configuration in the same way as you would for standalone
switch configuration by using the copy command.

Switch Stack Management Connectivity
You manage the switch stack and the stack member interfaces through the stack master. You can
use the web interface, the CLI, and SNMP. You cannot manage stack members on an individual
switch basis.
Connectivity to the Switch Stack Through Console Ports
You can connect to the stack master through the console port of the stack master only.
Connectivity to the Switch Stack Through Telnet
You can connect to the stack master using telnet by telnetting to the ip address of the stack.

existing stack masters
Note: This is not recommended.
• Connect two powered-on switch stacks through
the stacking ports.
Only one of the two stack masters becomes the
new stack master. None of the other stack
members become the stack master.
Stack master election specifically determined by
the stack member priority value
The stack member with the higher priority value is
elected stack master.
• Connect two switches through their stacking
ports.
• Use the switch stack-member-number priority
new-priority-number global configuration
command to set one stack member to a higher
member priority value.
• Restart both stack members at the same time.

the command has fully completed before issuing the next command. For example, if a reset is
issued to a stack member, use the “show port” command to verify that the unit has remerged
with the stack, and all ports are joined before issuing the next command.
•
•
When physically removing or relocating a unit, always power down the unit before
disconnecting stack cables.
When reconnecting stack cables, connect them before powering up the unit, if possible, and
insure a good connection by tightening all connector screws (where applicable).
Initial installation and Power-up of a Stack
1. Install units in rack.
2. Install all stacking cables. Fully connect, including the redundant stack link. It is highly
recommended that a redundant link be installed.
3. Identify the unit to be the master. Power this unit up first.
4. Monitor the console port. Allow this unit to come up to the login prompt. If unit has the default
configuration, it should come up as unit #1, and will automatically become a master unit. If
not, renumber as desired.
5. If desired, preconfigure other units to be added to the stack. Preconfiguration is described in
6. Power on a second unit, making sure it is adjacent (next physical unit in the stack) to the unit
already powered up. This will insure the second unit comes up as a member of the stack, and
not a “Master” of a separate stack.
7. Monitor the master unit to see that the second unit joins the stack. Use the “show switch”
command to determine when the unit joins the stack. It will be assigned a unit number (unit
#2, if it has the default configuration).
recommendations for renumbering stack members.
9. Repeat steps 6 through 8 to add additional members to the stack. Always power on a unit
adjacent to the units already in the stack.

Removing a Unit from the Stack
1. Make sure the redundant stack connection is in place and functional. All stack members
should be connected in a logical ring.
2. Power down the unit to be removed.
3. Disconnect stack cables.
4. If unit is not to be replaced, reconnect the stack cable from the stack member above to the
stack member below the unit being removed.
5. Remove unit from the rack.
6. If desired, remove the unit from the configuration by issuing the command:
no member <unit-id>
Adding a Unit to an Operating Stack
1. Make sure the redundant stack connection is in place and functional. All stack members
should be connected in a logical ring.
2. Preconfigure the new unit, if desired.
3. Install new unit in the rack. (Assumes installation below the bottom-most unit, or above the
top-most unit).
4. Disconnect the redundant stack cable that connects the last unit in the stack back up to the first
unit in the stack at the position in the ring where the new unit is to be inserted.
5. Connect this cable to the new unit, following the established order of “stack up” to “stack
down” connections
6. Power up the new unit. Verify, by monitoring the master unit console port, that the new unit
successfully joins the stack by issuing the show switch command. The new unit should always
join as a “member” (never as master; the existing master of the stack should not change).
7. If the code version of the newly added member is not the same as the existing stack, update the
Replacing a Stack Member with a New Unit
There are two possible situations here. First, if you replace a stack member of a certain model
number with another unit of the same model, follow the process below:

Second, if you replace a stack member with another unit of a different model number, use the

Remove the now-absent stack member from the configuration by issuing the command no
member command.
Add the new stack unit to the stack using the process described in section Adding a Unit to an
Operating Stack. The unit can be inserted into the same position as the unit just removed, or
the unit can be inserted at the bottom of the stack. In either case, make sure all stack cables are
connected with the exception of the cable at the position where the new unit is to be inserted to
insure that the stack does not get divided into two separate stacks, causing the election of a
new master.
Renumbering Stack Members
1. If particular numbering is required, it is recommended that stack members be assigned specific
numbers when they are first installed and configured in the stack, if possible.
2. If the desired stack unit number for a particular unit is unused, a unit can be renumbered
simply by using the switch <oldunit-id> renumber <newunit-id> CLI command. This
command is found in global config mode.
3. If the newunit-id has been preconfigured, you may need to remove the newunit-id from the
configuration before renumbering the unit.
4. If reassignment of multiple existing stack unit numbers is necessary, there are a number of
implications in terms of mismatching of configuration. In this case, it is recommended that all
units except the master be powered down and added back one at a time using the procedure in

Moving a Master to a Different Unit in the Stack
1. Using the “movemanagement” command, move the master to the desired unit number. The
operation may take between 30 seconds and 3 minutes depending on the stack size and
configuration. The command is movemanagement <fromunit-id> <tounit-id>
2. Make sure that you can log in on the console attached to the new master. Use the show switch
command to verify that all units rejoined the stack.
3. It is recommended that the stack be reset with the reload command after moving the master.

stack.
Merging Two Operational Stacks
1. It is strongly recommended that two functioning stacks (each having an independent master)
not be merged simply by the reconnection of stack cables. That process may result in a number
of unpredictable results and should be avoided.
2. Always power off all units in one stack before connecting into another stack.
3. Add the units as a group by unplugging one stacking cable in the operational stack and
physically connecting all unpowered units at that point.
4. Completely cable the stacking connections, making sure the redundant link is also in place.

User Manual for the NETGEAR 7300S Series Layer 3 Managed Switch Software
Preconfiguration
1. General Information: All configuration on the stack except unit numbers is stored on the
management unit. This means that a stack unit may be replaced with another device of the
same type without having to reconfigure the switch. Unit numbers are stored independently on
each switch, so that after power cycling the stack the units always come back with the same
unit numbers. The unit type associated with each unit number may be learned by the
management unit automatically as the units are connected or preconfigured by the
administrator.
2. Issue the member <unit-id> <switchindex> command to preconfigure a unit. Supported unit
types are shown by the show supported switchtype command.
3. Next, configure the unit you just defined with configuration commands, just as if the unit were
physically present.
4. Ports for the preconfigured unit come up in “detached” state and can be seen with the show
port all command. The detached ports may now be configured for VLAN membership and
any other port-specific configuration.
5. After a unit type is preconfigured for a specific unit number, attaching a unit with different unit
type for this unit number causes the switch to report an error. The show switch command
indicates “config mismatch” for the new unit and the ports on that unit don’t come up. To
resolve this situation the customer may change the unit number of the mismatched unit or
delete the preconfigured unit type using the no member <unit-id> command.
Upgrading Firmware
1. New code is downloaded via TFTP or xmodem to the management unit using the copy
command. Once code is successfully loaded on the management unit, it automatically
propagates the code to the other units in the stack. If some error occurs during code
propagation to stack units then the archive command (in stack configuration mode) may be
issued to make another attempt to copy the software to the unit(s) that did not get updated.
Errors during code propagation to stack members could be caused by stack cable movement or
unit reconfiguration during the propagation phase. An error could also occur in the presence of
excessive network traffic (such as a broadcast event).

2. All units in the stack must run the same code version. Ports on stack units that don’t match the
management unit code version don’t come up and the show switch command shows a “code
mismatch” error. To resolve this situation the administrator may issue archive command. This
command copies management unit’s software to the other units with mismatched code version.
Before issuing this command, be sure the code running on the management unit is the desired
code revision for all units in the stack. Once code is loaded to all members of the stack, the
units must be reset in order for the new code to start running.
Migration of Configuration With a Firmware Upgrade
In some cases, a configuration may not be carried forward in a code update. For updates where this
issue is to be expected, the following procedure should be followed:
1. Save the current configuration by uploading it from the stack, using the copy command from
the CLI.
2. Load new code into the stack manager. Reboot the stack.
3. Upon reboot, go into the boot menu and erase the configuration (“restore to factory defaults”)
4. Continue with boot of operational code.
5. Once the stack is up, download the saved configuration back to the master. This configuration
should then be automatically propagated to all members of the stack
Code Mismatch
If a unit is added to a stack and it does not have the same version of code as that of the master, the
following should happen:
•
•
•
•
“New” unit will boot up and become a “member” of the stack
Ports on the added unit should remain in the “detached” state
A message should appear on the CLI indicating a code mismatch with the newly added unit.
To have the newly added unit to merge normally with the stack, code should be loaded to the
newly added unit from the master using the copy command. The newly added member should
then be reset, and should reboot normally and join the stack.

Appendix B
Cabling Guidelines
This appendix provides specifications for cables used with a NETGEAR NETGEAR 7300S Series
Layer 3 Managed Switch.
Fast Ethernet Cable Guidelines
Fast Ethernet uses UTP cable, as specified in the IEEE 802.3u standard for 100BASE-TX.The
specification requires Category 5 UTP cable consisting of either two-pair or four-pair twisted
insulated copper conductors bound in a single plastic sheath. Category 5 cable is certified up to
100 MHz bandwidth. 100BASE-TX operation uses one pair of wires for transmission and the
other pair for receiving and for collision detection.
When installing Category 5 UTP cabling, use the following guidelines to ensure that your cables
perform to the following specifications:
Certification
Make sure that your Category 5 UTP cable has completed the Underwriters’ Laboratories (UL) or
Electronic Testing Laboratories (ETL) certification process.
Termination method
To minimize cross-talk noise, maintain the twist ratio of the cable up to the point of termination;
untwist at any RJ-45 plug or patch panel should not exceed 0.5 inch (1.5 cm).

Category 5 Cable
Category 5 distributed cable that meets ANSI/EIA/TIA-568-A building wiring standards can be a
maximum of 328 feet (ft.) or 100 meters (m) in length, divided as follows:
20 ft. (6 m) between the hub and the patch panel (if used)
295 ft. (90 m) from the wiring closet to the wall outlet
10 ft. (3 m) from the wall outlet to the desktop device
The patch panel and other connecting hardware must meet the requirements for 100 Mbps
operation (Category 5). Only 0.5 inch (1.5 cm) of untwist in the wire pair is allowed at any
termination point.
Category 5 Cable Specifications
Ensure that the fiber cable is crossed over to guarantee link.

Twisted Pair Cables
For two devices to communicate, the transmitter of each device must be connected to the receiver
of the other device. The crossover function is usually implemented internally as part of the
circuitry in the device. Computers and workstation adapter cards are usually media-dependent
interface ports, called MDI or uplink ports. Most repeaters and switch ports are configured as
media-dependent interfaces with built-in crossover ports, called MDI-X or normal ports. Auto
Uplink technology automatically senses which connection, MDI or MDI-X, is needed and makes
the right connection.

Patch Panels and Cables
If you are using patch panels, make sure that they meet the 100BASE-TX requirements. Use
Category 5 UTP cable for all patch cables and work area cables to ensure that your UTP patch
cable rating meets or exceeds the distribution cable rating.
To wire patch panels, you need two Category 5 UTP cables with an RJ-45 plug at each end, as
shown here.

Note: Flat “silver satin” telephone cable may have the same RJ-45 plug. However, using telephone
cable results in excessive collisions, causing the attached port to be partitioned or disconnected
from the network.
Using 1000BASE-T Gigabit Ethernet over Category 5 Cable
When using the new 1000BASE-T standard, the limitations of cable installations and the steps
necessary to ensure optimum performance must be considered. The most important components in
your cabling system are patch panel connections, twists of the pairs at connector transition points,
the jacket around the twisted-pair cable, bundling of multiple pairs on horizontal runs and punch
down blocks. All of these factors affect the performance of 1000BASE-T technology if not
correctly implemented. The following sections are designed to act as a guide to correct cabling for
1000BASE-T.
Cabling
The 1000BASE-T product is designed to operate over Category 5 cabling. To further enhance the
operation, the cabling standards have been amended. The latest standard is Category 5e, which
defines a higher level of link performance than is available with Category 5 cable.
If installing new cable, we recommend using Category 5e cable, since it costs about the same as
Category 5 cable. If using the existing cable, be sure to have the cable plant tested by a
professional who can verify that it meets or exceeds either ANSI/EIA/TIA-568-A:1995 or ISO/
IEC 11801:1995 Category 5 specifications.
Length
The maximum distance limitation between two pieces of equipment is 100 m, as per the original
Ethernet specification. The end-to-end link is called the “channel.”
TSB-67 defines the “Basic Link” which is the portion of the link that is part of the building
infrastructure. This excludes patch and equipment cords. The maximum basic link length is 295
feet (90 m).
Return Loss
Return loss measures the amount of reflected signal energy resulting from impedance changes in
the cabling link. The nature of 1000BASE-T renders this measurement very important; if too much
energy is reflected back on to the receiver, the device does not perform optimally.

User Manual for the NETGEAR 7300S Series Layer 3 Managed Switch Software
Unlike 10BASE-T and 100BASE-TX, which use only two of the four pairs of wires within the
Category 5, 1000BASE-T uses all four pairs of the twisted pair. Make sure all wires are tested ⎯
this is important.
Factors that affect the return loss are:
The number of transition points, as there is a connection via an RJ-45 to another connector, a patch
panel, or device at each transition point.
Removing the jacket that surrounds the four pairs of twisted cable. It is highly recommended that,
when RJ-45 connections are made, this is minimized to 1-1/4 inch (32 mm).
Untwisting any pair of the twisted-pair cabling. It is important that any untwisting be minimized to
3/8 inch (10 mm) for RJ-45 connections.
Cabling or bundling of multiple Category 5 cables. This is regulated by ANSI/EIA/TIA-568A-3. If
not correctly implemented, this can adversely affect all cabling parameters.
Near End Cross Talk (NEXT)
This is a measure of the signal coupling from one wire to another, within a cable assembly, or
among cables within a bundle. NEXT measures the amount of cross-talk disturbance energy that is
detected at the near end of the link — the end where the transmitter is located. NEXT measures the
amount of energy that is “returned” to the sender end. The factors that affect NEXT and cross talk
are exactly the same as outlined in the Return Loss section. The cross-talk performance is directly
related to the quality of the cable installation.
Patch Cables
When installing your equipment, replace old patch panel cables that do not meet Category 5e
specifications. As pointed out in the NEXT section, this near end piece of cable is critical for
successful operation.
RJ-45 Plug and RJ-45 Connectors
In a Fast Ethernet network, it is important that all 100BASE-T certified Category 5 cabling use
RJ-45 plugs. The RJ-45 plug accepts 4-pair UTP or shielded twisted-pair (STP) 100-ohm cable
and connects into the RJ-45 connector. The RJ-45 connector is used to connect stations, hubs, and
switches through UTP cable; it supports 10 Mbps, 100 Mbps, or 1000 Mbps data transmission.

Conclusion
For optimum performance of your 1000BASE-T product, it is important to fully qualify your cable
installation and ensure it meets or exceeds ANSI/EIA/TIA-568-A:1995 or ISO/IEC 11801:1995
Category 5 specifications. Install Category 5e cable where possible, including patch panel cables.
Minimize transition points, jacket removal, and untwist lengths. Bundling of cables must be
properly installed to meet the requirements in ANSI/EIA/TIA-568A-3.

Numeric
802.1D
The IEEE designator for Spanning Tree Protocol (STP). STP, a link management protocol, is part of the
802.1D standard for media access control bridges. Using the spanning tree algorithm, STP provides path
redundancy while preventing endless loops in a network. An endless loop is created by multiple active paths
between stations where there are alternate routes between hosts. To establish path redundancy, STP creates a
logical tree that spans all of the switches in an extended network, forcing redundant paths into a standby, or
blocked, state. STP allows only one active path at a time between any two network devices (this prevents the
loops) but establishes the redundant links as a backup if the initial link should fail. If STP costs change, or if
one network segment in the STP becomes unreachable, the spanning tree algorithm reconfigures the
spanning tree topology and reestablishes the link by activating the standby path. Without spanning tree in
place, it is possible that both connections may be simultaneously live, which could result in an endless loop
of traffic on the LAN.
802.1P
The IEEE protocol designator for Local Area Network (LAN). This Layer 2 network standard improves
support of time critical traffic, and limits the extent of high bandwidth multicast traffic within a bridged
LAN. To do this, 802.1P defines a methodology for introducing traffic class priorities. The 802.1P standard
allows priority to be defined in all 802 MAC protocols (Ethernet, Token Bus, Token Ring), as well as in
FDDI. For protocols (such as Ethernet) that do not contain a priority field, 802.1P specifies a method for
indicating frame priority based on the new fields defined in the 802.1Q (VLAN) standard.
802.1Q VLAN
The IEEE protocol designator for Virtual Local Area Network (VLAN). This standard provides VLAN
identification and quality of service (QoS) levels. Four bytes are added to an Ethernet frame to allow eight
10BASE-T
The IEEE specification for 10 Mbps Ethernet over Category 3, 4, or 5 twisted-pair cable.

Access Control List
An ACL is a database that an Operating System uses to track each user’s access rights to system objects
(such as file directories and/or files).
ACL
Address Resolution Protocol
An Internet Protocol that dynamically maps Internet addresses to physical (hardware) addresses on a LAN.
Advanced Network Device Layer/Software
Term for the Device Driver level.
Aging
When an entry for a node is added to the lookup table of a switch, it is given a timestamp. Each time a packet
is received from a node, the timestamp is updated. The switch has a user-configurable timer that erases the
entry after a certain length of time with no activity from that node.
Area Border Router
A router located on the border of one or more OSPF areas that connects those areas to the backbone
network. ABRs are considered members of both the OSPF backbone and the attached areas. They therefore
maintain routing tables describing both the backbone topology and the topology of the other areas. (Cisco
Systems Inc.)

ASBR
Autonomous System Boundary Router
ABR located between an OSPF autonomous system and a non-OSPF network. ASBRs run both OSPF and
another routing protocol, such as RIP. ASBRs must reside in a non-stub OSPF area. See also ABR, non-stub
area, and OSPF. (Cisco Systems Inc.)
Auto-negotiation
A feature that allows twisted-pair ports to advertise their capabilities for speed, duplex and flow control.
When connected to a port that also supports auto-negotiation, the link can automatically configure itself to
the optimum setup.
Auto Uplink
Auto UplinkTM technology (also called MDI/MDIX) eliminates the need to worry about crossover vs.
straight-through Ethernet cables. Auto UplinkTM will accommodate either type of cable to make the right
connection.
AVL tree
Binary tree having the property that for any node in the tree, the difference in height between the left and
right subtrees of that node is no more than 1.
B
BPDU
Backbone
The part of a network used as a primary path for transporting traffic between network segments.
Bandwidth
The information capacity, measured in bits per second, that a channel could transmit. Bandwidth examples
include 10 Mbps for Ethernet, 100 Mbps for Fast Ethernet, and 1000 Mbps (I Gbps) for Gigabit Ethernet.

Bootstrap Protocol
An Internet protocol that enables a diskless workstation to discover its own IP address, the IP address of a
BootP server on the network, and a file to be loaded into memory to boot the machine. This enables the
workstation to boot without requiring a hard or floppy disk drive.
Bridge Protocol Data Unit
BPDU is the IEEE 802.1D MAC Bridge Management protocol that is the standard implementation of STP
(Spanning Tree Protocol). It uses the STP algorithm to insure that physical loops in the network topology do
not result in logical looping of network traffic. Using one bridge configured as root for reference, the BPDU
switches one of two bridges forming a network loop into standby mode, so that only one side of a potential
loop passes traffic. By examining frequent 802.1d configuration updates, a bridge in the standby mode can
switch automatically into the forward mode if the other bridge forming the loop fails.
Broadcast
A packet sent to all devices on a network.
Broadcast storm
Multiple simultaneous broadcasts that typically absorb all the available network bandwidth and can cause a
network to fail. Broadcast storms can be due to faulty network devices or network loops.
C
Cat 5
Category 5 unshielded twisted pair (UTP) cabling. An Ethernet network operating at 10 Mbits/second
(10BASE-T) will often tolerate low quality cables, but at 100 Mbits/second (10BASE-Tx) the cable must be
rated as Category 5, or Cat 5 or Cat V, by the Electronic Industry Association (EIA).
This rating will be printed on the cable jacket. Cat 5 cable contains eight conductors, arranged in four
twisted pairs, and terminated with an RJ45 type connector. In addition, there are restrictions on maximum
cable length for both 10 and 100 Mbits/second networks.
Capacity planning
Determining whether current solutions can satisfy future demands. Capacity planning includes evaluating
potential workload and infrastructure changes.
Checksum
A simple error-detection scheme in which each transmitted message is identified with a numerical value
based on the number of set bits in the message. The receiving station then applies a formula to the message
and checks to make sure the accompanying numerical value is the same. If not, the receiver can assume that
the message has been corrupted.

Class of Service
A term to describe treating different types of traffic with different levels of service priority. Higher priority
traffic gets faster treatment during times of switch congestion
CLI
Collision
A term used to describe two colliding packets in an Ethernet network. Collisions are a part of normal
Ethernet operation, but a sudden prolonged increase in the number of collisions can indicate a problem with
a device, particularly if it is not accompanied by a general increase in traffic.
Command Line Interface
CLI is a line-item interface for configuring systems. (It is one of the user interfaces for allowing
programmers to configure their system).
Common Open Policy Service Protocol
A proposed standard protocol for exchanging network policy information between a Policy Decision Point
(PDP) in a network and Policy Enforcement Points (PEPs) as part of overall Quality of Service (QoS) - the
allocation of network traffic resources according to desired priorities of service. The policy decision point
might be a network server controlled directly by the network administrator who enters policy statements
about which kinds of traffic (voice, bulk data, video, teleconferencing, and so forth) should get the highest
priority. The policy enforcement points might be router or layer 3 switches that implement the policy
choices as traffic moves through the network. Currently, COPS is designed for use with the Resource
Reservation Protocol (RSVP), which lets you allocate traffic priorities in advance for temporary
high-bandwidth requirements (for example, video broadcasts or multicasts). It is possible that COPS will be
extended to be a general policy communications protocol.

DHCP
Differentiated Services
Diffserv is a protocol for specifying and controlling network traffic by class so that certain types of traffic
get precedence - for example, voice traffic, which requires a relatively uninterrupted flow of data, might get
precedence over other kinds of traffic. Differentiated Services is the most advanced method for managing
traffic in terms of what is called Class of Service (CoS). Unlike the earlier mechanisms of 802.1P tagging
and Type of Service (ToS), Differentiated Services avoids simple priority tagging and depends on more

complex policy or rule statements to determine how to forward a given network packet. An analogy is made
to travel services, in which a person can choose among different modes of travel - train, bus, airplane -
degree of comfort, the number of stops on the route, standby status, the time of day or period of year for the
trip, and so forth. For a given set of packet travel rules, a packet is given one of 64 possible forwarding
behaviors - known as per hop behaviors (PHBs). A six-bit field, known as the Differentiated Services Code
Point (DSCP), in the Internet Protocol (Internet Protocol) header specifies the per hop behavior for a given
flow of packets. Differentiated Services and the Class of Service approach provide a way to control traffic
that is both more flexible and more scalability than the Quality of Service approach.
Diffserv
DNS
Short for Domain Name System (or Service), an Internet service that translates domain names into IP
addresses.
Because domain names are alphabetic, they're easier to remember. The Internet however, is really based on
IP addresses. Every time you use a domain name, therefore, a DNS service must translate the name into the
corresponding IP address. For example, the domain name www.example.com might translate to
198.105.232.4. The DNS system is, in fact, its own network. If one DNS server doesn't know how to
translate a particular domain name, it asks another one, and so on, until the correct IP address is returned.
Domain Name
A descriptive name for an address or group of addresses on the Internet. Domain names are of the form of a
registered entity name plus one of a number of predefined top level suffixes such as .com, .edu, .uk, etc. For
example, in the address mail.NETGEAR.com, mail is a server name and NETGEAR.com is the domain.
Dynamic Host Configuration Protocol
DHCP is a protocol for assigning dynamic IP addresses to devices on a network. With dynamic addressing,
a device can have a different IP address every time it connects to the network. In some systems, the device's
IP address can even change while it is still connected. DHCP also supports a mix of static and dynamic IP
addresses. Dynamic addressing simplifies network administration because the software tracks IP addresses
rather than requiring an administrator to manage the task. A new computer can be added to a network
without the hassle of manually assigning it a unique IP address.
E
EAP
Extensible Authentication Protocol is a general protocol for authentication that supports multiple
authentication methods.
EAP, an extension to PPP, supports such authentication methods as token cards, Kerberos, one-time
passwords, certificates, public key authentication and smart cards. In wireless communications using EAP, a
user requests connection to a WLAN through an AP, which then requests the identity of the user and

transmits that identity to an authentication server such as RADIUS. The server asks the AP for proof of
identity, which the AP gets from the user and then sends back to the server to complete the authentication.
EAP is defined by RFC 2284.
Endstation
A computer, printer, or server that is connected to a network.
Ethernet
A LAN specification developed jointly by Xerox, Intel and Digital Equipment Corporation. Ethernet
networks transmit packets at a rate of 10 Mbps.
F
Fast Ethernet
An Ethernet system that is designed to operate at 100 Mbps.
Fault isolation
A technique for identifying and alerting administrators about connections (such as those associated with
switch ports) that are experiencing congestion or failure, or exceeding an administrator-defined threshold.
Fast STP
Filtering
The process of screening a packet for certain characteristics, such as source address, destination address, or
protocol. Filtering is used to determine whether traffic is to be forwarded, and can also prevent unauthorized
access to a network or network devices.
Flow Control
The process of adjusting the flow of data from one network device to another to ensure that the receiving
device can handle all of the incoming data. This is particularly important where the sending device is
capable of sending data much faster than the receiving device can receive it. There are many flow control
mechanisms. One of the most common flow control protocols for asynchronous communication is called
xon-xoff. In this case, the receiving device sends a an “xoff” message to the sending device when its buffer
is full. The sending device then stops sending data. When the receiving device is ready to receive more data,
it sends an “xon” signal.
Forwarding
When a frame is received on an input port on a switch, the address is checked against the lookup table. If the
lookup table has recorded the destination address, the frame is automatically forwarded on an output port.

Internet Control Message Protocol
ICMP is an extension to the Internet Protocol (IP) that supports packets containing error, control, and
informational messages. The PING command, for example, uses ICMP to test an Internet connection.
Internet Group Management Protocol
IGMP is the standard for IP Multicasting on the Internet. IGMP is used to establish host memberships in
particular multicast groups on a single network. The mechanisms of the protocol allow a host to inform its
local router, using Host Membership Reports, that it wants to receive messages addressed to a specific
multicast group. All hosts conforming to Level 2 of the IP Multicasting specification require IGMP.
IP
IP Multicasting
Sending out data to distributed servers on the MBone (Multicast Backbone). For large amounts of data, IP
Multicast is more efficient than normal Internet transmissions because the server can broadcast a message to
many recipients simultaneously. Unlike traditional Internet traffic that requires separate connections for each
source-destination pair, IP Multicasting allows many recipients to share the same source. This means that
just one set of packets is transmitted for all the destinations.
Internet Protocol
The method or protocol by which data is sent from one computer to another on the Internet. Each computer
(known as a host) on the Internet has at least one IP address that uniquely identifies it among all other
computers on the Internet. When you send or receive data (for example, an e-mail note or a Web page), the
message gets divided into little chunks called packets. Each of these packets contains both the sender's
Internet address and the receiver's address. Any packet is sent first to a gateway computer that understands a
small part of the Internet. The gateway computer reads the destination address and forwards the packet to an
adjacent gateway that in turn reads the destination address and so forth across the Internet until one gateway
recognizes the packet as belonging to a computer within its immediate neighborhood or domain. That
gateway then forwards the packet directly to the computer whose address is specified.
Because a message is divided into a number of packets, each packet can, if necessary, be sent by a different
route across the Internet. Packets can arrive in a different order than they were sent. The Internet Protocol
just delivers them. It's up to another protocol, the Transmission Control Protocol (TCP) to put them back in
the right order. IP is a connectionless protocol, which means that there is no continuing connection between
the end points that are communicating. Each packet that travels through the Internet is treated as an
independent unit of data without any relation to any other unit of data. (The reason the packets do get put in
the right order is because of TCP, the connection-oriented protocol that keeps track of the packet sequence in
a message.) In the Open Systems Interconnection (OSI) communication model, IP is in Layer 3, the
Networking Layer. The most widely used version of IP today is IP version 4 (IPv4). However, IP version 6
(IPv6) is also beginning to be supported. IPv6 provides for much longer addresses and therefore for the
possibility of many more Internet users. IPv6 includes the capabilities of IPv4 and any server that can
support IPv6 packets can also support IPv4 packets.

LDAP
Lightweight Directory Access Protocol
A set of protocols for accessing information directories. LDAP is based on the standards contained within
the X.500 standard, but is significantly simpler. Unlike X.500, LDAP supports TCP/IP, which is necessary
for any type of Internet access. Although not yet widely implemented, LDAP should eventually make it
possible for almost any application running on virtually any computer platform to obtain directory
information, such as e-mail addresses and public keys. Because LDAP is an open protocol, applications
need not worry about the type of server hosting the directory.
Learning
The bridge examines the Layer 2 source addresses of every frame on the attached networks (called listening)
and then maintains a table, or cache, of which MAC addresses are attached to each of its ports.
Link-State
In routing protocols, the declared information about the available interfaces and available neighbors of a
router or network. The protocol's topological database is formed from the collected link-state declarations.
Load balancing
The ability to distribute traffic across various ports of a device, such as a switch, to provide efficient,
optimized traffic throughout the network.
Local Area Network
A communications network serving users within a limited area, such as one floor of a building. A LAN
typically connects multiple personal computers and shared network devices such as storage and printers.
Although many technologies exist to implement a LAN, Ethernet is the most common for connecting
personal computers and is limited to a distance of 1,500 feet. LANs can be connected together, but if
modems and telephones connect two or more LANs, the larger network constitutes what is called a WAN or
Wide Area Network.
Loop
An event that occurs when two network devices are connected by more than one path, thereby causing
packets to repeatedly cycle around the network and not reach their destination.

MDI/MDIX
In cable wiring, the concept of transmit and receive are from the perspective of the PC, which is wired as a
Media Dependant Interface (MDI). In MDI wiring, a PC transmits on pins 1 and 2. At the hub, switch,

MPLS
Multicast Backbone
The MBONE is a virtual network. It is layered on top of portions of the physical Internet to support routing
of IP multicast packets since that function has not yet been integrated into many production routers. The
network is composed of islands that can directly support IP multicast, such as multicast LANs like Ethernet,
linked by virtual point-to-point links called "tunnels". The tunnel endpoints are typically workstation-class
machines having operating system support for IP multicast and running the "mrouted" multicast routing
daemon.
Multicasting
To transmit a message to specific recipients across a network. A simple example of multicasting is sending
an e-mail message to a mailing list. Teleconferencing and videoconferencing also use multicasting, but
require more robust protocols and networks. Standards are being developed to support multicasting over a
TCP/IP network such as the Internet. These standards, IP Multicast and Mbone, will allow users to easily
join multicast groups. Note that multicasting refers to sending a message to a select group whereas
broadcasting refers to sending a message to everyone connected to a network. The terms multicast and
narrowcast are often used interchangeably, although narrowcast usually refers to the business model whereas
multicast refers to the actual technology used to transmit the data.
Multicast OSPF
With a MOSPF specification, an IP Multicast packet is routed based both on the packet's source and its
multicast destination (commonly referred to as source/destination routing). As it is routed, the multicast
packet follows a shortest path to each multicast destination. During packet forwarding, any commonality of
paths is exploited; when multiple hosts belong to a single multicast group, a multicast packet will be
replicated only when the paths to the separate hosts diverge. See “OSPF” on page 15 for more information.
Multiplexing
A function within a layer that interleaves the information from multiple connections into one connection.
Multi-Protocol Label Switching
An initiative that integrates Layer 2 information about network links (bandwidth, latency, utilization) into
Layer 3 (IP) within a particular autonomous system—or ISP—in order to simplify and improve IP-packet
exchange. MPLS gives network operators a great deal of flexibility to divert and route traffic around link
failures, congestion, and bottlenecks. From a QoS standpoint, ISPs will better be able to manage different
kinds of data streams based on priority and service plan. For instance, those who subscribe to a premium
service plan, or those who receive a lot of streaming media or high-bandwidth content can see minimal
latency and packet loss. When packets enter into a MPLS-based network, Label Edge Routers (LERs) give
them a label (identifier). These labels not only contain information based on the routing table entry (i.e.,
destination, bandwidth, delay, and other metrics), but also refer to the IP header field (source IP address),
Layer 4 socket number information, and differentiated service. Once this classification is complete and
mapped, different packets are assigned to corresponding Labeled Switch Paths (LSPs), where Label Switch

if necessary. Port mirroring can be managed locally or remotely. An administrator configures port mirroring
by assigning a port from which to copy all packets and another port where those packets will be sent. A
packet bound for or heading away from the first port will be forwarded onto the second port as well. The
administrator places a protocol analyzer on the port receiving the mirrored data to monitor each segment
separately. The analyzer captures and evaluates the data without affecting the client on the original port. The
monitor port may be a port on the same SwitchModule with an attached RMON probe, a port on a different
SwitchModule in the same hub, or the SwitchModule processor. Port mirroring can consume significant
CPU resources while active. Better choices for long-term monitoring may include a passive tap like an
optical probe or an Ethernet repeater.

Simple Network Management Protocol
SNMP is the protocol governing network management and the monitoring of network devices and their

protocol, which is now largely forgotten.
SNMPv2p (historic): For this version, much work was done to update the SNMPv1 protocol and the SMIv1,
and not just security. The result was updated protocol operations, new protocol operations and data types,
and party-based security from SNMPsec.
SNMPv2c (experimental): This version of the protocol is called community string-based SNMPv2. It is an
update of the protocol operations and data types of SNMPv2p, and uses community-based security from
SNMPv1.
SNMPv2u (experimental): This version of the protocol uses the protocol operations and data types of
SNMPv2c and security based on users.
SNMPv2* (experimental): This version combined the best features of SNMPv2p and SNMPv2u. (It is also
called SNMPv2star.) The documents defining this version were never published as RFCs.
SNMPv3 (proposed): This version of the protocol is a combination of user-based security and the protocol
operations and data types from SNMPv2p and support for proxies. The security is based on that found in
SNMPv2u and SNMPv2*, and updated after much review. The documents defining this protocol will soon
be published as RFCs.

client/server applications communicating over the Internet.
The TLS protocol is made up of two layers. The TLS Record Protocol ensures that a connection is private by
using symmetric data encryption and ensures that the connection is reliable. The second TLS layer is the
TLS Handshake Protocol, which allows authentication between the server and client and the negotiation of

Virtual Router Redundancy Protocol
VRRP specifies an election protocol that dynamically assigns responsibility for a virtual router to one of the
VRRP routers on a LAN. The VRRP router controlling the IP address(es) associated with a virtual router is
called the Master, and forwards packets sent to these IP addresses. The election process provides dynamic
fail-over in the forwarding responsibility should the Master become unavailable. This allows any of the
virtual router IP addresses on the LAN to be used as the default first hop router by end-hosts. The advantage
gained from using VRRP is a higher availability default path without requiring configuration of dynamic
routing or router discovery protocols on every end-host.
