Learning About the
User Interface
This section describes how to access the bridge/router user interface and provides
an overview of the menu-driven and command-line interfaces.
This section also includes the following information:
■
How to specify values, set members, or set addresses when using either the
menu-driven or command-line interface
■
How to use online help
Accessing the User To access the user interface or to modify the configuration of the NETBuilder
Interface bridge/router, use one of the following methods:
■
■
■
Access the bridge/router commands locally through the console port.
Establish a Telnet session with the bridge/router using security passwords.
Use a device (for example, a workstation) on the same extended network or
internetwork to access the bridge/router through the Telnet protocol.
NETBuilder software also supports outgoing Telnet.
The software supports TCP and UDP over Bigger Addresses (TUBA), which
means you can Telnet to the bridge/router using an IP address or an OSI
NSAP address from a PC or workstation. For more information about using
Telnet on a workstation, refer to the manual that accompanies the
workstation.
■
View and configure a subset of bridge/router parameters from a remote host
using SNMP. For information on preparing the bridge/router to run SNMP, refer
to Using NETBuilder Family Software.
After accessing the user interface, you need to decide whether to use the
menu-driven interface or the command-line interface.
Menu-Driven Versus After accessing the bridge/router user interface, you can issue a command in one
Command-Line Interface of two ways:
■
Use the menu-driven interface if you are unsure of the command syntax.
For more information about the MEnu command, refer to Reference for
NETBuilder Family Software. For information on how to use the menu-driven
interface, see the next section.
■
Enter the command at the system prompt if you know the exact syntax.
For information about the command line and rules for entering commands,

■
Choose a parameter and see the commands used with it.
Check the active and default values of a particular parameter.
Display the syntax of a particular parameter.
Enter the new value of a parameter.
To use the menu-driven interface, you must have Network Manager privilege.
When using the menu-driven interface, you cannot access some parameters; for
example, you cannot alter the number of lines on the screen, or change privilege
level. Accessing the NETBuilder bridge/router through the REMote command
requires the command-line interface.
To use the menu-driven interface, follow these steps:
1 Access the main menu by entering:
MEnu
The Main menu (Level 1) is displayed.
Depending on your software package, the number of services in your Main menu
may vary.
2 Select the desired service.
For example, selecting 1 from the Main menu (Level 1) display generates a menu
for the SYS Service.
3 Select the parameter you want to configure.
For example, if you select the NMPrompt parameter from the SYS Service menu
(Level 2) menu, information for that parameter is displayed.
The first part of the screen displays the value of the parameter; the second part
lists the commands you can choose. For information on help menus, refer to

NETBuilder family bridge/router guides and online help use upper- and lowercase
letters to distinguish the full form of commands and command syntax from the
abbreviated form. You can enter a command in abbreviated form by typing only
the uppercase portion. It does not matter whether you type the command in
upper- or lowercase letters.
Abbreviated Syntax
Abbreviated syntax is the shortest unambiguous abbreviation of a command,
parameter, or value that can be entered. You can enter the abbreviated form in
lower- or uppercase letters at the NETBuilder prompt.
Commands, parameters, and service names can be entered in abbreviated form.
Uppercase denotes the shortest unambiguous abbreviation of a command,
service name, or parameter.

Symbols
You may see a variety of symbols shown as part of the command syntax. These
symbols usually explain how to enter the command, and you do not type them as
part of the command itself. The exceptions to this rule are parentheses, the
hyphen, and the exclamation point, which you do type as part of the command.

Description
angle brackets < > Enclose a variable or value. You must specify the variable or value; for
example, in the syntax:
DELete -IP ADDRess <IP address>
you must supply an address for <IP address> when you enter the
command. Do not type the angle brackets.
square brackets[ ] Enclose an optional value or a list of optional arguments. One or more
values or arguments can be specified. For example, in the syntax:
SET PRIvilege = [User | NetMgr]
you can specify either User or NetMgr when you enter the command. Do
not type the square brackets.
parentheses ( )
Enclose a list of values that can be assigned to a single parameter. At least
one of them must be selected. You must type the parentheses and
separate the values with a comma if you are assigning more than one
value. For example, in the syntax:
SET CurrentPorts = ALL | (<port>, <port>)
you can specify two port numbers by enclosing them in parentheses and
separating them with a comma when you enter the command.

vertical bar |
Separates mutually exclusive items in a list, one of which must be entered.
For example, in the syntax:
SET ScreenLength = [None | <line>(6–100)]
you can specify either the word None or a number between 6 and 100
when you enter the command. Do not type the vertical bar.
ellipsis ...
Following a parameter name or value, indicates that one or more
additional arguments may be specified on the same command line. For
example, in the syntax:

...] [ANY]
you can specify multiple authorities (GENSER, SIOP, SCI, NSA, DOE, NONE)
when you enter the command. Do not type the ellipsis.
hyphen -
A letter preceded by a hyphen represents a command option. Also, when
you enter a service name as part of the command, you must precede the
service name with a hyphen. For example, in the command:
SETDefault -BRidge CONTrol = Bridge
You must include the hyphen with the service name BRidge when you
enter the command.
braces { }
Enclose a list of values, one of which must be entered. For example, in
the syntax:
SETDefault !<subaddr #> -Gateway SubAddrMap =
{(<IPaddr> | <PSAPaddr>) | None}
you must enter either an IP address, PSAP address, or the word None
when you enter the command. Do not type the braces.
exclamation point ! A number preceded by an exclamation point represents a port, virtual
port, or path number. For example, in the syntax:
SHow [!<port>] -DECnet CONFiguration
the exclamation point must be included before the port number when
you enter the command.
The exclamation point is also used to refer to a profile number. Refer to
the PROFile Service chapter in Reference for NETBuilder Family Software.

SETD -IP CONT = ([RO | NRO], [RSR | NRSR], [SL | NSL], [F | NF], [SEC
| NSEC],[FSB | NFSB], [FASB | NFASB])
The following command uses this abbreviated syntax to enable IP routing, packet
filtering, and security:
SETD -IP CONT = (RO, F, SEC)
Variations in Command Syntax
Each command has its own syntax. When a command is used for configuring
parameters, its syntax or values may change according to the parameter and
service. For example, the SETDefault command sets the NetMapTime parameter in
the SYS Service and the MaxAge parameter in the STP Service. In the following
example, the general syntax is followed by the syntax variations (different values
for different parameters) appropriate to each parameter:
SETDefault <parameter> = <value>
SETDefault -SYS NetMapTime = <number>(0 to 120 seconds)
SETDefault -STP MaxAge = <second> (6-40)
Entering Service Names in Command Lines
When you are configuring or displaying parameters that appear in more than one
service, you must provide a service name to distinguish them. You can enter the
service name in abbreviated form, but the name must be preceded by a hyphen.
For example, to indicate BRidge Service, type -BR.
Abbreviated service names are indicated in uppercase in this guide.
There are three exceptions:
■
If you have previously set the CurrentServices parameter to the desired service,
you do not need to enter the service name. The system prompt indicates the
current service if you set a single service with the CurrentServices parameter.
For information on using the CurrentServices parameter, refer to Reference for
NETBuilder Family Software.
■
■
Environment parameters do not have a service name. For descriptions of these
parameters, refer to Reference for NETBuilder Family Software.
You do not need to enter a service name when the parameter name is unique.
Determining the Display of Ports and Virtual Ports
You can control which ports are displayed in the output of the SHow and
SHowDefault commands by setting the CurrentPorts parameter. If you have a
bridge/router with several ports, for example a NETBuilder II bridge/router with
multiport I/O modules installed, you may want to limit the display to information
on certain ports instead of all ports. If you are interested only in displaying
information for port 2 and virtual port V3, as well as the paths mapped to these
ports, set the CurrentPorts parameter by entering:
SET CurrentPorts = (2, V3)
Now when you enter SHow and SHowDefault commands, only information for
port 2 and virtual port V3, and the paths mapped to these ports, is displayed.
If you have a NETBuilder II bridge/router with a multiport module installed, you
must enter its ports individually when setting the CurrentPorts parameter. For

CHAPTER 6: CONFIGURING BASIC SETTINGS
instance, if you have an Ethernet 2-Port 10BASE-FL module, the A and B ports are
distinct. If you specify port 1 with the CurrentPorts parameter, the software
assumes you mean port 1A. For information on port and path numbering
conventions for multiport modules, refer to Chapter 1 in Using NETBuilder Family
Software. For more information about the CurrentPorts parameter, refer to
Reference for NETBuilder Family Software.
The syntax convention for ports, virtual ports, and group ports is:
!<port>
For a port, <port> is a variable ID number, for example, !1. For a virtual port or
group port, <port> is the letter V followed by a variable ID number, for example,
!V1.
When you create a virtual port or group port, it functions in the same way as a
port. Unless otherwise specified, the term “port” refers to virtual ports and group
ports as well as ports. For more information on ports, virtual ports, and group
ports, refer to Chapter 1 in Using NETBuilder Family Software.
Using Aliases
To avoid entering lengthy commands, you can create an alias to represent any
command. To define an alias, use:
ADD -SYS ALias <alias name> <arguments…>
For example, if you use the SHow -SYS NetMAP command often, create an alias
called ntmap by entering:
ADD -SYS ALias ntmap SHow -SYS NetMAP
When you want to display the network map, at the bridge/router prompt enter:
ntmap
For more information about aliases, refer to Reference for NETBuilder Family
Software.
Command History Substitution
The bridge/router “remembers” the last 10 commands you enter. To display a list
of these commands, at the bridge/router prompt enter:
SHow History
For more information refer to Reference for NETBuilder Family Software. Each
command in the display is numbered. To repeat any of the commands, use the
event designator, represented by an exclamation point (!).
You can use history substitution with the following options:
!!
Repeats the previous command.
!<n>
Repeats the command numbered <n>. For example,
entering !100 repeats the command numbered 100. If
you know the command number, you do not need to
display it first.

Learning About the User Interface
6-9
!-<n>
Repeats the command whose number is the current
command number minus <n>. The current command
number is shown on the screen preceding the
bridge/router prompt. For example, if the current
command is 100 and <n> is 2, command number 98 is
repeated.
!<string>
Repeats the most recent command that starts with the
variable <string>. The SHow History command might
display:
166 setdefault !1 -path control = enabled
167 show -path configuration
168 show history
169 set screenlength = 23
170 setdefault -bridge control = bridge
171 show statistics ?
If you enter !SETD at the prompt, the most recent
occurrence of the SETDefault command is executed:
setdefault -bridge control = bridge
!?<string>
Repeats the most recent command containing <string>.
In the preceding example, if you enter !?stat, the
command show statistics ? (number 171) is executed.
You can also repeat a previous command with
modifications by using the syntax described next.
^<string1>
Repeats the most recent command that contains
^<string1>^<string2> <string1>. If <string2> is specified, it replaces <string1>
in that command. For example, suppose you made a
typing mistake when you entered the following
SETDefault command:
seed welcomestring = “You are talking to the 3Com NETBuilder”
To repeat the command with the correct spelling of SETD,
you do not need to reenter the entire command. Enter:
^seed^setd
The following command is then displayed and executed:
setd welcomestring = “You are talking to the 3Com NETBuilder”
Privilege Level
The privilege level determines which commands and parameters a user can access.
The network manager must set the Network Manager password and the User
password to be the same in order to provide equal levels of security. If only the
Network Manager password is set, any other user receives User level privileges.
You can change the privilege level with the SET PRIvilege command. For more
information, refer to Reference for NETBuilder Family Software.
Command-Line Parameter values, set members, and addresses can be expressed either as numbers
Parameter Attributes or as text. This section provides guidelines for specifying numeric values, strings,
and addresses. For details on the values permitted for each parameter, refer to

Addresses Two types of addresses can be assigned: media addresses for #311040800245,
Ethernet, FDDI, token ring, and wide area protocols (SMDS,
X.25, Frame Relay) and network layer addresses.
129.213.24.30
The SET, SETDefault, and SYSgen commands require both parameter names and
parameter values. The parameter name is followed by an equal sign (=) and a value.
Spaces are permitted, but not required, before and after the equal sign, for
example:
SETDefault -SYS ScreenLength = 30
The ADD and DELete commands also require both parameter names and parameter
values. These commands modify sets of objects. No equal sign precedes the value
that is added or deleted as a set member, for example:
ADD -IP ADDRess 10.0.0.1 %080002001234
Numeric Values
To assign a hexadecimal value to a parameter, precede the number with a percent
sign (% ). Alphabetic characters can be entered in upper- or lowercase letters.
To assign a decimal number, type the number without any preceding symbol.
Names
To assign a name, type the name in the command. Names, unlike strings, do not
require quotation marks; however, the character length of the name may be
limited.
Strings
String values fall into two categories: single characters and variable-length strings.

A few characters have special meaning to the bridge/router and must be preceded
by a backslash (\) in string text to prevent them from being misinterpreted. These
symbols are the apostrophe ('), backslash (\), caret (^), and quotation mark (“). For
example, to include an apostrophe in string text, enter a backslash followed by an
apostrophe (\'). To include a backslash (\) in string text, enter two backslashes (\\).
The first backslash prevents the bridge/router from treating the second as a
special character.
When specifying AppleTalk zone strings, you can use the extended AppleTalk
ASCII character set. For more information, refer to Using NETBuilder Family
Software.
You can assign a string to the PATH NAme parameter, and use this string as an
instance identifier. For example, you can assign the name “testnet” to path 2 by
entering:
SETDefault !2 -PATH NAme = “testnet”
In subsequent path-specific commands, you can substitute the path name for !2.
For example, if you want to set the connector type on path 2 after assigning a
name to this path, enter:
SETDefault !testnet -PATH CONNEctor = RS232
This same feature is available for port-specific commands. You can assign a name
to a port and then substitute the port name for !<port> in subsequent commands.
To assign a name to a port, use:
SETDefault !<port> -PORT NAme = “<string>”
For more information on the NAme parameter, refer to Reference for NETBuilder
Family Software.
Port and Path Naming Restrictions
Port and path names are subject to the following restrictions:
■
■
■
■
The name string can contain a maximum of eight characters, the first of which
must be alphabetic.
No blank spaces are allowed. The only nonalphanumeric characters allowed are
the asterisk (*), underscore (_), period (.), and hyphen (-).
Two ports or two paths cannot have the same name, but a port name can be
the same as a path name.
Alphabetic characters are stored and displayed as entered. Names are
case-insensitive when compared with previously entered names. For example,
port2 and PORT2 are evaluated as the same name.
ISDN-Related Syntax The syntax for some parameters is different for built-in Integrated Services Digital
Variation Network (ISDN) interfaces. The syntax variation for these parameters is presented
in Reference for NETBuilder Family Software in the following format:
For non-ISDN interfaces SETDefault !<path> -PATH remoteDialNo = “<string>”
SHow [!<path> | !*] -PATH remoteDialNo
SHowDefault [!<path> | !*] -PATH remoteDialNo
For built-in ISDN interfaces SETDefault !<connectorID.channelID> -PATH remoteDialNo = “<string>”

SHowDefault [!<connectorID.channelID> | !<connectorID>.*] -PATH
remoteDialNo

CHAPTER 6: CONFIGURING BASIC SETTINGS
The syntax variation for non-ISDN interfaces applies to local area network (LAN) and
data terminal equipment (DTE) interfaces.
NETBuilder software menus and help strings do not display the syntax variation for
ISDN interfaces.
The variation in syntax is caused partially by the different path-numbering
convention used for ISDN. For information, refer to Using NETBuilder Family
Software. Special parameter values related to built-in ISDN interfaces can also cause
a variation in syntax.
Some parameters in ISDN-specific software are connector-related and require that
you specify a connector number (<connectorID>), for example, 2. Other parameters
are channel-related and require that you specify both a connector and a channel
number (<connectorID.channelID>), for example, 2.1. When you specify both a
connector and a channel number, you must separate them with a decimal point.
If you do not specify a channel number in a command that requires both a
connector and a channel number, the software assumes the first channel associated
with the connector. For example, if you specify connector number 2 when the syntax
requires that you to specify both a connector and a channel number, the software
assumes you mean 2.1.
To specify all channels associated with a connector, specify the connector number, a
decimal point, and an asterisk, for example, 2.*
Address Formats The following summary describes media addresses and network layer addresses the
bridge/router uses and their formats. For detailed information on protocol-specific
addressing, refer to Reference for NETBuilder Family Software.
Media Addresses
MAC
Contains 12 hexadecimal digits preceded by a percent sign (% ).
The NETBuilder II bridge/router has a media access control (MAC)
address (physical) for each LAN interface (Ethernet, FDDI, or token
ring), for each HSS interface, and for the CEC module.
The MAC address and the network identifier constitute a network
address, which is the only address used by Xerox Network Systems
(XNS) and Internetwork Packet Exchange (IPX) routers. IP routers
have both MAC addresses for their LAN interfaces and Internet
addresses for their configured ports. Internet addresses are
Each MAC address is assigned by 3Com. A MAC address can be
displayed by entering:
SHow -SYS ADDRess
The following is an example of a MAC address:

Learning About the User Interface 6-13
Frame Relay Requires an address called a Data Link Connection Identifier (DLCI).
DLCIs are assigned by the appropriate authority at subscription
time. A DLCI follows an at sign (@) and can range from 1 through
1022 decimal. The DLCI identifies a virtual circuit on the Frame
Relay network, and is used by the local bridge/router to send a
packet to a router on the other end of the circuit. The following is
an example of a Frame Relay address:
@22
In the standard (local) addressing convention, the DLCI number has
only local significance; a duplicate number can be used by other
bridge/routers. In the global addressing convention, identifiers used
throughout the Frame Relay network are unique, and all traffic to a
node has the same destination DLCI number.
ATM
Consists of an 8-bit virtual path identifier (VPI) and a 16-bit virtual
circuit identifier (VCI), usually represented in VPI.VCI format, where
VPI is a decimal number between 0 and 255 and VCI is a decimal
number between 0 and 65,535. The following is an example of an
Asynchronous Transfer Mode (ATM) address:
107.44
Some vendors’ DSUs require an ATM address that consists of a 0-bit
VPI and a 10-bit VCI. In this case, the 10-bit VCI maps directly to a
Frame Relay DLCI.
SMDS
There are two types of Switched Multimegabit Data Service (SMDS)
addresses: individual addresses, for unicast traffic, and group
addresses, for multicast traffic. An individual address routes data to
a unique node. Packets sent to a group address are delivered to all
nodes that share that address. Both types of address begin with a
dollar sign. They are distinguished by the first or control digit:
hexadecimal C for an individual address and hexadecimal E for a
group address. Each address has 15 decimal digits following the
control digit and resembles a telephone number. The software
automatically right-pads shorter addresses with hexadecimal F to
the full length. The following are examples of individual and group
SMDS addresses:
C14085551212FFFF
E14085551234FFFF
Individual Address
Group Address
X.25
Consists of up to 15 decimal digits and can vary in length. The
address looks similar to a telephone number and is preceded by a
pound sign (#). An X.25 address is also referred to as a data
terminal equipment (DTE) address.
When a device is attached to a public data network (PDN), the
network provider assigns it an X.25 address or an international data
number (IDN). The first four digits indicate the country and PDN to
which the device is attached. The remaining digits represent a
unique device address determined by the network provider. The
following is an example of an X.25 address:
#311041503333

CHAPTER 6: CONFIGURING BASIC SETTINGS
ISDN
An ISDN address is a phone number provided by your
telecommunications carrier. It can include a dial prefix, country
code, area code, and phone number. It can consist of a maximum
of 30 characters. If you create a subaddress, you must separate the
phone number and the subaddress with a semicolon (;). The
subaddress can be composed of a maximum of 20 characters.
The following is an example of a valid ISDN address, including
a subaddress:
011122134567000;200
For complete information on ISDN addresses, refer to Using
NETBuilder Family Software.
Netw ork Layer Addresses
AppleTalk
Consists of the network number and node ID. Each AppleTalk node
address is unique throughout the AppleTalk Internet. For details on
assigning an AppleTalk address, refer to Reference for NETBuilder
Family Software. The following is an example of an AppleTalk
address:
4.23
DECnet
Consists of an area address and a node address. The area number
identifies the area to which the router belongs. Enter an area
number between 1 and 63. The node number assigned to the router
must be unique within the area. Enter a node number between 1
and 1,023. For details on assigning a DECnet address, refer to
Reference for NETBuilder Family Software. The following is an
example of a DECnet address:
1.15
Internet
Also known as an IP address. It consists of up to 12 decimal digits
arranged in four three-digit fields separated by periods, as shown in
the following format:
xxx.xxx.xxx.xxx
Leading zeros can be omitted. For example, the following addresses
are the same:
010.002.002.001
10.2.2.1
An Internet address is required for:
■
■
■
A bridge/router port to perform IP routing
The bridge/router to be accessed via Telnet
The bridge/router to respond to the PING command from
another host
■
The bridge/router to participate in SNMP-based network
management
An address includes both a network number and a host number. The
actual format of these numbers varies depending on the class of
address being designated. Address class is determined by the value
in the first octet of the address.

IPX
Leading zeros can be omitted. Consists of an ampersand (&) followed
by a network address, which contains eight hexadecimal digits,
followed by the MAC address.
You may need to enter an IPX address when using the bridge/router
for IPX routing. The network address uniquely distinguishes one IPX
network from all other IPX networks. The following example
addresses are the same:

VIP
A VINES Internet Protocol (VIP) address is globally unique, fixed, and
permanent for servers and routers only. Each node has a two-field,
48-bit Internet address, which is derived from the 32-bit VINES
network number and the 16-bit subnetwork number.
The Internet address has eight hexadecimal digits (VIP network ID)
and four hexadecimal digits (subnetwork ID) separated by a colon (:).
The Internet address (logical network) is independent of any data link

Storing Configuration Parameter Values 6-17
For more information on IP configuration, refer to Reference for NETBuilder Family
Software.
4 Enable IP routing by entering:
SETDefault -IP CONTrol = RO
5 Enable a routing protocol. For example, to enable RIP use:
SETDefault !<port> -RIPIP CONTrol = (Listen, Talk)
This step is optional.
6 Ensure your configuration by verifying that the bridge/router can access other
devices on the network, use:
PING <IP address>
where <IP address> is the IP address of another device on the network.
Storing Configuration
Parameter Values
Configuration parameters are stored in flash memory or on the disk of another
server (for example, the TFTP/FTP server that boots the bridge/router). In this
guide, the term “disk” refers to either the local flash memory drive or the hard
disk on another server.
When the bridge/router is booted, it copies configuration parameters from the
disk to memory. Parameter values on the disk are default values and values in
memory are active values. You can alter the default and active values with the
SETDefault and SET commands. For more information, refer to Reference for
NETBuilder Family Software.
When the new value of a parameter takes effect depends on whether its active
value has been changed. Some commands change the active value only, some
change the default value, and some change both. If you display the parameter
after modifying it and see the new value, the new value has taken effect
immediately. If a command changes only the default value, the new value takes
effect only after reboot. In this guide, if the description does not specify when the
new value of a parameter takes effect after being enabled or disabled, it is
effective immediately after it is set.
Obtaining Netw ork
Manager Privilege
Level
Before changing the Network Manager password, you must obtain Network
Manager privilege.
To display or change the privilege level, follow these steps:

the privilege level from User to Network Manager:
SET PRIvilege = NetMgr
The following prompt is displayed:
Password:
3 Press the Return key.
A null string is entered, which is the default password.
After obtaining Network Manager privilege, proceed to the next section to change
the Network Manager password.
Changing the
Passw ord
Changing the Network Manager password prevents unauthorized users from
accessing the bridge/router. You should change the password immediately after you
log on for the first time.
The privilege level determines which commands and parameters a user can access.
Each level has its own password. You must set the Network Manager password and
the User password to be the same in order to provide equal levels of security. If only
the Network Manager password is set, any other user receives User level privileges.
Users with NetMgr privileges can lower their privileges without a password. Users
with User privileges cannot raise their privileges. To raise privileges after lowering
them, you must enter the password again.
The Network Manager password must be set before the User password. The User
password must be cleared before the Network Manager password.
To change the password, follow these steps:
1 At the NETBuilder prompt (NETBuilder #), enter:
SysPassWord
When a menu is displayed, Select 1, Set Network Manager Privilege Password.
2 Enter the new Network Manager password. Retype it when prompted to do so.
You are returned to the SysPassWord menu.
3 Enter 2.
4 Enter the new User password and retype it when prompted to do so.
5 Press the Return key to exit the SysPassWord menu and return to the NETBuilder
prompt (NETBuilder #).
Go to the next section to set the time and date on the system.
Setting the Time and
Date
To set the time and date on your system, use:
SET -SYS DATE = YY/MM/DD HH:MM[:ss]
For example, to set the date and time to January 10, 1995, 9:40 a.m., enter:
SET -SYS DATE = 1995/1/10 09:40

Information
As system administrator, you can set the system name, location, and system
contact so that other system administrators can contact you for information. If you
are planning to use SNMP, you must set the system administrator information;
otherwise, these settings are optional.
Before performing the procedure, you need to decide on or obtain the following
information:
■
■
■
System name
System location
System contact person and phone number
To set system administrator information, follow these steps:
1 Specify a name for the node, using:
SETDefault -SYS SysNAMe = “<string>”
For example, to set the bridge/router name as “Sales.SanJose,” enter:
SETDefault -SYS SysNAMe = “Sales.SanJose”
The system name can contain no more than 255 characters. The default value is
“ “ (null string).
2 Specify the system location, using:
SETDefault -SYS SysLOCation = “<string>”
For example, to set the system location as “SecondFloor.Lab,” enter:
SETDefault -SYS SysLOCation = “SecondFloor.Lab”
The system location can contain no more than 255 characters. The default value is
“ “ (null string).
3 Specify a string that identifies the contact person managing the bridge/router,

Assigning Internet
Addresses
This section describes how to assign one or more Internet addresses to the system
using the NETaddr parameter in the IP Service. Before you assign an Internet
address, you must determine:

a unique Internet address.
■
■
Whether you want to use the system as a bridge, a router, or a bridge/router.
Whether you need subnet addressing.

Addresses to a Bridge participate in network management and to be accessible from other devices
through Telnet or the SNMP.
When assigning an Internet address to an entire bridge, assign the address to
port 0 using:
SETDefault !0 -IP NETaddr = <IP address>
An Internet address assigned to port 0 is considered an Internet address for the
entire bridge.
The following example illustrates how to assign an Internet address to a bridge.

network 10. The IP host on Network A has an Internet address 10.0.0.1, and the
one on Network B has an Internet address 10.0.0.2. The bridge forwards packets
between these segments. To allow communication between the hosts and the
bridge, ports 1 and 2 must reside on the same network. Assigning the same
network number to two or more bridge ports is prohibited, so you must assign the
address to the entire bridge, entering a command similar to the following:

Using NETBuilder Family Software.
Setting Up the Simple
Netw ork Management
Protocol
The NETBuilder II bridge/router participates in different types of network
management activities. Most management activities require configuration because
they are disabled by default. The bridge/router manages networks in the following
ways:
■
■
■
Configuring and monitoring from a UNIX or Windows network management
station using Transcend Enterprise Manager
Remote upgrade management using the NETBuilder Remote Upgrade
Management Utilities supplied on CD-ROM with every NETBuilder release
Building network maps (netmaps)
This guide does not describe in detail how to set up the SNMP Service. Refer to
Using NETBuilder Family Software and Reference for NETBuilder Family Software
for more information.
SNMP allows you to modify and display some NETBuilder parameters from a
network management station. You do not need to attach a terminal to the
bridge/router console port to change its configuration. To implement SNMP, follow
specifications in RFC 1155, RFC 1157, and RFC 1213. System parameters
described in RFC 1213 and 3Com extended parameters can be accessed from the
host.
Download from Www.Somanuals.com. All Manuals Search And Download.
NETBuilder Security 6-23
Modifying SNMP To enable SNMP read/write access, you need to modify two parameters in the
Parameters SNMP Service: COMmunity and MANager.
The COMmunity parameter is an SNMP Service parameter that modifies the list of
communities. For information on how to use the COMmunity parameter, refer to
Using NETBuilder Family Software and to Reference for NETBuilder Family
Software.
By default, the community name “ANYCOM” exists with read access to the
management information base (MIB) variables and allows unrestricted access to
the bridge/router. To ensure that access is available only to the proper system
administrator, 3Com recommends that you delete the “ANYCOM” community
name, and add the appropriate community string and the IP address of the
manager.
To modify SNMP parameters, follow these steps:
1 Delete the default community string “ANYCOM” by entering:
DELete -SNMP COMmunity “ANYCOM”
2 Configure at least one new community string with read/write access.
For example:
ADD -SNMP COMmunity “private” TRiv RW AL1
3 Add other community strings with read-only access as required.
For example:
ADD -SNMP COMmunity “public” TRiv RO AL1
4 Create a new manager with read/write access to the NETBuilder bridge/router. For
security reasons, limit the number of network management stations.
For example:
ADD -SNMP MANager “private” 129.213.224.1 255.255.0
5 Enable the SNMP service by entering:
SETDefault -SNMP CONTrol = (Manage, Trap)
NETBuilder Security
NETBuilder security can be obtained many ways including limiting the access to a
particular network or by limiting the access to certain files. Limiting access to a
particular network can be accomplished by building Internet firewalls. Limiting
access to particular files can be accomplished by using certain commands and
parameters.
Building Firew alls for A firewall allows users inside a private network to have outbound access, while
Security restricting outside users from inbound access. For more conceptual information
about firewall and its capabilities, and details on how to configure firewalls, refer
to Using NETBuilder Family Software. For a description and syntax of the various
firewall service parameters, refer to Reference for NETBuilder Family Software.

Booting from a
TFTP/FTP Server
If you do not have a flash memory drive or want to manage the software for one
or more bridge/routers on a centralized server, you can boot from a Trivial File
Transfer Protocol (TFTP) server. Configuration files can be accessed from the same
workstation running a File Transfer Protocol (FTP) server program.
Network boot is not supported by the NETBuilder II bridge/routers with the DPE
modules installed.
When you set up your NETBuilder bridge/router for network boot, you must
configure your bridge/router to boot from a particular server by specifying the IP
address of that server to the bridge/router. If you do not want to specify a
particular server, you may configure your NETBuilder II bridge/router to use BOOTP,
which discovers available TFTP servers on the local network by broadcasting
BOOTP request packets. For more information about BOOTP, refer to Reference for

WARRANTIES EXCLUSIVE
LIMITATION OF LIABILITY
GOVERNING LAW
IF A 3COM PRODUCT DOES NOT OPERATE AS WARRANTED ABOVE, CUSTOMER’S SOLE REMEDY FOR BREACH OF THAT

FULL EXTENT ALLOWED BY LAW, THE FOREGOING WARRANTIES AND REMEDIES ARE EXCLUSIVE AND ARE IN LIEU OF ALL
OTHER WARRANTIES, TERMS, OR CONDITIONS, EXPRESS OR IMPLIED, EITHER IN FACT OR BY OPERATION OF LAW,
STATUTORY OR OTHERWISE, INCLUDING WARRANTIES, TERMS, OR CONDITIONS OF MERCHANTABILITY, FITNESS FOR A
PARTICULAR PURPOSE, AND SATISFACTORY QUALITY. 3COM NEITHER ASSUMES NOR AUTHORIZES ANY OTHER PERSON

RESELLER HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES, AND LIMITS ITS LIABILITY TO REPAIR,
REPLACEMENT, OR REFUND OF THE PURCHASE PRICE PAID, AT 3COM’S OPTION. THIS DISCLAIMER OF LIABILITY FOR
DAMAGES WILL NOT BE AFFECTED IF ANY REMEDY PROVIDED HEREIN SHALL FAIL OF ITS ESSENTIAL PURPOSE.
Some countries, states, or provinces do not allow the exclusion or limitation of implied warranties or the limitation of
incidental or consequential damages for certain products supplied to consumers or the limitation for personal injury, so the
above limitations and exclusions may be limited in their application to you. This warranty gives you specific legal rights
which may vary depending on local law.
