Learning About the User Interfaces
19
Accessing the User To access the user interface or to modify the configuration of the bridge/router or
Interface tunnel switch, use one of the following methods:
■
Access the bridge/router commands locally through the console port.
■
Establish an HTTP session with the bridge/router using the Web Link
application.
■
■
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.
Enterprise OS 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, see 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, see
Using Enterprise OS Software.
Web Link Versus After accessing the bridge/router user interface, you can issue a command in one
Menu-Driven Versus of three ways:
Command-Line Interface
■
Use the Web Link application if you are unsure of the command syntax and you
have a compatible web-based browser on your network management station.
■
Use the menu-driven interface if you are unsure of the command syntax.
For more information about the MEnu command, see Reference for
Enterprise OS 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, see
The syntax for each command and parameter is described in Reference for
Enterprise OS Software.
Using the Web Link To log onto and configure a bridge/router using Web Link, follow these steps:
Application
1 Install the hardware and install all cables.
3 Set up your management workstation with a valid IP address.
To communicate with the bridge/router or tunnel switch, the IP address of the
management station should be an unused IP address in the range 10.1.0.2 -
10.1.255.254; subnet mask 255.255.0.0.
Once your management station possesses a valid IP address, the Web Link
application can be opened in the web browser running on the management
station.
4 Point your browser at the bridge/router interface IP address.
You are prompted to enter a user name and password.

values or a list of optional arguments.
Do not enter the square brackets.
NETBuilder bridge/router or PathBuilder switch 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 Enterprise OS prompt.

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.
Table 3 Command Syntax Symbols

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 |
ellipsis ...
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.
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:
ADD !<port> -IP SecAuthIn <authority> [<authority> ...]
[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 see a profile number. See the
PROFile Service chapter in Reference for Enterprise OS Software.
Full and Abbreviated Syntax Examples
The following examples show the full form first, followed by the abbreviated
command syntax.
The full-form command syntax:
ADD !<port> -NRIP AdvToNeighbor <network>%<mac address> [...]
can be abbreviated to:
ADD !<port> -NRIP ATN <network>%<mac address> [...]
Replacing the variables in this abbreviated command syntax with values might
specify, for example, that a neighbor on port 2, network number &10, with
address % 080002030ef2, receives RIP and SAP updates:
ADD !2 -NRIP ATN &10%080002030ef2
The full-form command syntax:
SETDefault -IP CONTrol = ([ROute | NoROute], [RelaySrcRoute |
NoRelaySrcRoute], [SplitLoad | NoSplitLoad], [Filtering | NoFiltering],
[SECurity | NoSECurity], [FwdSubnetBcast | NoFwdSubnetBcast],
[FwdAllSubnetBcast | NoFwdAllSubnetBcast])
can be shortened by abbreviating it to:
SETD -IP CONT = ([RO | NRO], [RSR | NRSR], [SL | NSL], [F | NF], [SEC |
NSEC],[FSB | NFSB], [FASB | NFASB])

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, see Reference for
Enterprise OS Software.
■
■
Environment parameters do not have a service name. For descriptions of these
parameters, see Reference for Enterprise OS 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
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, see Chapter 1 in Using Enterprise OS
Download from Www.Somanuals.com. All Manuals Search And Download.
26
CHAPTER 4: CONFIGURING BASIC SETTINGS
Software. For more information about the CurrentPorts parameter, see Reference
for Enterprise OS 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, see
Chapter 1 in Using Enterprise OS 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, see Reference for Enterprise OS 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 see Reference for Enterprise OS 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.
!-<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.

27
!<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, see Reference for Enterprise OS Software.
Command-Line Parameter values, set members, and addresses can be expressed either as numbers

Some parameter values can be set to user-defined strings,
ranging from a single character (written as char) to a
multicharacter string (written as string).
“A,” “B,”

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.

Characters in a string are case-sensitive. For example, “ABC” is different from “abc.”
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, see Using Enterprise OS 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, see Reference for Enterprise OS
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 Enterprise OS 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>”
SHow [!<connectorID.channelID> | !<connectorID>.*] -PATH remoteDialNo
SHowDefault [!<connectorID.channelID> | !<connectorID>.*] -PATH
remoteDialNo

CHAPTER 4: CONFIGURING BASIC SETTINGS
The syntax variation for non-ISDN interfaces applies to local area network (LAN)
and data terminal equipment (DTE) interfaces.
Enterprise OS 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, see Using Enterprise OS 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, see Reference for Enterprise OS 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 main processor 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:

Learning About the User Interfaces
31
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/router or tunnel switches. 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 4: 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, see Using
Enterprise OS 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, see Reference for Enterprise OS
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, see Reference
for Enterprise OS 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:

Area address (variable length)
System ID (six octets)
N-selector (one octet)
The system ID and N-selector are the last seven octets of the MAC

For more information on the OSI addressing scheme, OSI routing
domains, and area addresses, see Using Enterprise OS Software.
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
layer address assigned to a node on a physical medium. The

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 or tunnel
switch). 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, see Reference for Enterprise OS
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

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:
1 To determine the current privilege level, enter:
SHow PRIvilege
If the following message is displayed, you already have Network Manager privilege:
PRIvilege = NetMgr
If the following message is displayed, go to step 2:
PRIvilege = User
You also can determine the privilege level from the Enterprise OS prompt. The
following prompt is displayed at the Network Manager privilege level:
Enterprise OS #
The following prompt is displayed at the User privilege level:
Enterprise OS >
2 If you are currently at User privilege level, enter the following command to change
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 or tunnel switch. 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.

CHAPTER 4: CONFIGURING BASIC SETTINGS
To change the password, follow these steps:
1 At the Enterprise OS prompt (Enterprise OS #), 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
Enterprise OS prompt (Enterprise OS #).
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
The NETBuilder II bridge/router contains a real-time clock, so you do not need to
set the date after each reboot to keep it correct.
For more information on these parameters, see Reference for Enterprise OS
Software. Proceed to the next section to enter system administrator information.
Setting System
Administrator
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”

37
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 or
tunnel switch, using:
SETDefault -SYS SysCONtact = “<string>”
For example, to specify John Smith as the system contact and a number to reach him,
enter:
SETDefault -SYS SysCONtact = “John Smith (408) 555-1111”
The system contact string can contain no more than 255 characters. The default
value is “ “ (null string). Users can obtain this information by entering:
SHow -SYS SysCONtact
Proceed to the next section to assign an Internet address.
4 Specify a banner string to be displayed by the bridge/router or tunnel switch:
The banner string can contain no more than 110 characters. The default value is “ “
(null string). Use:
SETDefault -SYS BannerString = “<string>
The SYStem service BannerString parameter allows you to input a text string that is
used as a information message for a bridge/router or tunnel switch. The string can be
up to 110 characters long and is displayed immediately prior to the word
“NetLogin:” when you are connecting to a bridge/router console. The banner string
is suppressed if the InterAction parameter is set to NoLOGin. This banner string is
redisplayed with each login retry.
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:
■
■
■
Whether you want your network to connect to the Internet, and how to obtain a
unique Internet address.
Whether you want to use the system as a bridge, a router, a bridge/router or a
tunnel switch.
Whether you need subnet addressing.
Enterprise OS Software.
Assigning Internet Even though a bridge does not route IP traffic, it needs an Internet address to
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.

CHAPTER 4: CONFIGURING BASIC SETTINGS
The following example illustrates how to assign an Internet address to a bridge.
a bridge. Hosts A and B are two hosts belonging to the same IP network, 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:
SETDefault !0 -IP NETaddr = 10.0.0.3

CHAPTER 4: CONFIGURING BASIC SETTINGS
If you do not plan to be connected to the Internet, you can assign network
addresses on your own. However, if you plan on accessing the Internet in the
future, you may want to apply for an Internet network address so you will not
have to change network addresses when you make the connection.
For additional information on Internet addresses and subnets, see Using
Enterprise OS Software.
Setting Up the Simple
Netw ork
Management Protocol
The 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 Enterprise OS Remote Upgrade
Management Utilities supplied on CD-ROM with every Enterprise OS release.
Building network maps (netmaps).
This guide does not describe in detail how to set up the SNMP Service. See Using
Enterprise OS Software and Reference for Enterprise OS Software for more
information.
SNMP allows you to modify and display some Enterprise OS 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.
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, see
Using Enterprise OS Software and to Reference for Enterprise OS 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 or tunnel switch. 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.
Download from Www.Somanuals.com. All Manuals Search And Download.
NETBuilder Security
41
For example:
ADD -SNMP COMmunity “public” TRiv RO AL1
4 Create a new manager with read/write access to the bridge/router or tunnel
switch. 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, see
Using Enterprise OS Software. For a description and syntax of the various firewall
service parameters, see Reference for Enterprise OS Software.
Security Commands and To make sure that some designated files are accessible only to the system
Parameters administrator, use the following commands and parameters:
■
NetAccess
This parameter is a SYS Service parameter that determines how a bridge/router
can be accessed from another device on the network. For information on how
to use the NetAccess parameter, see Using Enterprise OS Software and
Reference for Enterprise OS Software.
■
■
SysPassWord
This command brings up a menu allowing you to specify the password for the
Network Manager and User privilege levels. For information on how to use the
SysPassWord command, see Reference for Enterprise OS Software.
RemoteManager
This parameter is a SYS Service parameter that specifies the Internet addresses
of devices that can connect to the bridge/router through the REMote
command. For information on how to use the RemoteManager parameter, see
Using Enterprise OS Software and Reference for Enterprise OS Software.
■
COMmunity
This parameter is an SNMP Service parameter that modifies the list of
communities. For information on how to use the COMmunity parameter, see
Using Enterprise OS Software and Reference for Enterprise OS Software.

If a product does not operate as warranted above during the applicable warranty period, 3Com shall, at its option and expense,
repair the defective product or part, deliver to Customer an equivalent product or part to replace the defective item, or refund
to Customer the purchase price paid for the defective product. All products that are replaced will become the property of

warranty or the remainder of the initial warranty period, whichever is longer.
SOFTWARE

specifications therefor for a period of ninety (90) days from the date of purchase from 3Com or its authorized reseller. 3Com
warrants the media containing software against failure during the warranty period. No updates are provided. 3Com’s sole
obligation with respect to this express warranty shall be (at 3Com’s discretion) to refund the purchase price paid by Customer
for any defective software products, or to replace any defective media with software which substantially conforms to applicable
3Com published specifications. Customer assumes responsibility for the selection of the appropriate applications program and
associated reference materials. 3Com makes no warranty or representation that its software products will meet Customer’s
requirements or work in combination with any hardware or applications software products provided by third parties, that the
operation of the software products will be uninterrupted or error free, or that all defects in the software products will be
corrected. For any third party products listed in the 3Com software product documentation or specifications as being
compatible, 3Com will make reasonable efforts to provide compatibility, except where the non-compatibility is caused by a
“bug” or defect in the third party's product.
YEAR 2000 WARRANTY
In addition to the Hardware Products Warranty and Software Products Warranty identified above, 3Com warrants that all
Heritage 3Com products sold or licensed to Customer on and after January 1, 1998 that are date sensitive will continue
performing properly with regard to such date data on and after January 1, 2000, provided that all other products used by
Customer in connection or combination with the 3Com products, including hardware, software, and firmware, accurately
exchange date data with the 3Com products, with the exception of those products identified at 3Com’s Web site,
http://www.3com.com/products/yr2000.html, as not meeting this standard. A product is considered a “Heritage 3Com product”
if it is a member of a product family which was manufactured by 3Com prior to its merger with US Robotics Corporation. This
Year 2000 limited warranty does not apply to Heritage US Robotics Corporation products. If it appears that any such product
does not perform properly with regard to such date data on and after January 1, 2000, and Customer notifies 3Com before the
later of April 1, 2000, or ninety (90) days after purchase of the product from 3Com or its authorized reseller, 3Com shall, at its
option and expense, provide a software update which would effect the proper performance of such product, repair such
product, deliver to Customer an equivalent product to replace such product, or if none of the foregoing is feasible, refund to
Customer the purchase price paid for such product.
Any software update or replaced or repaired product will carry a Year 2000 Warranty for ninety (90) days or until April 1, 2000,
whichever is later.
OBTAINING WARRANTY
SERVICE
Customer must contact 3Com’s Corporate Service Center or an Authorized 3Com Service Center within the applicable
warranty period to obtain warranty service authorization. Dated proof of purchase may be required. Products returned to
3Com’s Corporate Service Center must be pre-authorized by 3Com with a Return Material Authorization (RMA) number

Dead- or Defective-on-Arrival. In the event a product completely fails to function or exhibits a defect in materials or
workmanship within the first forty-eight (48) hours of installation but no later than thirty (30) days after the date of purchase,
and this is verified by 3Com, it will be considered dead- or defective-on-arrival (DOA) and a replacement shall be provided by
advance replacement. The replacement product will normally be shipped not later than three (3) business days after 3Com’s

specific legal rights which may vary depending on local law.
