) or Site Manager to configure

Before You Begin

Before using this guide, you must complete the following procedures. For a new router:

• Install the router (see the installation guide that came with your router).

• Connect the router to the network and create a pilot configuration file (see Quick-Starting Routers).

Make sure that you are running the latest version of Bay Networks BayRS Site Manager software. For information about upgrading BayRS and Site Manager, see the upgrading guide for your version of BayRS.

Text Conventions

This guide uses the following text conventions:

angle brackets (< >) Indicate that you choose the text to enter based on the

description inside the brackets. Do not type the brackets when entering the command. Example: If the command syntax is:

ping

<ip_address>

ping 192.32.10.12

, you enter:

bold text

Indicates text that you need to enter and command names and options. Example: Enter

show ip {alerts | routes

Example: Use the

dinfo

command.

}

braces ({}) Indicate required elements in syntax descriptions

where there is more than one option. You must choose only one of the options. Do not type the braces when entering the command. Example: If the command syntax is:

show ip {alerts | routes show ip alerts or show ip routes

, you must enter either:

}

brackets ([ ]) Indicate optional elements in syntax descriptions. Do

not type the brackets when entering the command. Example: If the command syntax is:

show ip interfaces [-alerts show ip interfaces

, you can enter either:

]

show ip interfaces -alerts

xxiv

117374-C Rev 00

Preface

ellipsis points (. . . ) Indicate that you repeat the last element of the

command as needed. Example: If the command syntax is:

ethernet/2/1 [< ethernet/2/1 and as many parameter-value pairs as

parameter> <value>

] . . ., you enter

needed.

italic text Indicates file and directory names, new terms, book

titles, and variables in command syntax descriptions. Where a variable is two or more words, the words are connected by an underscore. Example: If the command syntax is:

show at <

valid_route

valid_route>

is one variable and you substitute one value

for it.

screen text Indicates system output, for example, prompts and

system messages. Example:

Set Bay Networks Trap Monitor Filters

separator ( > ) Shows menu paths.

Example: Protocols > I P ide nti fies the IP option on the Protocols menu.

vertical line (

) Separates choices for command keywords and

arguments. Enter only one of the choices. Do not type the vertical line when entering the command. Example: If the command syntax is:

117374-C Rev 00

show ip {alerts | routes}, you enter either: show ip alerts or show ip routes, but not both.
