Nortel VPN Router Configuration — Basic Features
Preface
This guide introduces the Nortel VPN Router. It also provides overview and basic
configuration information to help you initially set up your Nortel VPN Router.
Before you begin
This guide is for network managers who are responsible for setting up and
configuring the Nortel VPN Router. This guide assumes that you have experience
with windowing systems or graphical user interfaces (GUIs) and familiarity with
network management.
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>, you enter
ping 192.32.10.12
bold Courier text Indicates command names and options and text that
you need to enter.
Example: Use the show health command.
Example: Enter terminal paging {off | on}.
16 Preface
NN46110-500
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 ldap-server
source {external | internal}, you must enter
either ldap-server source external or
ldap-server source internal, but not both.
brackets ([ ]) Indicate optional elements in syntax descriptions. Do
not type the brackets when entering the command.
Example: If the command syntax is
show ntp [associations], you can enter
either show ntp or show ntp associations.
Example: If the command syntax is default rsvp
[token-bucket {depth | rate}], you can enter
default rsvp, default rsvp token-bucket
depth, or default rsvp token-bucket rate.
ellipsis points (. . . ) Indicate that you repeat the last element of the
command as needed.
Example: If the command syntax is
more diskn:<directory>/...<file_name>,
you enter more and the fully qualified name of the file.
italic text Indicates 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
ping <ip_address>, ip_address is one variable
and you substitute one value for it.
plain Courier
text Indicates system output, for example, prompts and
system messages.
Example: File not found.
