the page where its description can be found. See the DECbrouter 90 Products
Configuration and Reference, Volume 1, DECbrouter 90 Products Configuration
and Reference, Volume 2, and DECbrouter 90 Products Configuration and
Reference, Volume 3 for more complete descriptions and examples of the
commands.

Conventions
The following conventions are used in this guide:
Convention

Meaning

system displays

Terminal sessions and information the system displays are
printed in monospace type.

boldface

Information you enter is in boldface type. Keywords are also in
boldface type.

Nonprinting characters are shown in angle brackets.

[]

Defaults are in square brackets.

COMMANDS

Commands are in uppercase letters.

italics

Command variables, worksheet values, new terms and
concepts, and titles of books and periodicals are in italics.

Ctrl/X

Indicates two keys that you must press simultaneously.

Note

Provides general information about the current topic.

Caution

Provides information to prevent damage to equipment.

If the no form of the command is not explicitly explained in the description, then
it negates the command.

EXEC System Use
•

Enter commands by typing their names at the EXEC prompt and pressing
the Return key.

•

There are two EXEC prompt levels. The user-level prompt is the server name
followed by a > as follows:
Router>
There is also a privileged-level prompt available to the system administrator
by entering a password. It is the server name followed by # as follows:
Router#

•

Use the following editing commands when typing commands at the EXEC
prompt:
Command

Function

Delete or Backspace

Erase characters

Ctrl/U

Delete line

•

As a shortcut, you can abbreviate commands to the fewest letters that make
them unique. The letters "sho" can be entered for the show command, for
example.

•

Certain EXEC commands display multiple screens with this prompt at the
bottom of the screen:
--More-Press the space bar to continue the output; type any other key to return to
the prompt.

System Help
•

Press the question mark (?) key or the h key (for help) to see a list of
available commands at either the user-level or the privileged-level EXEC
prompt.

•

Press the question mark (?) key after certain commands to get more
information about them. See the command lists for more information.

•

At any time during an active Telnet session, you can list the Telnet commands
by typing this command at the system prompt:
Ctrl ^ ?

Press the Ctrl and Shift keys and 6 keys simultaneously, let go, then enter the
question mark (?).

CONFIGURE Command
Use the privileged EXEC command configure to begin configuration of the router.
•

Begin by entering the privileged level of the EXEC. To do this, type the enable
command at the EXEC prompt:
Router> enable
The EXEC then prompts you for the privileged-level password:
Password:

•

Type the password, taking care to match uppercase and lowercase letters. For
security purposes, the password does not appear. When you enter the correct
password, the system displays the privileged-level prompt: Router#

•

To begin configuration mode, enter the configure command at the privilegedlevel prompt:
Router# configure
When you enter this command, the EXEC prompts you for the source of the
configuration subcommands.
Configuring from terminal, memory, ornetwork [terminal]?
The default is to type in commands from the terminal console. Pressing the
Return key begins this configuration method.

•

The EXEC provides you with a simple editor for entering the configuration
commands and explains the editing functions:
Enter configuration commands, one per line.
Edit with DELETE, CTRL/W, and CTRL/U; end with CTRL/Z

vii

The following table lists the edit key functions and their meanings.
Key

Meaning

Delete or Backspace

Erases one character

Ctrl/W

Erases a word

Ctrl/U

Erases a line

Ctrl/R

Redisplays a line

Return

Executes single-line commands

Ctrl/Z

Ends configuration mode and returns to the EXEC

Press Ctrl/Z to end configuration mode. Enter the disable EXEC command to
return to the user-level EXEC prompt.

Configuration Command Types
Configuration commands are categorized by these functions:

viii

•

Global configuration commands—Define system-wide parameters.

•

Interface subcommands—Define the characteristics of an interface (a serial
or Ethernet interface, for example) and must be preceded by an interface
command.

•

Line subcommands—Define the characteristics of a serial line and must be
preceded by a line command.

•

Router subcommands—Specify a routing protocol (IGRP, OSPF, and so on)
and must be preceded by a router command.
Observe the following guidelines when you enter configuration commands:

•

As with EXEC commands, you can type configuration subcommands in
uppercase letters, lowercase letters, or both. You also can shorten all
commands and other keywords to the fewest number of characters that
uniquely identify the word.

•

To add a comment, begin the line with an exclamation point (!). Comments do
not affect command processing.

•

If the router encounters a problem, it displays an error message on the
console terminal.
