How to Use the Command-line Interface

Avaya M770 ATM Switch User’s Guide

How the Command-line Interface Works

The command-line interface provides a set of commands that you can use to 
configure the M770 ATM Switch. The commands are arranged in a hierarchy such 
that related commands are grouped together in a single functional group. A 
functional group can also contain one or more functional groups, and so forth. 
When you login to the command-line interface, you will be placed at the root of the 
hierarchy. To perform an operation using a command, you will need to specify the 
full hierarchical path followed by the command. For example:

This command shows routes in the routing table and is contained in the 

route

 

functional group. Alternatively, you can descend the hierarchy by typing:

This will cause the prompt to change, displaying the position in the hierarchy:

You can now perform the command simply by typing 

show

, as follows:

The advantage of descending the hierarchy is that you can perform multiple related 
commands without having to type them out in full (that is, specifying their full 
hierarchical path).

You do not need to enter all the letters of a command: you need only enter 

sufficient letters to uniquely identify it from other commands in the directory. For 
example, instead of typing 

route show

 you could just enter 

r s 

in the 

command-line interface. You can also use the TAB key to complete the full 
command.

Table 3.1 lists the commands that are used to navigate the hierarchy.
