these keys may be defined to perform other operations. If so, the definition of the terminal software will

Configuring Command Aliases
You can replace the first keyword of a command supported by the device with your preferred keyword
by configuring the command alias function. For example, if you configure
show
as the replacement of
the
display
keyword for each
display
command, you can input the command alias
show xx
to execute
the
display xx
command.
Note the following when you configure command aliases:

When you input a command alias, the system displays and saves the command in its original
format instead of its alias. That is, you can define and use a command alias but the command is not
saved and restored in its alias.

When you define a command alias, the
cmdkey

alias
arguments must be in complete form.

If you press

after you input the keyword of an alias, the original format of the keyword will be
displayed.

You can replace only the first keyword of a non-undo command instead of the complete command;

undo
commands.

Configuring User Privilege Levels and Command Levels
Introduction
To restrict the different users’ access to the device, the system manages the users by their privilege
levels. User privilege levels correspond to command levels. After users at different privilege levels log in,
