Setting the Switch's Terminal Width

To set the terminal screen width for the current session, use the terminal width command in EXEC
mode. This command is specific to only the console port. Telnet and SSH sessions set the width
automatically.
The syntax for this command is terminal width columns
switch# terminal width 86
Sets the screen length for the current session to 86 columns for the current terminal session. The default
is 80 columns.

Displaying Terminal Settings

The show terminal command displays the terminal settings for the current session:
switch# show terminal
TTY: Type: "vt100"
Length: 24 lines, Width: 80 columns
Session Timeout: 525600 minutes

command in EXEC mode. These CLI variables are useful for scripts that you execute periodically.
The following example shows how to create a user-defined CLI session variable.
switch# cli var name testinterface fc 1/1
You can reference a variable using the syntax $(variable).
