User-Defined CLI Persistent Variables

You can define CLI variables that persist across CLI sessions and switch reloads using the cli var name
command in configuration mode. These CLI persistent variables are configured in configuration mode
and are saved in the running configuration file.
As of MDS NX-OS Release 4.1(1a), CLI session variables are not supported.
Note
The following example shows how to create a user-defined CLI persistent variable:
switch# config t
switch(config)# cli var name mgmtport mgmt 0
switch(config)# exit
switch#
You can reference a variable using the syntax $(variable).
The following example shows how to reference a user-defined CLI persistent variable:
switch# show interface $(mgmtport)
mgmt0 is up
Use the show cli variables command to display user-defined CLI persistent variables.
The following example displays user-defined CLI persistent variables:
switch# show cli variables

variables.

You cannot reference a variable through another variable using nested references.
You can define persistent variables that are available across switch reloads.
You can reference only one predefined system variable, the TIMESTAMP variable.
