User-Defined Persistent CLI Variables

You can define CLI session variables to persist only for the duration of your CLI session using the cli
var name command in EXEC mode. CLI session 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). The following example shows how to
reference a user-defined CLI session variable:
switch# show interface $(testinterface)
fc2/1 is up
Hardware is Fibre Channel, SFP is short wave laser w/o OFC (SN)

Common Configuration Submodes (continued)
From Configuration Mode, Enter:
zone name string vsan vsan-id
zoneset name name vsan vsan-id
Entered directly on the command line.
Passed to the child script initiated using the run-script command.
The variables defined in the parent shell are available for use in the child run-script command
process (see the "Executing Commands Specified in a Script" section on page
Passed as command line arguments to the run-script command (see the
Specified in a Script" section on page
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, which is the TIMESTAMP variable.
