User-Defined Persistent Cli Variables - Cisco AP775A - Nexus Converged Network Switch 5010 Configuration Manual

Using CLI Variables
• Passed as command line arguments to the run-script command.
CLI variables have the following characteristics:
• 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.

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)
Use the show cli variables command to display user-defined CLI session variables. The following example
displays user-defined CLI session variables:
switch# show cli variables
VSH Variable List
-----------------
TIMESTAMP="2005-10-24-21.29.33"
testinterface="fc 1/1"
Use the cli no var name command to remove user-defined CLI session variables. The following example
removes a user-defined CLI session variable:
switch# cli no var name testinterface
OL-16597-01
The variables defined in the parent shell are available for use in the child run-script command process.
