Adding a Description for an Interface

You can add a description about an interface to help you remember its function. The description appears in the output of these privileged EXEC commands: show configuration, show running-config,and show interfaces.

Beginning in privileged EXEC mode, follow these steps to add a description for an interface:

	Command	Purpose
Step 1
	configure terminal	Enter global configuration mode.
Step 2
	interface interface-id	Specify the interface for which you are adding a description, and enter
		interface configuration mode.
Step 3
	description string	Add a description (up to 240 characters) for an interface.
Step 4
	end	Return to privileged EXEC mode.
Step 5
	show interfaces interface-iddescription	Verify your entry.
	or
	show running-config
Step 6
	copy running-config startup-config	(Optional) Save your entries in the configuration file.

Use the no description interface configuration command to delete the description.

This example shows how to add a description on a port and how to verify the description:

Switch# config terminal

Enter configuration commands, one per line. End with CNTL/Z.

Switch(config)# interface gigabitethernet1/0/2

Switch(config-if)#description Connects to Marketing

Switch(config-if)# end
