Configuring an Interface Description

Problem

You want to include a description of an interface in the configuration.

Solution

Use the following command to configure a description of the interface:

	[edit interfaces fe-0/0/0]
	aviva@router1# set interfaces fe-0/0/0 description "to router2 fe-0/0/0"

 

Discussion

It's often convenient to include a short description of the interface to make a note of any administrative information that is useful to you or your staff, such as the remote interface. This recipe sets a description of the interface that describes the remote router and interface that is at the other end of this link.

The configured interface description script shows up in the show interfaces command output:

	aviva@router1> show interfaces fe-0/0/0
	Physical interface: fe-0/0/0, Enabled, Physical link is Up
	 Interface index: 128, SNMP ifIndex: 79
	 Description: to router2 fe-0/0/0
	 Link-level type: Ethernet, MTU: 1514, Speed: 100mbps, Loopback: Disabled,
	 Source filtering: Disabled, Flow control: Enabled
	 Device flags : Present Running
	 Interface flags: SNMP-Traps 16384
	 …

You can use the show interfaces descriptions command to list the descriptions for all interfaces:

	aviva@router1> show interfaces descriptions
	Interface Admin Link Description
	fe-0/0/0 up up to router2 fe-0/0/0
	fe-0/0/1 up up to router2 fe-0/0/1
	fe-0/0/2 up up to router2 fe-0/0/2
