Lab A.11: Setting Interface Descriptions
S
etting descriptions on an interface is helpful to the administrator
and, like the hostname, only locally significant. This is a helpful command
because it can be used to keep track of circuit numbers, among other things.
1.
Set the description of the interface Ethernet 0 to Sales LAN and
the serial 0 interface to WAN to Miami with a circuit number of
6fdda4321.
Todd(config)#int e0
Todd(config-if)#description Sales Lan
Todd(config-if)#int s0
Todd(config-if)#description Wan to Miami
circuit:6fdda4321
2.
You can view the description of an interface either with the show
running-config
or the show interface command.
Todd#sh run
[output cut]
interface Ethernet0
