Adding A Description For An Interface; Configuring Layer 3 Svis - Cisco Catalyst 2975 Software Configuration Manual

Chapter 12 Configuring Interface Characteristics
To disable policing of the real-time power consumption, use the no power inline police interface
configuration command. To disable error recovery for PoE error-disabled cause, use the no errdisable
recovery cause inline-power global configuration command.
For information about the output from the show power inline police privileged EXEC command, see
the command reference for this release.

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 interfaces.
Beginning in privileged EXEC mode, follow these steps to add a description for an interface:
Command
Step 1
configure terminal
Step 2 interface interface-id
Step 3 description string
Step 4 end
Step 5
show interfaces interface-id description
or
show running-config
Step 6 copy running-config startup-config
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
Switch# show interfaces gigabitethernet1/0/2 description
Interface Status
Gi1/0/2

Configuring Layer 3 SVIs

You should configure SVIs for any VLANs for which you want to route traffic. SVIs are created when
you enter a VLAN ID following the interface vlan global configuration command. To delete an SVI,
use the no interface vlan global configuration command. You cannot delete VLAN 1.
