| 1.4.8 |  | Identifying individual ports |

A description added to an interface or port will help identify specific information about that interface. For example, information could include what access or distribution-layer device the interface services. This command is very useful in an environment where a switch has numerous connections and the administrator needs to check a link to a specific location. This description is meant solely as a comment to help identify how the interface is being used or where it is connected. This description could include the floor number or the office number or name. The description will appear in the configuration information output.

To add a unique comment to an interface on a Cisco IOS-based switch, enter the following command in interface configuration mode:

> Switch(config-if)#description description string

The string may be up to 80 characters.

To clear a description, enter the no description command on the interface in interface configuration mode.
