| 3.2.2 |  | Interface descriptions |

| An interface description should be used to identify important information such as a distant router, a circuit number, or a specific network segment. A description of an interface can help a network user remember specific information about the interface, such as what network the interface services. The description is meant solely as a comment about the interface. Although the description appears in the configuration files that exist in router memory, a description does not affect the operation of the router. Descriptions are created by following a standard format that applies to each interface. The description may include the purpose and location of the interface, other devices or locations connected to the interface, and circuit identifiers. Descriptions allow support personnel to better understand the scope of problems related to an interface and allow for faster resolution of problems.
