Interface alias names

An interface alias is a textual description of a logical unit on a physical interface. An alias enables you to give a single meaningful and easily identifiable name to an interface. Interface aliasing is supported only at the unit level.

The alias name is displayed instead of the interface name in the output of all show, show interfaces, and other operational mode commands. Configuring an alias for a logical unit of an interface has no effect on how the interface operates on the device.
