4000 Router Series Interface Command Reference

Parameters

interface-number: Specifies an asynchronous interface by its number.

brief: Displays brief interface information. If you do not specify this keyword, the command displays

detailed interface information.

down: Displays information about interfaces in physically DOWN state and the causes. If you do not

specify this keyword, the command displays information about interfaces in all states.

description: Displays complete interface descriptions. If you do not specify this keyword, the command

displays only the first 27 characters of interface descriptions.

Usage guidelines

If you do not specify the async keyword, this command displays information about all interfaces on the

device.

If you specify the async keyword without the interface-number argument, this command displays

information about all existing asynchronous interfaces.
