CLI Guide

Version Description
7.5.1.0 Introduced on the C-Series.
Usage
Information
The shutdown command marks a physical interface as unavailable for traffic. To discover if an interface
is disabled, use the show ip interface brief command. Disabled interfaces are listed as down.
Disabling a VLAN or a port channel causes different behavior. When a VLAN is disabled, the Layer 3
functions within that VLAN are disabled. Layer 2 traffic continues to flow. Entering the shutdown
command on a port channel disables all traffic on the port channel and the individual interfaces within the
port channel. To enable a port channel, enter no shutdown on the port channel interface and at least
one interface within that port channel.
The shutdown and description commands are the only commands that you can configure on an
interface that is a member of a port channel.
