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.
