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.
