Reference Guide
Disabling a VLAN or a port channel causes dierent behavior. When a VLAN is disabled, the Layer 3
functions within that VLAN are disabled. Layer 2 trac continues to ow. Entering the shutdown
command on a port channel disables all trac on the port channel and the individual interfaces within the
port channel. To enable a port channel, you must 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 congure on an
interface that is a member of a port channel.
