History
Version 8.3.16.1
Introduced on the MXL 10/40GbE Switch IO Module.
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 you disable a
VLAN, 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.
