Interface Configuration Commands
shutdown
To disable an interface, use the shutdown command. To restart a disabled interface, use the no form of
this command.
shutdown
no shutdown
Syntax Description This command has no other arguments or keywords.
Defaults Disabled
Command Modes Interface configuration
Usage Guidelines This command disables all functions on the specified interface.
This command also marks the interface as unavailable. To check whether an interface is disabled, use
the show interfaces command. An interface that has been shut down is shown as administratively down
in the show interfaces output.
On transparent and wave interfaces, use the shutdown command to turn off the transmit lasers. To turn
the transmit lasers on, use the no shutdown command.
A shutdown command issued on a wave, waveethernetphy, or tengigethernetphy interface does not
affect administrative status of the corresponding wavepatch interfaces. To administratively shut down the
wavepatch interfaces, issue shutdown commands directly.
To use splitter line cards for line card protection, you must shut down all the wavepatch interfaces.
(See the “Example s” section.)
Examples The following example shows how to shut down a wave interface, which also turns off the laser that
transmits to the trunk fiber.
Switch# configure terminal
Switch(config)# interface wave 3/0
Switch(config-if)# shutdown
The following example shows how to reenable a transparent interface and turn on the laser transmitting
