Usage Guidelines Use this command to explicitly shut down the laser. The interface shutdown command disables data
traffic; however the control traffic carried over in-band message channel continues to flow. Use this
command to turn off the laser and stop all traffic.
Note The interface shutdown command must precede the laser shutdown command. To bring the interface
administratively up, the no laser shutdown must precede the no shutdown command.
Note If you turn off the laser on an interface and save the configuration to the startup configuration, the
interface comes up with the laser turned off when the system boots.
Note A 10-Gbps laser on a waveethernetphy interface must warm up for 2 m inute s b ef ore c arr ying t raffic.
