Configuring Transmit Shutdown on Trunk Optics Controller
To perform transmit shutdown, enter the following commands:
RP/0/RP0/CPU0:ios#configure
RP/0/RP0/CPU0:ios(config)#controller Optics R/S/I/P
RP/0/RP0/CPU0:ios(config-Optics)#transmit-shutdown
RP/0/RP0/CPU0:ios(config-Optics)#exit
RP/0/RP0/CPU0:ios(config)#exit
The following is a sample to perform transmit shutdown on the trunk port:
RP/0/RP0/CPU0:ios#configure
RP/0/RP0/CPU0:ios(config)#controller Optics 0/1/0/12
RP/0/RP0/CPU0:ios(config-Optics)#transmit-shutown
RP/0/RP0/CPU0:ios(config-Optics)#exit
RP/0/RP0/CPU0:ios(config)#exit
