Configure receive power threshold

Enter the rx-high-thresholdrx-highrx-low-thresholdrx-lowR/S/I/P command to configure the high and low receive power threshold.

Example:

This sample configures the high receive power threshold on the controller optics.


RP/0/RP0/CPU0:ios#configure
RP/0/RP0/CPU0:ios(config)#controller optics 0/0/0/7
RP/0/RP0/CPU0:ios(config-Optics)#rx-high-threshold -20
RP/0/RP0/CPU0:ios(config-Optics)#rx-low-threshold -30
RP/0/RP0/CPU0:ios(config-Optics)#commit

This sample shows the high receive power threshold configured on the controller optics.
