Ethernet 1/22 transceiver threshold-violation information: 
Transceiver  monitor  is  disabled.  Monitor  interval  is  set  to  30 
minutes. 
The last threshold-violation doesn’t exist. 
Step2: Enable the transceiver monitoring of ethernet 21. 
Switch(config)#interface ethernet 1/21 
Switch(config-if-ethernet1/21)#transceiver-monitoring enable 
Step3:  Show  the  transceiver  monitoring  of  the  fiber  module.  In  the  following  configuration, 
ethernet  21  enabled  the  transceiver  monitoring,  the  last  threshold-violation  time  is  Jun  02 
11:00:50 2012, the detailed DDM information exceeding the threshold is also shown.
