Switch(config-if-ethernet1/21)#transceiver threshold tx-power low-
warning -12
Switch(config-if-ethernet1/21)#transceiver threshold tx-power low-
alarm -10.00
Step3: Show the detailed DDM information of the fiber module. The alarm uses the threshold
configured by the user, the threshold configured by the manufacturer is labeled with the
bracket. There is the alarm with ‘A-’ due to -13.01 is less than -12.00.

Example3:
Ethernet 21 is inserted the fiber module with DDM. Enable the transceiver monitoring of the
port after showing the transceiver monitoring of the fiber module.
Step1: Show the transceiver monitoring of the fiber module. Both ethernet 21 and ethernet 22
do not enable the transceiver monitoring, its interval is set to 30 minutes.
Switch(config)#show transceiver threshold-violation interface
ethernet 1/21-22
Ethernet 1/21 transceiver threshold-violation information:
Transceiver monitor is disabled. Monitor interval is set to 30
minutes.
The last threshold-violation doesn’t exist.
