Detail diagnostic and threshold information: N/A
Example2:
Ethernet 1/21 is inserted the fiber module with DDM. Configure the threshold of the fiber
module after showing the DDM information.
Step1: Show the detailed DDM information.
Switch#show transceiver interface ethernet 1/21 detail
Ethernet 1/21 transceiver detail information:
Base information:
……
Brief alarm information:
RX loss of signal
Voltage high
RX power low
Detail diagnostic and threshold information:
Diagnostic Threshold
Realtime Value High Alarm Low Alarm High Warn Low Warn
-------------- ----------- ----------- ------------ ---------
Temperature (°C) 33 70 0 70 0
Voltage (V) 7.31(A+) 5.00 0.00 5.00 0.00
Bias current (mA) 6.11(W+) 10.30 0.00 5.00 0.00
RX Power (dBM) -30.54(A-) 9.00 -25.00 9.00 -25.00
TX Power (dBM) -13.01 9.00 -25.00 9.00 -25.00
Step2: Configure the tx-power threshold of the fiber module, the low-warning threshold is -12,
the low-alarm threshold is -10.00.
Switch#config
Switch(config)#interface ethernet 1/21
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.
