16.3 Examples of DDM
Example1:
Ethernet 21 and Ethernet 23 are inserted the fiber module with DDM, Ethernet 24 is inserted
the fiber module without DDM, Ethernet 22 does not insert any fiber module, show the DDM
information of the fiber module.
a、Show the information of all interfaces which can read the real-time parameters normally,(No
fiber module is inserted or the fiber module is not supported, the information will not be shown),
for example:
Switch#show transceiver
Interface Temp（℃） Voltage（V） Bias（mA） RX Power（dBM）
（dBM）
1/21
33
1/23

b、Show the information of the specified interface. (N/A means no fiber module is inserted or
does not support the fiber module), for example:
Switch#show transceiver interface ethernet 1/21-22;23
Interface Temp （℃） Voltage （V） Bias （mA） RX Power （ dBM）
1/21
33
1/22
N/A
1/23

c、Show the detailed information, including base information, parameter value of the real-time
monitoring, warning, alarm, abnormity state and threshold information, for example:
Switch#show transceiver interface ethernet 1/21-22;24 detail
