According to the SFF-8472 Management Interface for SFP+ specification transceiver EEPROM (A2h) byte 00 - 39 used to access measurements of transceiver temperature, internally measured supply voltage, TX bias current, TX output power, received optical power.

Switch supports transceiver-monitor feature monitoring these DDM information, and switch also supports setting warning and alarm threshold value of monitoring transceiver DDM information.

Show transceiver information

Command: show interfaces transceiver [interface]

This command displays identifying information for the specified transceiver, including connector type and vendor-related parameters, as well as the temperature, voltage, bias current, transmit power, and receive power.

To enable transceiver’s operational values monitoring.

Command: [no] transceiver-monitor

This command sends a trap when any of the transceiver’s operational values fall outside of specified thresholds. Use the no form to disable trap messages.

Console(config)#int ethernet 1/27
Console(config-if)#transceiver-monitor

To modify transceiver-monitor threshold value

4.1 To disabled uses default threshold settings obtained from the transceiver.

Command:[no] transceiver-threshold-auto

This command uses default threshold settings obtained from the transceiver to determine when an alarm or warning message should be sent. Use the no form to disable this feature.

Console(config-if)#no transceiver-threshold-auto

4.2 To modify transceiver-monitor threshold value.

Command: transceiver-threshold [threshold item] [threshold values]

This command sets thresholds for the transceiver power level of the received signal which can be used to trigger an alarm or warning message. Use the no form to restore the default settings.

Console(config-if)#transceiver-threshold ?
  current      Sets current threshold
  rx-power     Sets threshold rx-power
