How Do I Query the Optical Power of an Interface?

How Do I Query the Optical Power of an Interface?

You can run the display interface [ interface-type interface-number | slot slot-id ] transceiver verbose command to check the optical power of interfaces.

<HUAWEI> display interface 10ge 1/0/1 transceiver verbose

 10GE1/0/1 transceiver information:
-------------------------------------------------------------------
......
-------------------------------------------------------------------
 Diagnostic information:
   Temperature (Celsius)                 :33.59
   Voltage (V)                           :3.37
   Bias Current (mA)                     :6.30
   Bias High Threshold (mA)              :10.50
   Bias Low Threshold (mA)               :2.50
   Current RX Power (dBm)                :0.50       //Indicate the current receive power of the optical module.
   Default RX Power High Threshold (dBm) :3.01       //Indicate the receive power upper threshold of the optical module.
   Default RX Power Low Threshold (dBm)  :-15.02     //Indicate the receive power lower threshold of the optical module.
   Current TX Power (dBm)                :-2.38      //Indicate the current transmit power of the optical module.
   Default TX Power High Threshold (dBm) :3.01       //Indicate the transmit power upper threshold of the optical module.
   Default TX Power Low Threshold (dBm)  :-9.00      //Indicate the transmit power lower threshold of the optical module.
-------------------------------------------------------------------

When the receive or transmit power of an optical module exceeds the upper threshold or falls below the lower threshold, the optical module may fail to work properly.
