1.Run the display transceiver slot slot-id verbose command in the system view to check whether the receive power Rx Power of the optical module is within the allowed range. If so, collect alarms, logs, and configurations, and contact technical support personnel.
2.If no alarm on low receive power is generated and the peer interface is Up, go to step 5.
3.If the peer interface is Down and an alarm on that is generated, rectify the peer interface.
4.Check whether the optical fiber is faulty. If so, replace the optical fiber.
5.Perform an external loopback test on the interface. If the interface is in Up state, perform loopback tests on the nodes along the transmission path to locate the failure point or link.
6.Replace the local optical module.
7.If the fault persists after the optical module is replaced, collect alarms, logs, and configurations, and contact technical support personnel.

Hello,
Run the display transceiver interface interface-type interface-number verbose command to view the optical module parameter settings.

All the parameters of each optical module must be within the acceptable range, especially the transmit and receive power.

A switch will send the following traps for abnormal power:
  • Low optical power

    ENTITYTRAP_1.3.6.1.4.1.2011.5.25.219.2.4.5 hwOpticalInvalid 136194

    ENTITYTRAP/3/OPTICALINVALID: OID [oid] Optical Module is invalid.(Index=[INTEGER], EntityPhysicalIndex=[INTEGER], PhysicalName="[OCTET]", EntityTrapFaultID=[INTEGER])

  • High optical power

    ENTITYTRAP_1.3.6.1.4.1.2011.5.25.219.2.4.5 hwOpticalInvalid 136195

    ENTITYTRAP/3/OPTICALINVALID: OID [oid] Optical Module is invalid.(Index=[INTEGER], EntityPhysicalIndex=[INTEGER], PhysicalName="[OCTET]", EntityTrapFaultID=[INTEGER])

The following measures can be taken if the optical power is abnormal:

  • If the transmit power is too high or low, replace the optical module.
  • If the receive power is too high or low:
    • Replace the optical module or fiber.
    • Check whether the optical module and fiber meet requirements.
    • Use an optical power meter to measure the attenuation of each part of links and recover the problematic link.
    • Check whether the transmit and receive fibers are correctly connected. Generally, two optical modules are connected by two fibers. The TX and RX ends of one module are respectively connected to the RX and TX ends of another module.

from your diagnostic information, the current receive power(-15.64) is lower than the low warning threshold(-14.40).
