LACP/3/OPTICAL_FIBER_MISCONNECT: The member of the LACP mode Eth-Trunk interface received an abnormal LACPDU, which may be caused by optical fiber misconnection. (TrunkName=[STRING], PortName=[STRING], LocalParam=[STRING], PDUParam=[STRING])


The member of an Eth-Trunk interface in static LACP mode received an abnormal LACPDU, which may be caused by the optical fiber misconnection.


Parameter Name Parameter Meaning
TrunkName Name of an Eth-Trunk interface in static LACP mode
PortName Name of the member interface of the Eth-Trunk interface in static LACP mode
LocalParam Local parameters
PDUParam Local parameters received using LACPDUs

Possible Causes

The optical fiber connection was incorrect, or packets were invalid.


During an LACP negotiation between a Huawei device and a non-Huawei device, if the non-Huawei device implementation does not completely comply with the LACP protocol standard, the log may be reported on the Huawei device.


  1. Check whether the members of the Eth-Trunk interface in static LACP mode have optical fibers incorrectly connected based on LocalParam and PDUParam in the log.

    • If optical fibers were connected incorrectly, go to Step 2.
    • If optical fibers were connected correctly, go to Step 3.

  2. Connect the optical fibers correctly.
  3. Collect log information and configuration information, and then contact technical support personnel.
