LLDP/4/LLDP_MDN_REMTABLECHANGE

LLDP/4/LLDP_MDN_REMTABLECHANGE

Message

LLDP/4/LLDP_MDN_REMTABLECHANGE: MDN Neighbor information was changed.

Description

MDN neighbor information is changed.

Parameters

Parameter Name Parameter Meaning

None

None

Possible Causes

  • Cause 1: A MDN neighbor is found.

  • Cause 2: A MDN neighbor is deleted.

  • Cause 3: A MDN neighbor is discarded because of insufficient space.

  • Cause 4: A MDN neighbor is aged.

Procedure

  • Cause 1: A MDN neighbor is found.
    1. Check whether a new MDN neighbor is found.

      • If a new MDN neighbor is found, this log message is informational only, and no action is required.
      • If no new MDN neighbor is found, go to Step 2.

    2. Collect information about configurations, trap messages, and log messages, and contact technical support personnel.
  • Cause 2: A MDN neighbor is deleted.
    1. Check whether a MDN neighbor has been deleted.

      • If a MDN neighbor has been deleted, this log message is informational only, and no action is required.
      • If no MDN neighbor has been deleted, go to Step 2.

    2. Check whether the link between the local device and its MDN neighbor is faulty.

      • If the link is fault, rectify the fault.
      • If the link is normal, go to Step 3.

    3. Collect information about configurations, trap messages, and log messages, and contact technical support personnel.
  • Cause 3: A MDN neighbor is discarded because of insufficient space.
    1. Check whether the number of MDN neighbors stored on the local device has reached the maximum limit.

      • If the number of MDN neighbors has reached the maximum limit, this log message is informational only, and no action is required.
      • If the number of MDN neighbors has not reached the maximum limit, go to Step 2.

    2. Collect information about configurations, trap messages, and log messages, and contact technical support personnel.
  • Cause 4: A MDN neighbor is aged.
    1. Check whether the MDN neighbor information stored on the local device has timed out.

      • If the MDN neighbor information has timed out, this log message is informational only, and no action is required.
      • If the MDN neighbor information has not timed out, go to Step 2.

    2. Check whether the interfaces used to connect the MDN neighbor and local device are shut down.

      • If an interface is shut down, run the undo shutdown command on this interface.
      • If no interface is shut down, go to Step 3.

    3. Check the usage of CPU resources to determine whether the link between the MDN neighbor and local device is congested.

      • If the link is congested, stop unnecessary traffic to alleviate link congestion.
      • If the link is not congested, go to Step 4.

    4. Collect information about configurations, trap messages, and log messages, and then contact technical support personnel.
