Possible Causes
  • Cause 1: A neighbor is found.
  • Cause 2: A neighbor is deleted.
  • Cause 3: A neighbor is discarded because of insufficient space.
  • Cause 4: A neighbor is aged.
Procedure
  • Cause 1: A neighbor is found.
    1. Check whether LLDP is enabled on the neighbor.
      • If LLDP is enabled, this log message is informational only, and no action is required.
      • LLDP is not enabled, go to Step 2.
    2. Collect information about configurations, trap messages, and log messages, and then contact technical support personnel.
  • Cause 2: A neighbor is deleted.
    1. Check whether LLDP is disabled on the neighbor.
      • If LLDP is disabled, run the lldp enable (system view) command on the neighbor.
      • If LLDP is not disabled, go to Step 2.
    2. Check whether the link between the neighbor and local device is faulty.
      • If the link is faulty, rectify the fault.
      • If the link is normal, go to Step 3.
    3. Collect information about configurations, trap messages, and log messages, and then contact technical support personnel.
  • Cause 3: A neighbor is discarded because of insufficient space.
    1. Check whether the number of neighbors stored on the local device has reached the maximum limit.
      • If the number of neighbors has reached the maximum limit, this log message is informational only, and no action is required.
      • If the number of neighbors has not reached the maximum limit, go to Step 2.
    2. Collect information about configurations, trap messages, and log messages, and then contact technical support personnel.
  • Cause 4: A neighbor is aged.
    1. Check whether neighbor information stored on the local device has timed out.
      • If neighbor information has timed out, this log message is informational only, and no action is required.
      • If neighbor information has not timed out, go to Step 2.
    2. Check whether the interfaces used to connect the neighbor to the 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 neighbor and local device is congested.
      • If the link is congested, stop unnecessary traffic to alleviate the 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.

Possible Causes
  • Cause 1: An MDN neighbor is found.

  • Cause 4: An MDN neighbor is aged.
Procedure
  • Cause 1: An 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: An MDN neighbor is deleted.
    1. Check whether an MDN neighbor has been deleted.
      • If an 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: An MDN neighbor is discarded because of insufficient space.
