Impact on the System

Services will not be affected.

Possible Causes

  • Cause 1: A new interface neighbor was discovered.

  • Cause 2: An interface neighbor was deleted.

  • Cause 3: An interface neighbor was aged because the aging period expired.

Procedure

  • Cause 1: A new interface neighbor was discovered.
    1. Run the display lldp neighbor command to check whether LLDP is enabled on the new interface neighbor.

      • If yes, this trap message is informational only and no action is required.
      • If not, go to 2.

    2. Collect log information and configuration information, and then contact technical support personnel.
  • Cause 2: An interface neighbor was deleted.
    1. Run the display lldp neighbor command to check whether LLDP is disabled on the interface neighbor.

      • If yes, run the lldp enable command in the system view of the neighboring device to enable LLDP.
      • If not, go to 2.

    2. Run the display interface brief command to check whether a link fault has occurred between the local and neighboring devices.

      • If yes, rectify the link fault.
      • If not, go to 3.

    3. Collect log information and configuration information, and then contact technical support personnel.
  • Cause 3: An interface neighbor was aged because the aging period expired.
    1. Run the display lldp statistic command to check whether neighboring node information saved on the local device has timed out.

      • If yes, this trap message is informational only and no action is required.
      • If not, go to 2.

    2. Check whether the interface connecting the local and neighboring devices has been shut down.

      • If yes, run the undo shutdown command on the interface to configure it to go Up.
      • If not, go to 3.

    3. Run the display health command to check CPU usage to determine whether the link between the local and neighboring devices is congested.

      • If yes, stop the transmission of irrelevant traffic to remove the congestion.
      • If not, go to 4.

    4. Collect log information and configuration information, and then contact technical support personnel.
