LLDP/4/LLDP_INTERFACE_REM_CHANGE

Message

LLDP/4/LLDP_INTERFACE_REM_CHANGE: Neighbor information of the interface was changed. (Interface=[interfaceName], Action=[action], Added=[lldpRemInserts], Deleted=[lldpRemDeletes], RemoteInterfaceName=[remInterfaceName], RemoteDeviceManageAddress=[remManageAddress])

Description

The neighbor information about an interface was changed.

Parameters

Parameter Name Parameter Meaning

interfaceName

Interface name

action

Whether interface neighbors are added or deleted

lldpRemInserts

Number of added neighbors

lldpRemDeletes

Number of deleted neighbors

remInterfaceName

Remote interface name

remManageAddress

Peer device management-address

Possible Causes

Cause 1: A new neighbor was discovered.

Cause 2: The neighbor relationship was deleted.

Cause 3: A neighbor was aged because the aging period expired.

Procedure

Cause 1: A new neighbor was discovered.

1. Run the display lldp neighbor command, check whether LLDP is enabled for the new 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: The neighbor relationship was deleted.

1. Run the display lldp neighbor command, check whether LLDP is disabled for the new neighbor.

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

2. Run the display interface brief command, check whether a link fault occurs between the local device and the neighbor.

  • 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: A neighbor was aged because the aging period expired.

1. Run the display lldp statistic command, check whether neighboring node information saved on the local device times 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 device and the neighbor 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, check CPU resource exhaustion to determine whether the link between the local device and the neighbor 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.
