ISIS/6/ISIS_RCV_OWN_PURGED_LSP

Message

ISIS/6/ISIS_RCV_OWN_PURGED_LSP: ISIS [ProcessId] received an own purged LSP. (Level=[Level], PduLspId=[PduLspId], Interface=[Interface], NbrSystem=[NbrSystem], SrcSystem=[SrcSystem], SrcDynName=[SrcDynName], SrcNbrSystem=[SrcNbrSystem])

Description

The IS-IS system received an LSP with the remaining time being 0 generated by the local device and sent by another system.

Parameters

Parameter Name	Parameter Meaning
ProcessId	Indicates the IS-IS process ID.
Level	Indicates the IS-IS level.
PduLspId	Indicates the ID of the purged LSP.
Interface	Indicates the interface that receives the purged LSP.
NbrSystem	Indicates the system ID of a neighbor.
SrcSystem	Indicates the system ID of the device that sends the purged LSP.
SrcDynName	Indicates the dynamic hostname of the device that sends the purged LSP.
SrcNbrSystem	Indicates the neighbor system ID of the device that sends the purged LSP.

Possible Causes

Cause 1: The local device does not update its LSPs in time. As a result, the purge packets generated after the locally generated LSPs age out are flooded to the local device.
Cause 2: Packets are modified and purge packets are triggered due to transmission faults.
Cause 3: After the local device was restarted or the IS-IS process was reset, it received LSPs with the remaining time being 0 from the local device.

Procedure

1. Check whether the local device is restarted.

If yes, this log message is informational only, and no action is required.

If the alarm is not generated, go to step 2.

2. Check whether SrcSystem is available in the log.

If yes, check the system ID of the peer device that sends the LSP and go to step 4.
If not, go to step 3.

3. View the NbrSystem field in the log, find the peer device, download the log, and check whether the LSP is sent by this device.

If yes, go to Step 4.
If no, go to Step 5.

4. Check whether the LSP is cleared on the source device.

If yes, this log message is informational only, and no action is required.
If no, go to Step 5.

5. Check the source devices that generate the LSPs with the remaining time being 0 one by one. Then, go to Step 4.

6. Collect log and configuration information, and contact Huawei technical support personnel.

7. End.
