Parameters

Name Meaning

oid

Indicates the MIB object ID of the alarm.

sysInstance

Indicates the ID of the IS-IS process.

sysInstanceofLevel

Indicates the ID of the IS-IS process.

sysLevel

Indicates the IS-IS level:
  • 1: Level-1

  • 2: Level-2

sysInstanceofInterface

Indicates the ID of the IS-IS process.

circuit

Indicates the index of the interface.

ifIndex

Indicates the index of the interface.

circuitIfIndex

Indicates the IF index of the interface.

pduLspId

Indicates the ID of the LSP.

pduRemoteRouterID

Indicates the router ID of the remote system.

ifName

Indicates the name of the interface.

Impact on the System

1. If the trap triggered by the restart of the local switch, services will not be affected.

2. If the trap is generated frequently, IS-IS routes are affected and packets may not be forwarded.

Possible Causes

1. The local switch did not refresh its LSPs in time. As a result, Purge packets were generated after LSPs were aged and flooded to the local switch.

2. The packet was modified and Purge packets were generated because of transmission failure.

3. The local switch was restarted and then received the LSP with the system ID as local IS-IS and the lifetime as 0 from the neighbor.

Procedure

  1. Check whether the local switch is restarted.

    • If so, it indicates that this trap message is informational only, and no action is required. Go to Step 4.

    • If not, go to Step 2.

  2. Check whether the IS-IS authentication configuration is modified and hence the Purge packets are generated and the trap is triggered.

    • If so, it indicates that this trap message is informational only, and no action is required. Go to Step 4.

    • If not, go to Step 3.

  3. Collect the trap information, log information, and configuration of the switch, and contact technical support personnel.
  4. End.
