Impact on the System

This alarm triggers a primary/backup LSP switchover.

Possible Causes

Tunnel OAM configurations were different on the source and sink NEs of a tunnel. The possible cause was that the detection packet type or detection period may be set incorrectly.

Procedure

1.Run the display mpls oam ingress and display mpls oam egress commands to check whether OAM detection configurations on both ends are the same. - If so, go to Step 3. - If not, go to Step 2. 2.Reconfigure the OAM function on both ends. Then check whether MPLS_LSPM_1.3.6.1.4.1.2011.5.25.121.2.1.41 hwMplsOamUnknownRecovery is reported.. - If so, go to Step 4. - If not, go to Step 3. 3.Collect the alarm, log, and configuration information, and contact technical support personnel. 4.End.
