Trap Buffer Description

The tunnel receives a MEP alarm. (SessionTunnelId=[SessionTunnelId], LocalLspId=[LocalLspId], IngressLsrId=[IngressLsrId], EgressLsrId=[EgressLsrId], TunnelName=[TunnelName], SignalingProtocol=[SgnlPrtcl])

MEP IDs on two ends of an MPLS tunnel were different.

Impact on the System

This alarm affects the ME status, triggers a CC alarm, and triggers a primary/backup LSP switchover.

Possible Causes

IDs of the ingress and egress MEPs are different.

Procedure

1. Run the display current-configuration command to check whether IDs of the ingress and egress MEPs are the same.

If so, go to Step 3.
If not, go to Step 2.

2. Set a same ID for the ingress and egress MEPs.

Then check whether MPLS_LSPM_1.3.6.1.4.1.2011.5.25.121.2.1.27 hwMplsOamMepRecovery is reported.
If so, go to Step 4.
If not, go to Step 3.

3. Collect the trap information, log information, and configuration information, and then Collect alarm information and configuration information, and then contact technical support personnel..

4. End.
