MPLS_LSPM_1.3.6.1.4.1.2011.5.25.121.2.1.44 hwMplsOamFail

Trap Buffer Description

The tunnel receives an OAMFAIL alarm. (SessionTunnelId=[SessionTunnelId], LocalLspId=[LocalLspId], IngressLsrId=[IngressLsrId], EgressLsrId=[EgressLsrId], IfIndex=[IfIndex], TunnelName=[TunnelName], SignalingProtocol=[SgnlPrtcl], IfName=[IfName], SignalledTunnelName=[SignalledTunnelName])

A protocol negotiation failure was detected by the OAM module.

Impact on the System

If a protection group is configured correctly, the alarm triggers a primary/backup LSP switchover.

Possible Causes

Cause 1: The OAM function was enabled only on the source or sink NEs of a tunnel.
Cause 2: The tunnel has been interrupted when the OAM function was enabled.

Procedure

1. Run the display current-configuration command to check whether OAM configurations of the ingress and egress of an MPLS tunnel are correct.

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

2. Remove OAM configuration errors.

Then check whether MPLS_LSPM_1.3.6.1.4.1.2011.5.25.121.2.1.45 hwMplsOamFailRecovery is reported.
If so, go to Step 6.
If not, go to Step 3.

3. Run the display mpls te tunnel-interface command to check whether the detected MPLS tunnel is Up.

If so, go to Step 5.
If not, go to Step 4.

4. See MPLS_LSPM_1.3.6.1.2.1.10.166.3.0.2 mplsTunnelDown and rectify the tunnel Down fault.

If the tunnel goes UP, check whether MPLS_LSPM_1.3.6.1.4.1.2011.5.25.121.2.1.45 hwMplsOamFailRecovery is reported.
If so, go to Step 6.
If not, go to Step 5.
If the tunnel Down fault persists, go to Step 5.

5. Collect alarm information and configuration information, and then contact technical support personnel.

6. End.
