MPLS_LSPM/2/hwMplsOamAis_active

Message

MPLS_LSPM/2/hwMplsOamAis_active: The tunnel receives an AIS alarm. (SessionTunnelId=[SessionTunnelId], LocalLspId=[LocalLspId], IngressLsrId=[IngressLsrId], EgressLsrId=[EgressLsrId], TunnelName=[TunnelName], SignalingProtocol=[SgnlPrtcl], SignalledTunnelName=[SignalledTunnelName])

Description

Services were interrupted on the service layer.

Parameters

Parameter Name	Parameter Meaning
SessionTunnelId	Indicates the tunnel ID.
LocalLspId	Indicates the local LSP ID.
IngressLsrId	Indicates the LSR ID of the ingress node.
EgressLsrId	Indicates the LSR ID of the egress node.
TunnelName	Indicates the tunnel name.
SgnlPrtcl	Indicates the tunnel protocol ID. Ranges: 1:RSVP 2:STATIC 3:CRSTATIC
SignalledTunnelName	Tunnel alias.
LsrRole	Indicates the tunnel LSP role. 1: Ingress 2: Transit 3:Egress

Possible Causes

Cause 1: The interface on the service layer is shut down and the service layer is interrupted so that an AIS PDU is sent to notify the client layer.

Cause 2: The MPLS tunnel is congested on the service layer and the service layer is interrupted so that an AIS PDU is sent to notify the client layer.

Procedure

1. Run the display interface command to check whether any physical interface connected to the MPLS tunnel is shut down.

If so, go to Step 2.
If not, go to Step 4.

2. Run the undo shutdown command to enable the physical interface. Then check whether the alarm is cleared.

If so, go to Step 5.
If not, go to Step 3.

3. If all configurations are correct, the MPLS tunnel is congested. Then go to Step 4.

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

5. End.
