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.
1. Run the display interface command to check whether any physical interface connected to the MPLS tunnel is shut down.
2. Run the undo shutdown command to enable the physical interface. Then check whether the alarm is cleared.
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.
