Parameters

Name	Meaning
oid	Indicates the MIB object ID of the alarm.
InterfaceIndex	Index of the interface used as the table index.
InterfaceIndex	Index of the interface reported to the network management system as a parameter.
SvcId	Indicates the ID of an SVC.
SVcType	Indicates the type of an SVC: 0: Initial value 1: FR 2: ATM AAL5 3: ATM cell relay 4: VLAN 5: Ethernet 6: HDLC 7: PPP 9: ATM cell VCC 10: ATM cell VPC 11: IP-layer 2 (used for heterogeneous IP-interworking between Huawei devices and non-Huawei devices) 12: ATM, 1-to-1 VCC cell mode 13: ATM, 1-to-1 VPC cell mode 14: ATM, AAL5 PDU VCC Transport 64: Heterogeneous IP-interworking
PeerAddress	Indicates the IP address of a peer.
SvcInboundLabel	Indicates the incoming label of an SVC.
SvcOutboundLabel	Indicates the outgoing label of an SVC.
HWL2VpnStateChangeReason	Indicates the cause for the SVC status change.
InterfaceName	Indicates the interface name.
TunnelPolicyName	Indicates the name of a tunnel policy.
ActiveState	Indicates the status of active.
TunnelType	Indicates the type of a tunnel.
SessionTunnelId	Indicates the ID of a tunnel.

Impact on the System

The SVC service is interrupted and the traffic is blocked.

Possible Causes

The local or peer AC interface went Down.

The public network tunnel was faulty.

Procedure

Run the display mpls static-l2vc interface interface-type interface-number command to check whether the AC goes Up.
- If so, go to Step 3.
- If not, go to Step 2.
The SVC status can be Up if two conditions are met. That is, the AC status is Up and the tunnel is selected.
Check whether the AC interface goes Down.
- If so, rectify the fault and ensure that the AC interface goes Up. Then, check whether the fault is rectified. If so, go to Step 7; if not, go to Step 3.
- If not, go to Step 3.
View the command output in Step 1 to check whether the number of tunnels in the VC tunnel/token info field is 0.
- If so, go to Step 4.
- If not, go to Step 7.
Run the display tunnel-info all command to check whether there is information about the LSP tunnel with the destination address being the address of the peer PE.
- If so, go to Step 7.
- If no, go to Step 5.
Check and rectify the configuration of the public network interface. Check whether the fault is rectified.
- If so, go to Step 7.
- If not, go to Step 6.
Collect alarm information and configuration information, and then contact technical support personnel.
End.
