Parameters

Name	Meaning
oid	Indicates the MIB object ID of the alarm.
VsiName	Indicates the name of a VSI.
PwId	Indicates the ID of a PW.
RemoteIp	Indicates the IP address of the remote peer.
PwType	Indicates the type of a PW: 1: normal 2: other
HWL2VpnStateChangeReason	Indicates the cause of the VC status change.
SysUpTime	Indicates the time for system startup.
TunnelPolicyName	Indicates the name of a tunnel policy.
TunnelType	Indicates the type of a tunnel.
SessionTunnelId	Indicates the ID of a tunnel.

Impact on the System

VPLS Services will be interrupted and the traffic will be blocked.

Possible Causes

The status of the physical link or the configurations on both ends of a link was changed.

Procedure

Run the display vsi name vsi-name verbose command to check the VSIs on the local device and the peer device. In the case of the LDP VSI, check the VSIs with the same VSI ID. In the case of the BGP VSI, check the VSIs with the same VPN target.
- If the AC interface (in the field of Interface Name in the command output) is Down, go to Step 2.
- If the status of the VSI is Admin Down, go to Step 3.
- If the MTUs or the encapsulation types on the local and peer devices are inconsistent, go to Step 4.
- If the PW does not exist, go to Step 5.
- If the PW is Down, go to Step 12.
Restore the AC interface to Up, and check whether the alarm is cleared.
- If so, go to Step 14.
- If not, go to Step 1.
Run the undo shutdown command in the VSI view to check whether the alarm is cleared.
- If so, go to Step 14.
- If not, go to Step 1.
Run the mtu mtu command in the VSI view to set the MTUs of the VSIs on both ends to be consistent. Run the encapsulation command to set the encapsulation types on both ends to be consistent. Then, check whether the alarm is cleared.
- If so, go to Step 14.
- If not, go to Step 1.
Run the display vsi name vsi-name verbose command to check the PW signaling.
- If it is LDP, go to Step 6.
- If it is BGP, go to Step 7.
Run the display vsi name vsi-name verbose command to check whether the session on the VSI peer is Up.
- If not, go to Step 8.
- If so, go to Step 9.
Run the display bgp peer command to check whether the BGP connection with the peer in the VPLS address family is established.
- If so, go to Step 13.
- If not, go to Step 10.
Run the display mpls ldp session command to check whether the session of the peer is operational.
- If so, go to Step 13.
- If not, go to Step 11.
Run the display vsi name vsi-name verbose command to check whether the session of the VSI peer has the tunnel ID.
- If so, go to Step 12.
- If not, go to Step 11.
Configure the BGP connection to be established, and check whether the alarm is cleared.
- If so, go to Step 14.
- If not, go to Step 13.
Check whether the interface on the public network is Down. Set the interface on the public network to be Up, and then check the LDP configuration. Run the display mpls ldp session command to check that the session becomes operational, and then check whether the alarm is cleared.
- If so, go to Step 14.
- If not, go to Step 13.
Check the configurations of the routes and public network interfaces one by one. If the configuration is correct, go to Step 14. If the configuration is incorrect, restore the configuration and check whether the alarm is cleared.
- If so, go to Step 14.
- If not, go to Step 13.
Collect alarm information and configuration information, and then contact technical support personnel.
End.
