Down Reasons        : Control word not match

Common fault causes and solutions are as follows:

BFD session for PW down—The BFD session for PW detection is down. In this case, use the display bfd session command to view the reasons for the BFD session down, and then correct the BFD configuration or troubleshoot the physical link and link quality issues accordingly.

BGP RD was deleted—The BGP RD has been deleted. In this case, execute the route-distinguisher route-distinguisher command in auto-discovery cross-connect group view.

BGP RD was empty—No BGP RD is configured. In this case, execute the route-distinguisher route-distinguisher command in auto-discovery cross-connect group view.

Control word not match—The control word configuration on the two ends of the PW is inconsistent. In this case, configure the same control word setting on the two ends of the PW by using the control-word enable command in the PW class specified for the PW.

Encapsulation not match—The encapsulation types on the two ends of the PW are inconsistent. In this case, configure the same PW data encapsulation type on the two ends of the PW by using the pw-type command in the PW class specified for the PW.

LDP interface parameter not match—The LDP negotiation parameters on the two ends of the PW are inconsistent. In this case, configure the same VCCV CC type on the two ends of the PW by using the vccv cc command in the PW class specified for the PW. Or, configure the same CEM class settings for the CEM interfaces used by the two ends of the PW.

Non-existent remote LDP PW—The remote device has deleted the LDP PW. In this case, reconfigure the PW on the remote device.

Local AC Down—The local AC is down. In this case, verify that the configuration of the AC interface is correct and the state of the AC interface is up on the local device.

Local AC was non-existent—No local AC is configured. In this case, configure a local AC and associate it with the VSI.

MTU not match—The MTU configuration on the two ends of the PW is inconsistent. In this case, configure the same MTU on the two ends of the PW or use the mtu-negotiate disable command to disable PW MTU negotiation.

Remote AC Down—The remote AC is down. In this case, verify that the configuration of the AC interface is correct and the state of the AC interface is up on the remote device.

4.If the AC and PW are both up, use the display l2vpn forwarding pw verbose command to display whether the PW has forwarding information (Tunnel NHLFE IDs—NHLFE IDs of the public tunnels that carry the PW).

<Sysname> display l2vpn forwarding pw verbose

VSI Name: aaa

Link ID: 8

PW Type         : VLAN                  PW State : Up

In Label        : 1272                  Out Label: 1275

MTU             : 1500

PW Attributes   : Main

VCCV CC         : Router-Alert

VCCV BFD        : Fault Detection with BFD

Flow Label      : Send

Tunnel Group ID : 0x960000000

Tunnel NHLFE IDs: 1034

MAC limit       : maximum=2000   alarm=enabled   action=discard

If a Tunnel NHLFE ID is displayed, go to step 6.

If no Tunnel NHLFE ID is displayed, go to step 5.

5.Use the display mpls lsp command to verify whether there is an LSP whose FEC is the remote IP address of the PW. This LSP is the tunnel that carries the PW. If the LSP tunnel does not exist, establish the tunnel first.

<Sysname> display mpls lsp

FEC                         Proto    In/Out Label    Out Inter/NHLFE/LSINDEX

100.100.100.100/24          LDP      -/1049          GE1/0/1

6.If the issue persists, collect the following information, and then contact Technical Support for help.

Execution results for the previous steps.

Configuration file, log messages, and alarm information of the device.

7.Use the display diagnostic-information command to collect diagnostic information.
