# Execute the display minm connection command on BEB-PE. You can see the MAC-in-MAC uplink
information of the VSI aaa. The information means that BEB-PE has learnt the B-MAC information
from BEB, its peer device.

Troubleshooting VPLS

Symptom
The VPLS PW is not up.
Analysis
The public network LSP tunnel is not established.
•
The extended session is not working normally.
•
• A private network interface is not bound with the corresponding VPLS instance or the private
network interface is not up.
The AC port at the private network side is not up.
•
Negotiation of VPLS parameters, such as PW ID, MTU, and transport mode, is failed on the two
•
peers.
Solution
Check the routing tables of the PEs to see whether a route is available between the two PEs. Check
•
whether each device can ping the loopback interface of the peer and whether the LDP session is
normal.
• Check whether any extended session configuration command is missing at either side.
View the private interface status by using the display interface command. Make sure the private
•
interface is up.
View the current configuration by using the display current-configuration command. Make sure that
•
the two peers have the same PW ID and transport mode.
