Fault analysis
Check the label of the static VC on the PE of the opposite end:
[PE2] display mpls static-l2vc
Total svc connections: 1, 1 up, 0 down
Client Interface : Ethernet1/0/1 is up
AC Status : up
VC State : up
VC ID : 0
VC Type : ethernet
Destination : 1.1.1.1
Transmit VC Label : 200
Receive VC Label : 100
Control Word : Disable
VCCV Capability : Disable
Tunnel Policy Name : --
Traffic Behavior : --
PW Template Name : --
Create time : 0 days, 0 hours, 0 minutes, 17 seconds
UP time : 0 days, 0 hours, 0 minutes, 17 seconds
Last change time : 0 days, 0 hours, 0 minutes, 17 seconds
You can see that the label configuration on the local PE is different from that of the peer.
CEs can communicate after the following configuration:
[PE1-Ethernet2/0/1] mpls static-l2vc destination 2.2.2.2 transmit-vpn-label 100
receive-vpn-label 200
Troubleshooting procedure
Step 1 Delete the static VC on one end and reconfigure it.
—End
Summary
When the label of the static VC is incorrect, the data cannot forward normally even though the
VC is Up.
When you configure the static VC, note the following:
• The local transmit-vpn-label and the remote receive-vpn-label are consistent.
• The local receive-vpn-label and the remote transmit-vpn-label are consistent.
