2. Verify the connectivity of the PW.
Run the ping vc command on the U-PE, and you can see that the connectivity of the PW
is normal. Take the display on U-PE1 for example.
<U-PE1> ping vc vlan 100 control-word remote 200
Reply: bytes=100 Sequence=1 time = 740 ms
Reply: bytes=100 Sequence=2 time = 90 ms
Reply: bytes=100 Sequence=3 time = 160 ms
Reply: bytes=100 Sequence=4 time = 130 ms
Reply: bytes=100 Sequence=5 time = 160 ms
--- FEC: FEC 128 PSEUDOWIRE (NEW). Type = vlan, ID = 100 ping statistics ---
5 packet(s) transmitted
5 packet(s) received
0.00% packet loss
round-trip min/avg/max = 90/256/740 ms
3. Collect path information about the PW.
Run the tracert vc command on the U-PE, and you can collect information about the LSRs
where the PW passes through and the egress PE. Take the display on U-PE1 for example.
<U-PE1> tracert vc vlan 100 control-word remote 200 full-lsp-path
TTL Replier Time Type Downstream
0 Ingress 10.1.1.2/[1025 ]
1 10.1.1.2 100 ms Transit 20.1.1.2/[3 ]
2 20.1.1.2 60 ms Transit
3 30.1.1.2 80 ms Transit 40.1.1.2/[3 ]
4 40.1.1.2 150 ms Egress
<U-PE1> tracert vc vlan 100 control-word remote 200
TTL Replier Time Type Downstream
0 Ingress 10.1.1.2/[1025 ]
2 20.1.1.2 60 ms Transit
4 40.1.1.2 110 ms Egress
If the S-PE is disabled from responding to an MPLS Echo Request packet, the configuration
on the S-PE is as follows:
[S-PE] undo lspv mpls-lsp-ping echo enable
Run the tracert vc command on the U-PE to collect information about LSRs and egress
PE, the U-PE displays the timeout information because it does not receive the reply packet.
Take the display on U-PE1 for example.
<U-PE1> tracert vc vlan 100 control-word remote 200 full-lsp-path
TTL Replier Time Type Downstream
