Hi everyone!
we are have a problem with enabling vc on EoMPLS circuit on Cisco ME3600x. all configuration is the same and working, we are checked ping, traceroute, ping mpls ipv4, ping mpls pseudowire, every our trying was clear and well, but when we want to see a status of vc it is still Down. after i was entered the command "sh mpls l2 vc 1517 det" after that we can see this
KAND_sw1#sh mpls l2 vc 1517 det
Local interface: Vl1517 up, line protocol up, Eth VLAN 1517 down

can anybody to answer to me, what is the error mean "Last error: Local peer access circuit is down"? i cant find any solution for resolve this error in internet. i think a problem in ME3600x, but i cant understand what i need to do.
we are using Cisco ME3600x-24cx and Cisco ASR901.
please help to me

Hello mate !
Please, paste your configurations here.
The only thing that brings to my attention is this:
"Last local AC circuit status rcvd: DOWN AC(rx/tx faults)"
Have you checked the health of your local interface ?
cheers
05-07-2015 11:31 AM
hi
can you please tell me what kind of configuration you want to see?
and second, can you please explain to me which local interface i need to check?
05-07-2015 11:34 AM
"Local interface" - Interface used as the attached circuit, the one towards the LAN
About the configuration, you can paste all things related to the vpls section
cheers

as you can see all local interface is up and working, may be reason is not here?

I never saw a L2VPN using a SVI....
Try to create a pseudowire-class on both sides, and use the loopback f both as source address for this connection (of course, if the loopbacks are reachable between each other)
somethink like... (i dont have a router to test it now)
pseudowire-class EoMPLS encapsulation mpls ip local interface loopback 0 |
Then dont forget to add the pseudowire class in the xconnect (both sides)
xconnect 10.70.1.2 1517 pw-class EoMPLS
05-07-2015 12:13 PM
when i configure pw-class i cant add "ip local interface loo 0" on both side, because in my equipments does not present this command
in this time i have this configuration on the both side:
KAND_sw1#sh run | b pse
pseudowire-class eompls
encapsulation mpls

error is still present (((
i think your and my old configuration is same right, but a problem does not bound with configuration EoMPLS, i think a location of problem is ME3600x, because in statistic of VC detail we are can see sent packets from ASR901, and not sent any packets from ME36600x
05-07-2015 12:36 PM
yeah.. forget it, that command is just for L2TPv3 (i forgot) ....
Try to make sure what is the best practice when using an interface vlan as the source, i never used it (maybe will lab it soon)
This status appears when the physical link is up/down or down/down, which is not your case !!
hope i could help
good luck
05-07-2015 10:05 PM
Hello Marat
Could you try to configure mpls ldp explicit-null on ASR901 side and see if that resolves the problem.
I would like to know what code are you running on both sides.
Please let me know if this helps.
Regards
Vinit

Were you able to resolve this issue?
This message "Last error: Local peer access circuit is down" can be due to LDP having an error processing the PW during creation.
Can you try removing the xconnect and put it back on ME3600 int vlan 1517 and if it doesn't work try to clear ldp adjacency(clear mpls ldp nei 10.70.2.66).
If clearing the LDP neighbor does not work, then please collect debugs below.
show mpls l2 vc 1517 detail.
show ssm seg id
show ssm seg id det
deb mpls l2transport vc eve
deb mpls l2transport vc status event
deb mpls l2transport vc ldp
Best Regards,

there is additional error like this :

I have the same problem please what is the solution.
09-25-2019 11:25 PM
Here Also the same error. Please any advise ?

It means something is wrong at the local interface.
