nobody have a solution
Best regards

Hello Yohan,

L2TPv3 show command needs full tunnel name, which is unique per tunnel endpoint. You can see the name in the tunnel-summary, e.g.:
NX55#show l2tpv3 tunnel-summary
Sl No Tunnel Name Peer Tunnel State Tunnel Mode Estd/Total Sessions Encapsulation Proto
1 VLAN7-214-8533-sjc-1- 1 Established Active 1/1 IP
2 VLAN7-215-8533-blr-1- 1 Established Active 1/1 IP
3 VLAN7-219-8533-brq-1- 1 Established Active 1/1 IP
Total Number of Tunnels 3[/code]then you can use this name to fetch detailed tunnel stats:
NX55#show l2tpv3 tunnel VLAN7-214-8533-sjc-1-

thank' s Slava for your response

But when i type command sh l2tpv3 tunnel-summary

this means you either a) dont have any tunnel configured or b) none of the endpoints (APs) are able to reach your RFS and establish a tunnel. Please share your config
this a config of my ap 7522

and this is config of my controller

rfs4000 B4-C7-99-F9-B7-DD
use profile default-rfs4000
use rf-domain default

no local-ip-address

use l2tpv3-policy default
session vlan119 pseudowire-id 119 traffic-source vlan 119
no hostname
no router-id
establishment-criteria cluster-master
no use critical-resource
no fast-failover
you dont have any cluster configured, do you?

In that case change "establishment-criteria" from cluster-master to always under RFS tunnel configuration. Otherwise RFS will never bring the tunnel UP, since it is not part of any cluster.

are you testing with one AP and one RFS? Could you share full confg, and not just snippets, please?
with the change "establishment-criteria" from always the tunnel is established.But the ap7522 do not download the conf on rfs4000
