Hello Andras,
Long shot but you might need to change the revision for echo packets on NX-OS to revision 3 (default is 4).1.configure terminal 2.mpls oam 3.echo revision {3 | 4} 4.echo vendor-extension 5.exit http://www.cisco.com/en/US/docs/switches/datacenter/sw/5_x/nx-os/mpls/configuration/guide/mp_mpls_ping.html#wp1078363
Interesting read, thanks. But unfortunately that does not change the behaviour.
Best Regards, Bernhard
