[j-nsp] Ethernet OAM, specifically CFM

[Keegan Holley]

CFM just performs a continuity check so I'm not sure it will help you
here.  In other words it just checks if the CFM instance on the switch can
talk to the CFM instance on the router.  If I understand your question
correctly you're trying to verify an access point leading to a customer and
not your MX.  If there is only one access port per VLAN interface can you
move it down to the switch?
