RE: [EFM] OAM loop back / echo server function
As it is the case with cable modems today, the problem with this setup
is that it houses the IP stack on a management VLAN which is not exposed
through a third party access POI. I think that Link beats updates
should propagate at layer 2 across a third party access POI. Hence why
I am favouring at this time something that is in-band, rather than out
of band.

Fletcher-
I don't think this is a stupid question.
I don't think we need an IP level PING
A L2 ping would do, perhaps even better, the demarc would look for PING
type and then just swap SA & DA.
My expectation is that the demarcation device will need a MAC address My
expectation is that the demarcation device will probably end up with an
IP address in order to support:
SNMP for OA&M
Firewall services for the subscriber
(That issue is, of course, beyond our scope)
