Re: [EFM] OAM loop back / echo server function

["Geoff Thompson" <gthompso@xxxxxxxxxxxxxxxxxx>]

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)
