RE: [EFM] RE: OAM functionals

A lot of the detailed management functions are product and vendor specific.

The EFM standard should cater only for the basic management functions for
test and possibly port enable/disable, but some would argue that one is
product specific and a step too far.

The EFM standard should provide the vendor with a channel down which to run
their own management application in whatever protocol they choose be it UDP
with SNMP or something proprietary. The vendors that talk to their customers
(and some vendors even listen to the replies) will probably do better than
those that don't :-).
