RE: [802.1 - 1083] FW: [Bridge-mib] Connectivity Fault Management MIB

Let me try a few (immediate and obvious answers).
But I am not answering all... and of course I am not
the author/editor of the MIB.

Norm and I were discussion the security considerations and part
of that was/is the fact that an interface may have disappeared 
over a reboot. In that case, Norm suggested to use zero for
ifIndex. Seems fine to me. Syntax then will have to be 
changed to InterfaceIndexOr Zero.

This will create VERY long OIDs.
Possibly so long that a CREATE will not fit in one SNMP PDU.

same here

That would probably work also.
Not sure why it is so much simpler. But I could live with it.

I will leave that to Norm or David (MIB editor)
