With the goal of "IPP SDP" to have one protocol for submission and mana=
I see two paths.

1. Create an entirely redundant encoding of all the Printer MIB objects=
this new SDP protocol
2. Provide a way for the SDP to access the current MIB OIDs.

Given that many (most?) of us already have the Printer MIB data represe=
in our printers, I prefer (2).

I can see Randy's point if the desire was to keep print submission and
management separate, but I think, if you accept the premise of SDP in t=
he first
place, you must abandon this approach.

As for security, this seems like an odd reasoning. Security was always =
one of
SNMP's weak points and something IPP has struggled to achieve. Besides,=
I don't
think Scott has recommended and SETs to the OIDs.

One of the highlights of SENSE I remember Jay telling us about was that=
, with
one query, he could get the whole Printer MIB. It didn't seem like a th=

I have some reservations about using the concept of using IPP to
encapsulate OID to access SNMP MIB objects. I think we should be very
careful about the scope and requirements for such a capability. The
biggest problem I guess I have with this is that we MUST make sure that=

IPP is not used to circumvent or hack access to manageable objects whic=
might otherwise be secured by standard SNMP security methods. There are=

other considerations such as the definition of request and response
attributes, and whether or not we have a rich enough value syntax to
describe current SMI data objects.
I could go on but its Friday night and I'm getting dirty looks...;)
