With the goal of "IPP SDP" to have one protocol for submission and mana=
gement,
I see two paths.
1. Create an entirely redundant encoding of all the Printer MIB objects=
for
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=
ntation
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=
reat
then.

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=
h
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...;)
