All,
I do not share most of Randy's concerns. I see the printer MIB as an
agreed upon standard way of representing a printer. I believe it is rich
enough to satisfy IPP's "host to device" needs. I am not concerned about
circumventing standard SNMP security mechanisms. There are currently
embedded web servers that also update the MIB objects. I see three views
into the same data objects. The three are SNMP, Web Access and IPP. The
implementers must insure that the model is not corrupted by multiple access
methods. I see no difference between the "multiple view" scenario and
multiple SNMP managers manipulating the printer object. I am also not
concerned by the ability for IPP to carry SNMP syntax. As far as I know
there is nothing in SMI that cannot be represented in IPP.
The areas that I do have some concerns in is the definition of the
req/resp for the printer MIB access operations. The other feature I am
concerned with is the overlap of notification methods in SNMP and IPP. I
have not yet seen if the overlap needs to be addressed. If the overlap
needs to be addressed how will it be resolved?

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
which
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...;)
