Hi David,
Thanks for looking at our proposal for an IPP channel
in the Printer MIB. Yes, it does result in multiple
IPP channels if multiple authentication or security
regimes are supported. We (guessed) this would be
considered simpler in the MIB than the IPP alternative.
In IPP/1.1, there are three parallel ordered multi-valued
attributes:
printer-uri-supported
uri-authentication-supported
uri-security-supported
These would result in one VERY large channel info entry
(which wouldn't really work with MIB limits on string
lengths). So we opted for multiple channel entries.
The conformance requirements around the four channel
attributes were specifically sync'd up with the latest
discussion on IPP WG Telecons, so we think it's pretty
close - Tom has pointed out a bad sentence on 'http:'
and explicit port numbers - I'm pondering rewrite or
simple deletion.
Cheers,
