MIB-II is the most widely deployed MIB. It is installed on
hundreds of thousands of network devices. It is already
advanced on the standards track. Therefore, there was no need
for the PWG to do interoperability testing on MIB-II. (Printer
vendors still need to test their MIB-II implementations, but they can
do that testing on their own.)
Recently, there have been discussions about multiple interfaces and
changes to MIB-II. I referred the email describing these issues to
InterWorking Labs' Advisory Board (listed on www.iwl.com) to get a
second opinion. The general consensus is that the situations
are special cases and should be worked out with specialists or
consultants, but that a change to the specification was not
warranted.
Finally, deleting the requirement to implement MIB-II would
prevent us from moving to DRAFT standard, as it would be
considered a significant change.
