    Ron,

    I'm sorry that I have objected to the TC and enum name changes between
    Printer MIBv1 and v2 on the mailing list as you indicated in your mail note.
    I was letting our Xerox implementers do the objecting which they have done
    over the past six months (see attached) and before.

    Xerox implementers have been strongly objecting to the name changes for a
    long time. They break client and printer implementations of V1. Both
    client and server code has to be changed in order to compile with the new v2
    MIB.

    See last August mail attached and there is some that goes back two years.

    I think that some of us (including me) thought it was ok to change symbol
    names, since it didn't affect the over the wire protocol. However, such
    name changes do affect client and server code compiling with the MIB, which
    is standard implementation practice.

    Please change them back to agree with Printer MIB v1. Its fine to introduce
    TCs in V2 that didn't have TCs in V1, but don't change the names of any V1
    TCs. Same for enums.

    Thanks,
    Tom

    MIB v2

    Harry,

    We are now in the "hot seat" to get this document completed!

    Other than a couple of editorial corrections, the only real
    open issue is the name changes. I have not received any
    response from Tom regarding the impact to Xerox, so I can
    only assume that this is not an issue. (We had one vote
    for and one vote against from Xerox.)

    Ira stated that Sharp was against the new names, but I have
    no statement that it actually breaks an implementation.
    Since the current MIB draft was completed over three years
    ago and the editor during the draft development was
    employed by Sharp, it it hard to believe that these changes
    would break an implementation by Sharp!

    I agree that the name changes should not have been made,
    especially the textual conventions. But I have revised
    my implementations and going back would break my code!
    Actually, if there was a strong consensus, I am willing
    to again change my code.

    I don't see any consensus, and for this issue to surface
    three years after the draft was completed, makes it seem
    more like a religious issue than a real technical problem.
    The weak response on this subject indicates that the
    majority of WPG members don't care.

    As chairman of this project, I am closing this issue. We
    must move forward and get this document published.

    As to incorporation of the Finisher MIB, this will surely
    cause a major problem with the IETF. We are going to
    have enough to worry about due to the changing Area
    Director. (My real concern with the Finisher MIB is the
    attribute mechanism and the negative response it received
    in the Job MIB.)

    When do you estimate the editing changes can be incorporated
    and the document submitted as an Internet-Draft? I can
    assist in any editing changes if necessary.

    Hi folks,

    RFC 2790 - Host Resources MIB v2 (March 2000)
    - IETF Draft Standard status

    This was posted last week (14 March 2000) but got past
    me until it showed up in the RFC Index today.

    So now it's time to get on with Printer MIB v2.

    I urge that we fold the text of Finisher MIB into the
    Printer MIB v2 text (after all it completes the model
    in original Printer MIB, RFC 1759, March 1995) and
    NOT publish Finisher MIB as a separate RFC.

    I also urge that we press on as quickly as possible
    with publishing a definitive text for Printer MIB v2
    (with the approved additions from July 1999 for new
    generic alerts and 'chIPP' specification) and move it
    to PMP WG last call and send it onward for IESG last
    call. More than one vendor has already shipped a
    product with Printer MIB v2 new objects implemented.

    Remember that since the bar is now *very* high for
    advancement to Draft Standard, the Printer MIB v2
    MUST be published at Proposed Standard and convincing
    proof of interoperable implementations of EVERY object
    and object group must be presented to the IESG and
    publicly posted before we can request movement to
    Draft Standard status.

    Cheers,

    Happy New Year! Hope everyone had a very good holiday!

    (Now back to work)

    I need to know, ASAP, if these enum name changes really have
    an impact on anyone's system. So far there has been no response
    to Mike Elvers message.

    Now that the holidays are over, I would like to get the Printer MIB
    into a 'ready to go' stage, so that it can progress as soon as the HR
    MIB is approved. Please review this message and if any of these
    changes have an impact, please reply stating which items are a
    problem. No response is assumed to be a 'no problem" reply (but
    it would be nice if some 'no problem' replies were received ;-)

    The deadline is January 24th (3 weeks). No changes will be made
    to the MIB unless a reply is received to a specific item.

    Subject: PMP> TC definitions is Printer MIB II

            PMP,

            I have been looking at the latest draft of the Printer MIB and I
    have observed that many existing enumeration values have had their names
    changed or have been deleted (without first having been deprecated). Does
    this not present a significant backward compatibility problem for management
    stations?

            I have also noticed that the enumeration definitions have been
    removed from the object definitions and placed in their own TC defintions
    except for the following objects:

            prtConsoleDisable
            prtMarkerAddressabilityUnit

            Is there something special or unusual about these two that the
    enumeration values have not be extracted into a new TC type definitions and
    the objects defined with the TC definition?

            Thanks,

            Mike
