Minutes of the Ethernet MIB Working Group (ETHERMIB)

The Ethernet MIB Working Group met at the Santa Fe IETF meeting on
Thursday, November 21, 1991.

The first order of business was to review the administrative issues
surrounding the Working Group:


  1. The charter and the ``Pax Davin'' were reviews and discussed at
     length.  The fact that we will strictly adhere to the rules of
     charter and the ``Pax Davin'' was openly discussed and agreed to by
     all present.

  2. The Working Group decided to try to have the documents required by
     the charter ready for publication at the same time as the MIB is
     put forward for Draft Standard status.  This would be in about 6
     months.  These two documents are:


     (a) An explanation for the assignment of MANDATORY status to
         optional 802.3 variables, and

     (b) An implementation report on the MIB variables.

     (c) A mailing list will need to be created.
         [This has been done -- [e-mail].]


After discussing administrative issues, the Working Group turned its
attention to the MIB itself.  The following items were discussed (thanks
to Anil Rijsinghani of DEC for his notes of the meeting).  Any changes
to the MIB will be made to the version to be put forward for DRAFT
STANDARD status.


  1. The Working Group discussed the text in the MIB which allows an
     implementation to return 0 for counters for which the underlying
     events are not counted.  It was realized that this wording makes it
     impossible to disambiguate the two cases of not implementing a
     counter and and 0 occurences of the underlying event.

     The Working Group discussed the issue and a vote was taken on it.
     The group decided to remove the offending text from the document.
     The Working Group realized that for variables to which this text
     applies, there are four alternatives which should apply:


                                   1





     (a) Delete the variable from the MIB entirely as its utility has
         not been demonstrated by wide implementation experience,

     (b) Move the variable into a separate optional MIB Group,

     (c) The implementor must figure out some way to support the
         variable, and

     (d) The implementor would not implement the variable, return
         noSuchName errors whenever the variable is accessed and not
         claim compliance to the MIB.

  2. The possibility of an 802.3 specific (as opposed to DIX Ethernet
     specific or common to both) mib group was discussed.  It was
     decided to continue this discussion on the mailing list.

  3. The dot3StatsExcessiveDeferrals object is implemented in only one
     chip out of 14 studied by Anil Rijsinghani.  It should either be
     made optional or removed from the MIB. The other mandatory objects
     are implementable with commonly available chips and supporting
     software.

     This will be considered for further study on the mailing list.

  4. The TDR definition in the MIB is not sufficient, given that IEEE
     802.3 does not define this object.  It does not describe the two
     conditions under which the object is defined, and how to
     distinguish between them (short and open cable faults).  Anil
     Rijsinghani will contribute text to clarify this.
