IEEE Report

Donna summarized the status of the IEEE 802.3 Management work as
follows:


   o Repeater Management Draft

      -  Passed 2nd IEEE 802.3 confirmation ballot.
      -  Forwarded to TCCC ballot.
          * Several comments.
          * All but one easily resolved.
          * Will go for TCCC confirmation ballot this month.


   o MAU Management Draft

      -  Few changes from Feb-July 92 (through 3 meetings).
      -  Going for first 802.3 ballot.


   o 802.3 Layer Management (like Ethernet-like Interfaces MIB)

      -  Being rewritten in ISO GDMO format.

                                   1





      -  Some rearrangement of conformance packages.
      -  Frank Kastenholtz has details.


Repeater MIB Status

The Repeater MIB had been updated after the last meeting, circulated to
the Working-Group's mailing list, updated according to the few comments
received, and forwarded to the IESG Area Director for Network Management
with the Working Group's recommendation for advancement to Proposed
Status.  It was currently awaiting consideration by the Network
Management Directorate.

Implementation experience feedback from attendees brought forth the
following comments:


   o The nonDisruptiveSelfTest description should be clarified to allow
     returning ``ok'' after doing only a trivial test.

   o The setting of rptrReset to cause the Repeater to reset should
     allow the agent to delay the reset (for a short period) if it so
     wishes (e.g., to allow the SNMP Response to be transmitted.)

   o It was suggested that the enumerated values autoPartitioned(1) and
     notAutoPartitioned(2) of the object rptrPortAutoPartitionState be
     changed to have the normal condition (notAuthPartitioned) have the
     value (1), since the normal condition of most other ``state'' MIB
     objects has the value (1).


It was agreed that the latter was preferable, but only if the MIB could
be changed without causing any further delay in the approval of the MIB.
The others would be remembered for updating the MIB at a later date
(e.g., when moving from Proposed to Draft status).

Discussion of MAU MIB

A first draft of an IETF MAU MIB had been distributed at the last
meeting, and a second draft mailed to mailing list early June.  Donna
presented the following overview of MAU management status and issues:


   o 802.3 Medium Attachment Unit (MAU) attaches repeater port or
     Ethernet-like interface to the local network medium.

   o MAU types include 10BASE5 (thick coax), 10BASE2 (thin coax),
     10BASE-T (twisted pair), FOIRL and 10BASE-F (fiber optic).

   o MIB information includes MAU type, link status, jabbering.

At the previous meeting, the issue of how to instantiate MAUs had been
briefly discussed, and a preliminary decision made to have separate MIB
objects for Etherlike Interface MAUs and Repeater MAUs.  Before this
meeting, Frank Kastenholz, editor of the Etherlike Interfaces MIB had
expressed no interest in doing an Etherlike Interface MAU MIB. Thus,
this meeting decided to develop one MIB having both a table for Repeater
MAUs indexed by ``group.port.mau'', and a table for Etherlike Interface
MAUs indexed by ``interface.mau'', even though these tables would be
remarkably similar except for their indexing.

The meeting then proceeded with a walk-through of the objects contained
in the current MAU MIB draft (containing only the table indexed for
Repeater MAUs).  The following issues were raised:


   o The optional grouping in this MIB is slightly different to IEEE's.
     No one had any specific comments, but were invited to think about
     this issue and post any comments to the mailing-list.

   o The need for having multiple MAUs on a port was discussed, and it
     was suggested that choice of media, and having a backup MAU were
     two reasons for this.  Thus, it was not thought to be necessary to
     allow there to be 65535 MAUs on each port !!  It was agreed that
     (1..9) was a good range, since this allowed the MAU-number to be
     displayed as a single digit.

   o It was suggested that rpMauType should be an OBJECT IDENTIFIER, and
     that this MIB should define values for the various types (i.e., not
     use IEEE-defined values).

   o The overlap between rpLostMedias with an object in the
     Ethernet-interface MIB was discussed.  Donna agreed to check
     further into this.

   o An elaboration of the description of Jabber counters was requested,
     giving further definition and/or an IEEE reference.

   o A number of other minor editorial changes were suggested and
     agreed.


Future Plans

A branch within the experimental subtree (as defined by the Internet
SMI) would be requested for use by this MIB.

The editors agreed to produce an updated draft of the MAU MIB and mail
it to the list for comments.  After incorporating any further comments,
it would be posted as an Internet Draft.  If no further comments were
forthcoming, the mailing-list would be polled to determine if there was
consensus approval that the MIB was ready to be forwarded with the
Working Group's recommendation for advancement to Proposed Standard
