Minutes of the 100VG-AnyLAN MIB BOF (VGMIB)

VGMIB met in Danvers as a BOF and has since become a working group.

The VGMIB BOF was chaired by John Flick.  Jeff Johnson volunteered to
take minutes.  The meeting began with a presentation of the proposed
agenda.  The agenda was accepted as presented.

A quick introduction of the reasons for having the BOF was given.  Two
key questions need to be answered:


  1. Is there interest in a VG MIB?
  2. Are there any implementors, both agent and NMS, that would use it?


The Current Status of 802.12

John outlined the current status of 802.12 in the IEEE. 802.12 has
passed LMSC Sponsor Ballot, and has been approved by the LMSC Executive
Committee to go to the IEEE Standards Board pending a successful
recirculation ballot.  It is expected to become a standard in the
June-July timeframe.


A Proposed Charter

John presented a proposed charter.  The output of the proposed working
group is to be two MIB modules; one for VG Interfaces and one for VG
Repeaters.  The input for these two MIBS is the GDMO from the 802.12
specification, with the existing 802.3 interface and repeater MIBs
providing reference.  In addition, vendors are to be solicited for
additions to the MIBs.  Two Internet-Drafts have already been
distributed:


     draft-flick-interfaces-mib-00.txt
     draft-flick-repeater-dev-mib-00.txt


A mailing list has already been established:
vgmib[-request]@hprnd.rose.hp.com.  There will soon be an FTP site,
ftp://ftp.rose.hp.com.  Discussion of the two Internet-Drafts is already
underway on the mailing list.

A working group schedule was proposed:


   o 1 May 95 -- Charter working group
   o 31 May 95 -- Deadline for proprietary MIB module submissions
   o 30 June 95 -- Post initial Internet-Drafts
   o July 95 -- Working group meeting at Stockholm IETF (if needed)
   o 31 August 95 -- Post updated Internet-Drafts
   o 29 September 95 -- Submit final Internet-Drafts to the IESG for
     consideration as Proposed Standards


Initial consensus was that the schedule was too aggressive.  There was
concern that a delay by IEEE in standardizing 802.12 would have a ripple
effect on the IETF effort.  John Flick pointed out that although 802.12
has undergone revision, the network management portion is stable, and
should not be a factor.  There was a discussion as to whether or not
there was even enough interest in the community.  Only three companies
represented at the BOF were interested in the MIBS; most of the
attendees were observers.  There was some discussion as to whether or
not a working group was in order.  The area director requested that the
chartering issue be taken off-line.


Internet-Draft Overview

John gave a group-by-group overview of the two Internet-Drafts.  There
was some discussion and clarification of MIB objects, then there was the
inevitable discussion of repeater ID. Most attendees either do not
implement the 802.3 Repeater MIB (RFC 1516), or else they implement a
proprietary MIB, mirroring RFC 1516, which has object instances which
include a repeater ID. This is due to the fact that most management
applications do not support multiple repeater communities, and hence a
proprietary MIB is required to manage the device.  It was then discussed
that the VG Repeater MIB should be consistent with the 802.3 Repeater
MIB. Since the HUBMIB Working Group is reforming to evaluate 100BaseT,
and since that is where the initial repeater ID discussions took place,
perhaps that is where the discussion should take place again this time.
There was also some discussion on mapping repeater ports to ifEntrys,
but that work is also probably best left to the HUBMIB Working Group.


Summary

John summarized the BOF. The area director and John Flick were to meet
to discuss chartering.  The group would address the VG Interfaces MIB
first.  The group would then wait for the HUBMIB Working Group to
resolve the repeater ID and port-to-interface mapping, at which time the
VGMIB Working Group will mirror their work.  The meeting then adjourned.

Following the meeting, John Flick, Jeff Johnson, and Kaj Tesink met with
the Network Management Area Director, Dierdre Kostick.  Dierdre said she
would charter the working group with Jeff Johnson as chair and John
Flick as editor.  The working group is to concentrate first on the
Interfaces MIB, and then await resolution of repeater issues from the
HUBMIB Working Group before finalizing work on the VG Repeater MIB.
