Minutes of the ATM MIB Working Group (ATOMMIB)


SONET MIB

The current Internet-Draft, ietf-draft-atommib-sonet-01.txt, is
considered complete.  The meeting participants decided unanimously to
recommend this Internet-Draft to the area director for further
processing by the Network Management Area Directorate (NMDIR) and the
IESG as a Proposed Standard.


ATM MIB

   o Use of ifTable for the ATM Level

     The mapping in the current Internet-Draft was agreed upon with a
     minor amendment to the mapping of ifOutErrors.

   o Use of ifTable for AAL5

     A new approach was adopted.  The detailed text will be worked out
     on the mailing list.  The approach treats AAL5 entities in switches
     as connected with the switch through a virtual interface; in hosts
     the AAL5 level is directly stacked on the ATM level.  The approach
     also requires a small AAL5-specific table in the ATM MIB for AAL5
     error counters.  Explanatory text on this subject will also be
     included in the specification.

   o Modeling of ATM Connections

     The small group tasked at the Amsterdam meeting has identified two
     approaches.  Ted Brunner identified the approaches:

      1. Proposal Bob - Similar to what is contained in the current ATM
         MIB and Frame Relay MIB Internet-Drafts.
      2. Proposal Dave - Takes a common approach for hosts, switches,
         and services.

     The meeting participants decided to proceed with an approach,
     dubbed ``Henrietta'', that combines the strong points of Dave and
     Bob.  The current MIB will be amended as appropriate.  Detailed
     text as to how to do orderly connection setup will also be
     included.

   o Any Other ATM MIB Issues

     The proposal, to combine the separate VPL and VCL tables into a
     single table, and the VCC and VPC tables into a single table, was
     reviewed.  This proposal was not adopted.

   o Status of the ATM MIB

     Beyond the details mentioned earlier, no other open issues where
     identified.  It was decided unanimously to recommend this
     Internet-Draft to the area director for further processing by NMDIR
     and the IESG as a Proposed Standard after these details have been
     fixed on the mailing list.  The target is to wrap up before the end
     of the year (in accordance with the charter).

   o ATM Management Beyond the ATM MIB

     Some interest had been expressed to pursue management of switched
     virtual circuits (SVC). However, it was decided not to pursue this
     at this time.  Consequently, the working group can be inactivated
     after the ATM MIB and SONET MIB have been progressed as Proposed
     Standards.  The mailing list will remain active for the exchange of
     implementation experience or any other ATM/SONET management
     discussion.


Generic Connection Table

Ken Rodeman gave a presentation on a generic approach to the management
of virtual connections, suggesting a common approach for frame relay and
ATM. The generic approach would serve as an umbrella over connection
tables that are specific to frame relay or ATM. The contents of the
specific tables would not be affected by adoption of the generic
approach.  Rather, the specific approach would simplify the overall
management of connections.  Discussion of this topic was deferred to the
Interfaces MIB Working Group.
