Minutes of the Chassis MIB Working Group (CHASSIS)

The Group reviewed and approved the Agenda.  The current draft document
is dated January 27, 1993.

Revised Model for the Chassis MIB

Dave Arneson presented a revised model for the Chassis MIB. It consists
of three kinds of things within a chassis - modules, resources, and
entities.  Each resource is used to build up a single module;
independently each resource is used to build up a single entity.  The
first relationship is used to describe the physical location of a
resource.  The second relationship is used to describe the logical
functional unit for management access.

There are three primary tables in the model:


  1. A module table indexed by location type and slot number.
  2. A resource table indexed by loc-type, slot-#, and resource-#.
  3. An entity table indexed by entity number.


There was some discussion that the resource table should be two logical
tables:  one indexed by module information, and the other indexed by
entity information.  There was general consensus that the model is an
improvement, and reasonably general.

There was a discussion of whether we are modeling chassis configuration
or network topology.  The general consensus seemed to be that network
topology is a general problem and is not part of our requirement.

A remaining question was what access information is necessary for v1 and
v2.

Implementation Experience

Rick Royston discussed implementation experience.  He was concerned that
indexing was difficult, but thought that the new model would help.  He
was also concerned about keeping the management application informed
when the chassis configuration changed.  Finally, there was concern
about dynamic rules for what card is allowed to go in which slots.
