CURRENT_MEETING_REPORT_ Reported by Bob Stewart/Xyplex 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. Actions Group members Apply the model to their own devices and 1 report back.
