CURRENT_MEETING_REPORT_ Reported by Keith McCloghrie/Hughes Minutes of IETF 802.3 Hub MIB Working Group (HUBMIB) The meeting was called to order at 4:00 by co-Chairs Donna McMaster and Keith McCloghrie. Agenda o Introduction o IEEE Report o Repeater MIB - Status - Implementation Experience o Repeater MAU MIB - Review of Instantiation Issues - Technical Walkthrough o Plans for Future 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. 2 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 3 status.
