CURRENT_MEETING_REPORT_ Reported by Theodore Brunner/Bellcore Minutes of the Interfaces MIB Working Group (IFMIB) The group's discussions were based on the ``Evolution of the Interfaces Group of MIB-II'' Internet-Draft. The version dated 1 June was discussed first, followed by discussion of additional issues in the 28 June version. The discussion was a continuation of issues raised on the mailing list. Although only one session had originally been scheduled for IFMIB, a second session was scheduled ad hoc. The only other group from the Network Management Area whose schedule conflicted with the second session was UPSMIB. The group did not have time to discuss issues such as a generic approach to virtual connections. However, this particular subject was also expected to be addressed at the meetings for the FRNETMIB and ATOMMIB Working Groups. Discussion Topics: 1. ifNumber, ifName (section 3.2.1) Resolution: Current text is OK. 2. ifStack, ifTable concerns (section 3.2.2) Resolution: ifStack is OK. Interface specific MIBs should clarify how ifTable is used. I-D language will be drafted by editors. 3. Virtual Circuits (section 3.2.3) Resolution: Caralyn Brown will suggest a less controversial example. Not considered possible to add further text to clarify the circumstances under which a virtual circuit may be considered an interface. 4. linkUpDownEnable (in section 5.) Resolution: Confirmed that the default layer generating linkUp and linkDown is the lowest layer. 5. Do we want to deprecate objects in ifTable (in section 5) Resolution: Yes, want to consider candidates. Objects Resolution - ifType, ifSpecific Unresolved. A possible replacement will be discussed on the mailing list (by draft editors.) - ifPhysAddr change to macAddress Keep as is. - ifNUCast Discussion deferred. - ifOutQLen No general agreement that this object is useful. Proposal will be made on the mailing list (by Fred Baker and Jon Saperia.) 6. 64 bit Counters There was a suggestion to have two conformance classes for ease of management stations. Resolution: Tentative agreement to have 3 conformance classes: a) <20Mbps (32 bit Counters) b) >20Mbps (64 bit character Counters) c) >650Mbps (64 bit packet Counters) Because of 1 hour wrapping time of counters, and ease of agent. Resolution: No 64bit error counters. 7. ifHighSpeed (section 3.2.6) Resolution: Accepted 8. Support of ifExtns (from RFC1229) There has been some modest implementation of RFC 1229 expressed by two members of the WG. Ted Brunner will poll the ietf mailing list for any other implementation experience with it. Agreement was reached about the objects in Sections 8.1-8.3, but these agreements will be verified on the mailing list. Ted Brunner will send out the appropriate messages pointing out the level of agreement on these issues, and poll the mailing list for any dissagreements. 8.1. ifExtnsTable Resolution: ifExtnsRevWare, ifExtnsChipSet are deleted. ifExtnsPromiscuous is kept. Place it into the packet compliance group, and move its oid into the ifTable, and remove Extns from its new name. 8.2. ifExtnsTestTable Resolution: Will be kept as optional. Interface-specific MIBs may define tests that use this table, in which case an appropriate conformance statement is included in that MIB. Community, RequestId and COntext will be replaced with a testAndIncrement. The objects will be given new names (without Extns.) 8.3. ifExtnsAddrTable Resolution: Will be kept as optional. Interface-specific MIBs should define whether and how this table should be used, in which case an appropriate conformance statement is included in that MIB. 9. prototype or proposed Resolution: this mib will not be considered for prototype status, only for proposed. Other mibs depend on it.
