Description of Working Group:
The Ethernet Interfaces and Hub MIB WG is Chartered to define a set of managed objects that instrument devices, MAUs and interfaces that conform to the IEEE 802.3 standard for Ethernet. This set of objects should be largely compliant with, and even draw from IEEE 802.3, although there is no requirement that any specific object be present or absent.

Close coordination with hardware standards development in IEEE 802.3 will be followed. The WG chair will support the communication with IEEE 802.3. When objects are added that require hardware support, IEEE 802.3 shall be informed, so that they consider to add them to their draft/standard.

The MIB object definitions produced will be for use by SNMP and will be adequately consistent with other SNMP objects, standards and conventions.

The WG will define new MIB objects to cover the following 802.3 technologies:

P802.3ae - 10 Gb/s Ethernet

P802.3af - DTE Power via MDI

Goals and Milestones:
Done   Meet at the 41st IETF to discuss implementation experience of RFC 2108 and RFC 2239, and to consider future extensions for Full Duplex operation and 1 Gigabit Ethernet Speeds
Done   Gather implementation experience feedback concerning RFC 2108 and RFC 2239
Done   Post Internet-Draft(s) for Full Duplex and 1 Gigabit Ethernet MIB extensions
Done   Meet at the 42nd IETF to discuss the Internet-Draft(s) and issue recomendations concerning advancement of RFC 2108 and RFC 2239 on the standards track
Done   Post revised Internet-Draft(s)
Done   Conduct WG Last Call on Internet-Draft(s)
Done   Submit final version of the Internet-Draft(s) to the IESG for consideration as Proposed Standards
Done   Submit revised version of the Internet-Drafts, following the Area Directorate review
Done   Submit final versions of the MAU MIB and Ethernet-like Interfaces MIB Internet-Draft(s) to the IESG for consideration as Proposed Standards
Done   Submit the Ethernet Chipsets document to IESG for consideration as an Informational RFC
Done   Begin identifying new work items for future work
Done   Issue WG Drafts for MIBs for P802.3ae & P802.3af
Done   Issue revised WG Drafts for MIBs for P802.3ae/P802.3af
Dec 01   Gather implementation experience concerning WG documents already on the standards track
Jan 02   Issue revised WG drafts for existing stds track documents if so required by the implementation reports
Jan 02   Forward Internet-Drafts to the AD/IESG Stds track considerations
Jan 02   WG Last Call All documents

Minutes taken by Randy Presuhn -

There were no major changes to the proposed agenda for the joint atommib / hubmib meeting.

There was a update on the IEEE 802.3ae activity. Problems had been identified in the conformance clauses, and a new internal letter is planned. Draft 4.1 is in ballot, and draft 4.2 is hoped for by March 18, with an IEEE interim planned in

April and completion targeted for June, 2002. Fortunately, all major management-related comments have already been resolved.

The status report on the WIS (WAN Interface Sublayer)

MIB presented at the IEEE 803.2ae interim meeting indicated that the IEEE liked it, and that there was no contention surrounding the resolution of issues.

Recent changes include the addition of a new test pattern type, changing some flags to enumerations, and trace object alignment.

The editors of the WIS MIB are aware of a few edits that will be needed, and the plan is to wait for the 4.2 update from the IEEE, do a sanity check between the MIB and the GDMO definitions, then issue a working group last call on a document with an annex identifying known problems.

The document forwarded to the IESG will need to be "clean".

The WG last call will be done in the hubmib WG, but will also be announced on the atommib WG mailing list.

A review of RFC 2558 implementations from five different vendors showed that, when taken together, every object was supported by at least two implementations. The plan is to recommend the document for advancement from Proposed to Draft Standard.

The final discussion concluded that those present did not see a need for another joint meeting.
