-
- Minutes of the Uninterruptible Power Supply BOF (UPSMIB)
-
- Agenda
-
-
- o To identify the scope of the problem of monitoring and controlling
- uninterruptible power supplies;
-
- o To discuss an Internet Draft containing an initial proposal for
- such a MIB, and
-
- o To assess the interest and commitment towards ongoing work,
- including the possibility of creating a Working Group to prepare
- and advance proposals for standardization in this area. If there
- is sufficient interest and commitment, the Working Group Charter
- and timetable will be discussed.
-
-
- For this meeting, Jeff Case presided and Bob Stewart recorded. The
- meeting was well-attended, about 30 people, with representatives of
- about 10 UPS vendors, many becoming involved in the Internet and the
- IETF for the first time. After considerable discussion and review of a
- proposal, the meeting decided to request startup of a Working Group,
- with most of the work being done via a mailing list.
-
- Goal
-
- Efforts to make uninterruptible power supplies to be monitorable and
- controllable via the Internet Standard Management Framework have already
- begun. In the past, when MIB standardization has trailed product
- development, as it did for terminal servers, intelligent repeaters, and
- MAC bridges, users have been faced with the difficulties associated with
- the unnecessary proliferation of similar, but different,
- enterprise-specific (vendor) MIBs. As a result, it is desirable to
- begin standardization efforts as soon as possible.
-
- A draft document has been prepared as an introduction to the problem.
- It states:
-
-
-
- This memo defines an experimental portion of the Management
- Information Base (MIB) for use with network management
- protocols in TCP/IP-based internets. In particular, it defines
- objects for managing uninterruptible power supply (UPS)
- systems.

-
-
-
- The document which is in the Internet-Drafts Directory, as previously
- announced, is a new version of the memo which contains incorporates the
- suggestions received by the authors since the initial document was
- published, plus one new group, the upsTruck group.
-
- Jeff presented the organizations and procedures that oversee Internet
- Standard Development.
-
-
- o Mailing list discussion a bit of a problem due to lack of mail
- access by UPS vendors.
- o Stressed structure above IAB, current and changing.
- o All-volunteer lower structure.
-
-
- Jeff stated goals.
-
-
- o Decide whether to proceed.
-
- o Identify sufficiently interesting set of common attributes with no
- optional objects. The answer to a concern over response to
- unimplemented objects was that groups are the unit of conformance
- for interoperability.
-
-
- Jeff presented highlights of the strawman proposal, which caused several
- points of discussion.
-
-
- o Volts and Minutes are too coarse, tenths of volts and seconds
- better.
-
- o Concern over debating individual objects deferred for later
- detailed assessment of proposal.
-
- o Traps are to bin in a separate document to ease passage of MIB.
-
- o A UPS need not perform multiple tests simultaneously but may if it
- can.
-
- o It is implementation specific whether configuration options cause
- changes.
-
- o SNMP proxy mechanism preferred for handling multiple UPSes, rather
- than table with index.
-
- o A community string or party defines an agent.
-
- o Fielded systems are basic and advanced, MIB represents advanced,
- suggest organizing MIB accordingly. Agreed too much mandatory for
- less expensive devices. Agree with option by Group for predictable

- functions. This is a marketing issue. This discussion should be
- deferred for formal Working Group. We all want one standard.
-
-
- We discussed whether we do indeed want to form a Working Group.
-
-
- o Charter 1 or 2 documents to monitor and possibly control UPS, low
- or high end, existing and future UPS technology.
-
- o Consider application to similar embedded systems such as power
- systems or power conditioners.
-
- o Prefer not to encumber UPS needs.
-
- o There was considerable concern about voting and influence. Process
- is by consensus without company dominance or simple votes. The
- major need is to define the problem and rally around a Standard.
- SNMP itself was such a compromise.
-
- o We need an editor and email communication. MCI, Sprint,
- Compuserve, etc., provide mail service, and some do not charge for
- reading mail.
-
- o Arbitration is informal, by consensus and compromise.
-
- o Credit is author's on front and sometimes individuals in
- acknowledgements section, with name and affiliation.
-
- o Mail is easier than news group.
-
- o Publicity is acceptable as long as not claiming standard before
- complete. Internet Drafts should not be referenced in procurement
- or product literature, but RFCs may.
-
- o Mailing list administrative address is upsmib-request@cs.utk.edu.
-
- o We plan to have a document by the next IETF, final by following.
- The next IETF conflicts with Comdex, a big problem. Suggested Las
- Vegas meeting that vendors attend is a problem for Chairs.
-
-
- One of the vendors (APC) presented an alternative proposal.
-
-
- o MIB being implemented but needs to consider strawman proposal.
-
- o Proprietary features were removed for presentation. Remainder was
- divided into basic and advanced to maximize compatibility with past
- and future systems.

-
-
-
-
-
- o Extension objects point to further MIB, assuming it is similarly
- structure. A single object is preferred and sufficient.
-
-
- Several general issues were discussed before adjournment at 10:20.
-
-
- o Someone suggested a breaker group. That varies considerable across
- implementations. It could be handled by alarm group in strawman.
-
- o We looked at several objects in strawman and general consensus was
- they are implementable.
-
- o Although one of the proposers, Emerson, does not implement
- everything in the strawman, it was proposed for value to the
- industry.
-
- o On the issue of credit for draft and RFC the suggestion was to
- limit it to SNMP Research. Suggested that Emerson receive
- consideration as catalyst. Deferred to private discussions and
- mailing list.
-
- o Suggested September meeting central in U.S. deferred to mailing
- list.
