CURRENT_MEETING_REPORT_
Reported by Mark S. Lewis/Telebit
Minutes of the Modem Management BOF (MODEMMGT)
There were approximately 25 attendees made up of modem manufacturers,
SNMP developers, and modem users/service providers. The BOF was begun
with a discussion of the need to manage modems by users and service
providers. The Group explored the need to monitor and control modems,
as well as account for their usage. It was clear that the ability to
change the configuration of modems was important. It was suggested that
other devices like fax, DSU/CSUs, and perhaps terminal adapters should
be treated similarly. Most agreed that the Group should be as inclusive
as possible in writing a `modem' MIB.

MIB Hierarchy
Relevant MIBs including the RS-232-Like, Character, PPP, and DS1/E1
(RFC1406) were briefly discussed. Enterprise MIB extensions were
considered including those from Telebit and US Robotics. A short
presentation was made by Les Brown (TIA TR-30.4) on a Draft
Recommendation V.im; Management Information Model for V-Series DCE's.
It was noted that some vendors had looked at this Draft and had
implemented a subset of it. This may be the essential portion of what
seems to be a very comprehensive definition in the Draft.
Some raised issues about which problems the Group was trying to solve.
Others suggested that a clear statement about the problems would provide
helpful direction. Some questioned the model being considered: whether
it was geared for a stand-alone device or a rack installation. It was
agreed that a rack model should be used which supports multiple devices
through tables in a MIB rather than single objects.
There was a question about whether or not it was important to produce a
general modem MIB. It was suggested that some want extensive enterprise
MIB support from their particular vendor. Some of the SNMP management
station developers said they would not be willing to add support for
each vendors enterprise MIB extensions, but would be willing to add
support for a general modem MIB. It was agreed a general modem MIB was
necessary.
There was discussion about how many objects might be included in a modem
MIB. The V.im Draft seemed to define 200-250 objects. Some thought it
would be good to limit the modem MIB to around 100 objects. As a
comparison, the DS1/E1 MIB (RFC1406) defines approximately that many
objects.
Given the base of relevant work, the BOF Chair proposed that an IETF
working group be formed to work in conjunction with TR-30.4 to produce a
joint standard modem MIB. A proposed Charter was presented and
discussed. There was discussion about the different cultures of the two
Groups. There was some skepticism that the two Groups could produce a
joint document. The Chair proposed that discussions should be
carried-out through e-mail and periodic face-to-face meetings.
A proposed schedule was discussed which set certain goals. Basically,
the joint document would be completed in 1993. This means that the
joint Group would produce at least two drafts, which would be reviewed
face-to-face at least twice. Presumably, there would be extensive
e-mail discussion in the interim. Most considered this an aggressive
schedule but thought it was a good objective.
The BOF concluded with agreement that an IETF working group should be
organized to pursue these goals. The Chair agreed to update the
proposed Charter and submit it to the acting Management Area Director.
He also agreed to setup the required mailing list, and ftp repository of
relevant MIBs and documents.
