- MINUTES OF SESSION
- ------------------
-
- 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. We 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 we should be as
- inclusive as possible in writing a 'modem' MIB.

- MIB Hierarchy
-
- We briefly discussed relevant MIBs including the RS-232-Like,
- Character, PPP, and DS1/E1 (RFC 1406). Enterprise MIB extensions were
- briefly 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 pointed out 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 issue about which problems we are trying to solve. Others
- suggested a clear statement about the problems would provide helpful
- direction. Some questioned the model being considered: whether is was
- geared for a stand-alone device or a rack installation. It was agreed
- that we should use a rack model 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 object 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 (RFC 1406) 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 2 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.
