- Reported by Barbara Sterling/McDATA
-
- Minutes of the SNA Systems Management BOF (SNAMIB)
-
- The meeting opened with an introduction of all attendees. A roster, as
- well as an Interest Grid, was circulated. Baktha Muralidharan went over
- the Agenda which was then passed without dissent. The criteria for
- forming a working group for a MIB were discussed. Basically at least
- three or more people (one Chair, one author, one editor) who are willing
- to participate actively are needed before a working group can be formed.
- In addition, a working group's charter preferably should include
- milestone dates.
-
- A poll was taken to show interests in the various areas of SNA. The
- following is the result.
-
- PU 2.0: 5
-
- PU 2.1: 7
-
- PU 4: 1
-
- PU 5: 1
-
- APPN (End Node and Network Node): 2
-
- APPC: <a lot>
-
- SDLC: 5
-
- LLC-2: 4
-
- QLLC: 1
-
- Channel-attached: 3
-
- Data Link Switching: 4
-
- APPI: 1
-
-
-
- Note: This poll only reflects the interests of the attendees. It was
- pointed out that for some areas, such as APPI, there may be other
- vendors who are interested but not present.
-
- The following issues were brought up during the meeting:
-
- 1
-
-
-
-
-
- o How well will the MIBs reflect the client's point of view?
-
- o The relationship between SNMP and NetView:
-
- - How do the two relate to each other: does it mean sending SNMP
- information to NetView?
- - What is the scope of management by each protocol?
-
- o Splitting the host management aspect from PU 5. Some felt that
- there are wider interests in managing SNA topology network than SNA
- hosts.
-
- o Placement of related areas into one or separate MIBs. For example,
- should APPN End Node be a separate MIB from the APPN Network Node?
- Should PU 2.1 belong to the APPN MIB (since it describes LEN) or to
- the PU MIBs (with PU 2.0)? It was decided to defer detailed MIB
- organization discussion until later.
-
-
- Marshall Rose pointed out the differences between proprietary and
- standard MIBs. A standard MIB should never contain vendor-specific
- details but should be a core set of information common to all. In
- addition, a standard MIB loses meaning if it is not widely adopted and
- implemented by the community.
-
- Session Two
-
- The meeting was opened by Baktha, who recapped session one. Baktha
- proposed a working group structure composed of four distinct working
- groups, based upon the discussions of session one:
-
-
- WG1: PUT2.0, PUT2.1, APPN End Node, APPN Network Node, APPI
- WG2: SDLC, LLC-2, Channel, QLLC
- WG3: APPC, LUs
- WG4: Data Link Switching (DLSw)
-
-
- A series of discussions ensued, involving:
-
-
- o The number of working groups needed or desired -- issues included:
-
- - There is a need for overall architectural control to ensure all
- MIBs complement each other.
- - Considerable overlap of participation is expected if there are
- multiple working groups.
-
- 2
-
-
-
-
-
- - How to minimize the size and number of mailing lists, including
- having one mailing list even if multiple working groups are
- formed.
- - To ensure communication between multiple working groups, each
- working group would have other working groups review and
- sign-off documents prior to publishing them.
- - Relevance of number of vendors/users present at BOF versus
- other interested vendors/users in determining priority of
- certain MIB structures.
- - Moving DLSw to WG2.
- - Moving PUT2.0 to WG3.
- - LUs topic should include LU types 0,1,2,3,4,6.2,7
-
-
- o IBM indicated that, in approximately one month, it intends to
- submit its current APPN MIB as a Draft Standard in order to aid
- network management vendors in preparing to support IBM's APPN
- functions for the 6611 router. Discussion followed, including:
-
- - Is there a real need to propose this MIB as a standard now,
- assuming a working group is to be formed that addresses this
- issue?
- - Should the APPN MIB be published as an informational draft
- instead?
- - The IESG and/or IAB is likely to not accept IBM's submission as
- a Draft Standard and will refer the matter to the established
- working group.
- - IBM also has an APPC MIB that they plan to submit to the IETF
- in the future.
-
-
- o The Group developed consensus in these areas:
-
- - There will be two working groups:
- * WG1 -- Logical SNA Protocols (includes PUT2.0, PUT2.1, APPN
- EN, APPN NN, APPI, APPC, all LUs).
- * WG2 -- Data Link Layer (includes SDLC, LLC-2, Channel, QLLC,
- DLSw). The Charter of the group will be to examine the
- issues relating to and publish the MIBs required to enable
- management of logical SNA protocols and their data link
- layers by SNMP, defining capabilities that are similar to
- those provided to IBM's NetView (R) network management
- product.
-
-
- o Milestones for this Group include:
-
- 3
-
-
-
-
-
- - The working groups will publish a draft document to the mailing
- list identifying how many MIBs are to be defined within the
- scope of this effort. This draft will be published within two
- months of the formation of the working groups.
- - During July 1993, first drafts of the MIBs will be reviewed by
- the mailing list.
- - The working groups will meet at the July 1993 IETF meeting.
- - One mailing list will be defined that will include both working
- groups.
-
-
- A suggestion was made that the Chair post a ``request for
- participation'' for these working groups to the IETF mailing list,
- encouraging both vendors and users to participate.
-
- Discussions relating to staffing the two working groups were deferred to
- BOF Session Three.
-
- Session Three
-
- It was decided to make the Charters more specific and focused than had
- previously been decided. Proposed WG1 will work on MIBs for PUs 2 and
- 2.1 and LUs 1,2 and 3. Proposed WG2 will work on MIBs for SDLC and
- LLC-2 data link protocols. The Charters for these first two groups are
- not meant to preclude the creation of future working groups to develop
- ``SNA MIBs'' in other areas of common interest.
-
- It was mentioned that the MIB for LLC-2 will need to be coordinated with
- the similar IEEE MIB definition effort.
-
- Several individuals volunteered to edit and/or author the documents and
- other volunteered to chair the working groups.
-
- o Bill Kelly. Editor Working Group 1 (PU2, PU2.1 and LUs 1,2,3)
-
- o Shannon Nix and Wayne Clark. Editors Working Group 2 (LLC-2 and
- SDLC)
-
- o Baktha Muralidharan, Jeff Hilgeman and Zbigniew Kielczewski.
- Chairs (Area Director to make choices).
-
- o Baktha Muralidharan, Zbigniew Kielczewski, Bill Kwan and Kitty
- Shih. Authors. PUs 2.0/2.1
-
- o Kitty Shih and Zbigniew Kielczewski. LUs
-
-
-
- 4
-
-
-
-
-
- o Shannon Nix, Patrick Leung, Bill Kwan, and Rina Nathaniel. SDLC
-
- o Shannon Nix, Patrick Leung, and Wayne Clark. LLC-2
-
-
- Action Items
-
-
- o Baktha Muralidharan and Deirdre Kostick are to work on appropriate
- wording of the charters and distribute drafts to the mailing list.
-
- o Authors are to post their MIBs for WG's 1 and 2 by April 30th.
