- Reported by Brian D. Handspicker/DEC
-
-
- MINUTES
-
- The November 2, 1989 meeting of Netman/CMOT WG was opened by co-chair
- Brian Handspicker. Lou Steinberg was appointed recording secretary for
- this meeting.
-
-
- 1. NEW GROUP NAME
-
- The group has changed its name to better reflect its charter to
- "OSI INTERNET MANAGEMENT". The charter will be clarified to
- reflect our goals to specify management of IP-based and OSI-based
- local area and wide area networks in the Internet. The management
- recommendations specified by this group will be based on OSI
- management standards and working drafts, NIST implementors
- agreements and Network Management Forum recommendations.
- For the most part, this group is not defining new standards, but
- rather is recommending how existing OSI specifications and
- implementors agreements can be used for the management of the
- Internet.
-
- 2. NEW DOCUMENTS
-
- To follow through on this charter, five documents will be generated
- and circulated by the end of 1989:
-
- o Implementors Agreements
- o Event Management
- o SMI Extensions
- o MIB Extensions
- o OSI Management Overview
- o Guidelines for the Definition of Internet Managed Objects
-
- These documents will all have the super-title: OSI Management for
- the Internet. These documents will be circulated as Internet
- Drafts with the intention that prototypes of each these agreements
- will be completed and tested before each is proposed as an Internet
- RFC. It is hoped that this testing can be completed by March/April
- 1990.
- Throughout the creation and testing of these drafts the OIM WG will
- attempt to maintain close alignment with the Alert-Man and
- Management Services Interface WGs.
-
- (a) Implementors Agreements
-
- The implementors agreements will specify protocol, SMI and MIB
- agreements. The protocol agreements will reference the new IS
- version of ISO CMIP. The IS CMIP is expected to be registered
- in early 1990. Experts have estimated that it will take about
- 3 man-weeks to align a DIS-based CMIP implementation with the
- IS draft. This was considered to be insignificant compared to
- the value of providing initial CMOT products based on the IS.
- In addition, the protocol agreements will be drafted to specify
- both CMIP Over lpp over Tcp (CMOT) and CMIP over full OSI stack
- (CMIP). In either case, the Application Layer protocol is
- identical. The SMI agreements will reference the Internet
- extended SMI. The MIB agreements will reference the Internet
- extended MIB-II.
- There is the potential for future work on a version of CMIP
- that runs on top of full ISO Session and Presentation on top of
- TCP instead of LPP. This may provide improved interoperability
- between CMOT and CMIP implementations. This may not be
- necessary if dual stack systems become popular. This issue
- will not be addressed in the current documents.
- The implementation examples in the appendix of the current CMOT
- document will be retained in the new Implementors Agreements.
-
- (b) Event Management
-
- An Event Management Model has been proposed which aligns with
- current OSI Event Management and Reporting. Some concern was
- expressed that the OIM Event Management Model align with the
- work being done within the Alert-Man WG. In addition there is
- an opportunity to align SNMP traps and OIM events codes and
- semantics.
-
- (c) SMI
-
- The SMI Extensions document will reference the current Internet
- SMI and then specify extensions as necessary to support OSI
- Management of the Internet. In addition, the SMI document will
- reference the current ISO version of SMI in an attempt to align
- with ISO.
-
- (d) MIB
-
- Tentatively, the MIB extensions document will reference the
- current Internet MIB-II specification. We currently do not
- know of anything in MIB-II that causes problems to CMOT. This
- should be carefully reviewed by OSI experts. In addition, this
- MIB document will define extensions necessary to align with OSI
- Management. These extensions will include:
- DistinguishedAttributes for MIB-II "objects" and events. There
- is some concern that MIB-II should not include an in-line
- version no. in the variable codes. We were assured that the
- in-line version no. was not defined in MIB-II. The full MIB-II
- and all extensions defined in this document will be mapped into
- the ISO Template language.
- After this MIB document, protocol groups are not expected to
- define new MIBs or MIB extensions. It is expected that as new
- objects are defined by other working groups (e.g. OSI) the
- management information associated with those objects will be
- specified by the WG that defines the new object.
-
- (e) OSI Mangement Overview
-
- The Overview sectionand the Examples appendix of the current
- CMOT document will be retained in a new Overview document.
-
- (f) Guidelines for the Definition of Internet Managed Objects The
- IETF wrapup (closing plenary) participants recommended that the
- management groups write guidelines for defining managed
- objects. This will help the non-management groups (e.g. OSI)
- define the managed objects associated with their services.
- This document is not the same as the ISO GDMO draft. This
- document is specific to the IETF and may point to other
- document (such as GDMO) as additional reading.
-
-
- 3. INTEROPERABILITY TESTING
-
- There is vendor interest in availability of an interoperability
- testing lab. DEC is willing to set up and run such a lab in the
- next few months. They are currently looking for facilities on the
- West Coast. Vendors interested in participating in such a lab
- should contact Dave Crocker.
- HP will solicit comments on desired test cases and produce a
- document specifying test scripts.
- HP has offered to host the next OIM meeting focusing on
- interoperability. This meeting will likely be in January in the
- Bay Area.
