CURRENT_MEETING_REPORT_
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.
