Description of Working Group:
Fibre Channel is a high speed network technology primarily used for storage networking (i.e., Storage Area Networks [SANs]). Two important aspects of Fibre Channel interact with the Internet: - Fibre Channel can encapsulate and carry IP protocol traffic - Fibre Channel devices can be managed via SNMP

The Internet and Management Support for Storage WG (imss) is chartered to address two areas, specifically: - IPv4 over Fibre Channel has been specified in RFC 2625. A corresponding specification for IPv6 is needed. - An initial Fibre Channel Management MIB has been developed by the IP Storage (ips) WG; extensions are needed to encompass management of additional aspects of Fibre Channel, such as zoning.

In the future, other storage related MIBs for other storage transports such as INCITS T10 Serial Attached SCSI (SAS) or SCSI command specific MIBs may be proposed. This group would work with the appropriate technical committee(s) in a manner similar to that described for INCITS T11 below.

As Fibre Channel standardization is handled by the INCITS T11 Technical Committee (http://www.t11.org), a close working relationship with T11 is essential to the WG's success. In particular: - The IPv6 over Fibre Channel specification will be based on draft-desanti-ipv6-over-fibre-channel-02.txt. This draft was originally developed within a T11 study group and T11 has officially recommended this draft to the IETF. - The WG will not standardize management of Fibre Channel features ahead of their incorporation into appropriate T11 Fibre Channel standards. - The WG will work closely with T11, specifically Task Group T11.5, on the functionality and structure of the MIBs it develops for management of Fibre Channel.

In addition to working closely with the INCITS T11 Technical Committee, this Working Group will work closely with IETF IPv6 Working Group as appropriate. In particular, the IPv6 Working Group will be kept informed on the progress and status of the IPv6 over Fibre Channel specification. The IMSS Working Group Last Call announcement will be cross-posted to the IPv6 WG mailing list.

Goals and Milestones:
Done  Submit IPv6 over Fibre Channel draft to IESG for consideration as Proposed Standard
Aug 04  Work with T11.5 to determine what additional MIB modules are needed
Oct 04  Submit Fibre Channel Domain Manager MIB to IESG for consideration as Proposed Standard
Oct 04  Submit Fibre Channel Name Server MIB to IESG for consideration as Proposed Standard
Jan 05  Submit Extensions for Fibre Channel Interfaces MIB to IESG for consideration as Proposed Standard
Jan 05  Review working group charter and determine what additional work, if any, should be undertaken by working group
No Current Internet-Drafts

Current Meeting Report

IMSS WG Minutes

Meeting held on August 2, 2004, 7:30 pm

This was the second meeting of the IMSS.

Status of the working group presented by Elizabeth Rodriguez (IETF60IMSS.ppt)
After reviewing the agenda and 'Note Well', the relationship between IETF IMSS WG and INCITS T11 was discussed.
* In particular, T11 is the technical committee that develops FC standards, but does not have MIB experties. Therefore, MIB development is a joint effort between T11 and IETF, where T11 insures the FC techical correctness while utilizing the MIB expertise of the IETF.
* The cooperative effort between IMSS WG and the T11.5 task group is discussed, covering how the documents are handled and handed off between the groups.

Next, the milestones were discussed. In summary:
* The first WG draft has been published as an RFC: RFC 3831, IPv6 over Fibre Channel
* No other work in the hands of the IMSS working group currently. Expectation that the first draft to be forwarded by T11, the Fabric Address Manager (FAM) MIB, would be appoved the week of August 2. The second, the Name Server (NSM) MIB, expected to be forwarded to IMSS before next IETF meeting.
* The Fibre Channel Interfaces MIB is on hold, pending determination if it will be needed.
* T11 has identified two other MIBs that should be developed and will begin work on those MIBs shortly.

Next, Elizabeth Rodriguez presented the status of the FAM and NSM MIBs on behalf of Keith McCloghrie. ( kzm-imss-status-aug04.ppt)

* The Domain Manager MIB has been renamed as the Fabric Address Manager MIB. This is the same MIB and the draft is still bears the old name, draft-desanti-fc-domain-manager-02.txt. The content of the MIB was covered, along with its status in T11: The draft had undergone a T11 letter ballot (the letter ballot is the process by which T11 the draft for techical content and determines it is ready to be forwarded on to IMSS), with a vote of Y38-N02-A12 (38 companies voted yes, 2 no and 12 abstained). Comments from the letter ballot were resolved. Pending final approval.
* The Name Server MIB internet draft is available as draft-desanti-fc-name-server-02.txt. The content of the MIB was covered, along wiht its status in T11. It also had a letter ballot issued, with the same results. Letter ballot comment resolution in process.

Finally, Roger Cummings, T11.5 liaison, covered status from T11.5's perspective. (imss_tg5status200408.ppt)
* Descriptions of INCITS and the INCITS storage Techical Committees, in particular T11.
* Discussed the "Cooperative Stragegy between T11.5 and IMSS.
* Reference provided for anyone who wishes to see details of the letter ballot on the Fabric Address Manager and Name Server MIBs.
* Both MIBs targeted to be submitted as WG drafts by the November IETF.
* T11 has appoved two new MIBs to be developed:Routing Information MIB (called SM-RTM) and Fibre Shortest Path First (FSPF, called SM-FSM), with a target is to ask IMSS to adopt as a working group item in March 2005 (by IETF-62.

This concluded the scheduled material. No one had any points for discusson when open mike announced, so the meeting concluded.
