IP Over Fibre Channel BOF (FIBREIP)
Reported by Yakov Rekhter/IBM Corporation
Overview of the ``IP and ARP on Fibre Channel'' Internet-Draft
Yakov Rekhter presented the overview of the Internet-Draft. A copy of
the presentation follows these minutes.
SSESCO Implementation
Status of the SSESCO implementation (based on information provided by
Craig W. Carlson from SSESCO) was presented by Yakov.
o Uses the SNAP/LLC header as outlined in the Internet-Draft.
o Uses broadcast ARP. The Ancor switch allows small packets (less
than 128 bytes) to be broadcast. The driver uses this ability to
broadcast ARP packets in the same way that ethernet does. The
format of the ARP packets follows what was specified in the
Internet-Draft.
o A mixture of message classes is used. For packets greater than 128
bytes, Class 1 is used. For packets less than or equal to 128
bytes, Class 3 is used. (This is actually user selectable, but the
default is to use Class 3 for small packets.)
o The driver is able to talk to the HP driver (except for ARP) that
also uses the SNAP/LLC headers outlined in the Internet-Draft. It
has not yet been tested against the IBM adapter since IBM uses
Fibre Channel version 4.2 while Ancor is still using version 3.0.
Ancor is in the process of going to 4.2 so there will be some data
in the near future.
o This is currently running on two platforms. The IBM RS/6000 using
the Ancor Micro Channel Adapter, and the SGI Indigo2 using the
Ancor EISA adapter.
Implementation by IBM
The status of the IBM implementation (information from Dan Eisenhauer)
was presented by Yakov. A copy of the presentation follows these
minutes.
Future Activities
Advancing Internet-Draft to a Proposed Standard:
o The group agreed that the document should be advanced to a Proposed
Standard as soon as SSESCO, IBM and HP implementations are tested
for interoperability. Ken Hays (Florida State University) agreed
to lead the interoperability test effort.
MIB for Fibre Channel:
o The group agreed to publish the N_Port MIB Internet-Draft as an
Informational RFC once there is at least one implementation of this
MIB. The document will be updated to make it SMIv2 conformant.
Discussion on the need to develop and standardize the Fabric MIB
did not reach any conclusion.
Working Group and Mailing List:
o The group agreed that there is no need to form an IETF working
group or establish a separate mailing list.
