Re: Additional FC MIBs proposed

["Julian Satran" <Julian_Satran@il.ibm.com>]

Keith,

I do not recall the IPS working group
having a FC MIB in it's charter, nor having being asked to extend the charter
to include it by a popular vote or the IESG.

I do not know how the MIB draft got
to have the name draft-ietf-ips... that implies a working group work item
and I follow this group work from its inception.

David asked a question to which the
answer was silence or NO.  IPFC - or the designated trustees of it's
documents are the place to take this.

Subject	Re: Additional FC MIBs proposed

The issue with doing the MIBs in T11 is that T11 has,
in the past, not
had the appropriate amount of MIB expertise.  My understanding is
that
T11 themselves acknowledged this by the submission of the "Fibre
Alliance MIB" as draft-ietf-ipfc-fcmgmt-int-mib.  However, as
and when
the IPFC WG had completed all other items in its charter, it had been
unable to reach consensus on that MIB.  So, to allow the IPFC WG to
conclude, the unfinished work item was moved to the IP Storage WG.
After abortive attempts to get changes in draft-ietf-ipfc-fcmgmt-int-mib,
I created draft-ietf-ips-fcmgmt-mib as a MIB which: a) meets IETF's
standards, b) replaces both draft-ietf-ips-fcmgmt-mib and the overlapping
RFC 2837, and c) details the problems with those previous MIBs.

Meanwhile, T11 has published on its website a copy of one version (I'm
not sure if it's the latest version) of draft-ietf-ips-fcmgmt-mib.
Since that MIB is widely implemented in the industry, I agreed that
such publication would be appropriate *if* T11's publication indicated
that the MIB is already being deprecated by the IETF's definition of
draft-ietf-ips-fcmgmt-mib.  The last time I looked, T11 had failed
to
do that; rather, T11 seem to have published draft-ietf-ips-fcmgmt-mib
as if it were the definitive standard for a Fibre Channel MIB.
(However, the MIB was still in its Internet-Draft format, and perhaps
T11 intended that as an indication that the MIB was just a draft, as
ephemeral as all Internet-Drafts are, by definition).  These recent
actions of T11 suggest to me that they still do not have the
appropriate amount of MIB expertise.

The bottom line is that a bad MIB was widely implemented in the industry,
and I believe that network management of Fibre Channel devices suffered
because of that.  A better MIB for Fibre Channel has been defined
in the
IP Storage WG, who have already discussed the definition of further FC
MIBs
(see http://www.pdl.cmu.edu/mailinglists/ips/mail/msg09473.html), but
deferred them as future work.

Keith.
