Dan,

This new IEEE standard was published on July 1, 2011.  Since it 
includes updated versions of the MIB modules defined in RFC 2108, 
RFC 3621, RFC 3635, RFC 3637, RFC 4836, RFC 4837, RFC 4878, and RFC 
5066, a question arises: would it be appropriate for the meta-data 
for these RFCs to indicate that they are obsoleted by IEEE Std 
802.3.1?

Not sure if the RFC-editor can do or normally doies this. Dan, do you know.

If not, I guess we could write 1-2 page RFC that obsoletes the listed RFCs with a
pointer to the IEEE document.

Hi, 

I am not sure, I need to consult with the IESG, as the issue of a
non-IETF document obsoleting an IETF document may be rather new. I see
that we did not make such a note on RFC 4188, when work was transferred
to the IEEE 802.1WG. I am copying DBH who wrote RFC 4663. 

To be clear - we are talking only about the meta-data for these RFCs,
not about changing their status to Historic (for which the procedure is
described by an IESG statement -
http://www.ietf.org/iesg/statement/designating-rfcs-as-historic.html) 

Thanks and Regards,

Dan

Hello Dan,

Indeed, my question was just about changing the meta-data.  The 
reason for doing so would be to encourage implementors to migrate 
from the IETF versions of these MIB modules, which are no longer 
being maintained, to the IEEE versions of the MIB modules, which 
will be maintained in the future.

Since the IEEE has re-rooted their versions of the modules under new 
top-level OIDs, the existing IETF MIB modules will still need to be 
supported in order to manage the installed base of devices.  To me 
that souds like a good reason NOT to move them to Historic status.

Thanks and regards,

Mike Heard

Well, my proposal then would be that we write a 1-2 page informational RFC that
explains that the new IEEE modules are the newer modules and should be used.
The new RFC that we write then obsoletes the IETF MIB RFCs. So they
do not become historic, but they get obsoleted bij an informational
(or BCP if that is better) RFC document that explains why and points to
the new current IEEE MIB modules.

Hi Bert, 

I thought that we can avoid the writing of such an RFC for the
transition of the Ethernet MIB documents to IEEE 802.3, as we already
approved the transition process within the IESG, and the IEEE 802.3 have
completed the first phase of the work. Would you or somebody else object
to having the IESG approve marking the IETF RFCs as 'obsolete' and
pointing to the IEEE 802.3 in the meta-data or you do believe that we
must have this information in an RFC and run this through a consensus
process which is broader than the IESG? 

Thanks and Regards,

If you can do it that way, then that would be fine with me.
It would be less work (supposedly).

Dan,

We did not discuss this option for the 802.1 MIBs at the time, even though that was the general intent.  

The view was that if someone wanted to implement a simple bridge, they could use the IETF MIBs (in RFC 4188, 4318 & 4363).

As a result we imported some definitions from the IETF BRIDGE-MIB and Q-BRIDGE-MIB instead of redefining them.

Given this, is making the IETF Bridge MIBs obsolete appropriate?

For 802.3, I don't think there are any imports from the IETF MIBS, so this would be cleaner.

Cheers,
Glenn.

Thanks for reminding one important reason for not making the IETF Bridge

There is no intention to change this, at least AFAIK.

Hi,

As I recall, when we did the transfer, it was agreed that the IETF
Bridge MIBs would continue to be standards (i.e. not be obsolete or
historic), and the defined compliance levels would continue to be
valid for those who wished to comply only to the IETF standards.

IEEE had an interest in extending the IETF MIB modules in ways that
were not backwards compatible, such as totally modifying indexes to
existing tables in order to support per-provider(?) discriminators.
IETF Bridge MIBs have been widlet deployed in enterprise environments,
and many of those environments had no desire to move to the
per-provider approach that was/is important to service providers.

Allowing the continuation of the IETF compliance as a valid option
addressed this difference in perspective.

I suppose one could draw a parallel with the RADIUS/Diameter split and
co-existence for different environments.

Greetings,

David Harrington and Glenn Parsons both provide good reasons why the 
status of the IETF Bridge MIB modules should remain unchanged.

My question, however, concerned the Ethernet-related MIB modules in 
RFCs 2108, 3621, 3635, 3637, 4836, 4837, 4878, and 5066.  The 
situation for those is different.  New versions (rooted under 
different OIDs) have been published in IEEE Std 802.3.1, and the 
overview section of that document says that it "supersedes and makes 
obsolete" those RFCs.

Hi Mike, 

I think that everybody who expressed opinions in this thread agreed with
your suggestion to mark the said RFCs as Obsoleted by IEEE 802.3.1 ...
We also seem to agree that if possible we would do it by an IESG
decision, avoiding the extra cost of writing an RFC. I am not sure yet
that the IESG will accept this proposal, and I hesitate to run it in the
busy week before the IETF meeting. 

Question - do we need to run this beyond the hubmib list? A one-slide
presentation in the OPSAREA meeting for example?

Hi, 

I think that the situation with the Ethernet MIB modules is somehow
different from the one with the Bridge modules on this respect. The
Ethernet MIB modules laready covered some of the SP space when Ethernet
started to propagate in the Metro and WAN applications. There is no
clear separation and what IEEE 802.3 continues the work in the IETF.
Actually the first set of MIB modules issued by IEEE 802.3.1 changes
little in the MIB modules structure beyond moving their root under IEEE
control and extending the range of supported PHYs and MAUs. 

I may not know all that is happening and I am ready to stand corrected
if I am missing information. As I am at the IEEE 802 meeting this week I
will try to learn more on the IEEE 802.3 side. 

Regards,

Dan

Dan,

Waiting until after the IETF meeting to run the proposal past the 
IESG sounds quite reasonable.

If the IESG is open to the proposal, it seems to me that a 
widely-announced IETF last-call should suffice.  My suggestion would 
be to cc: the last call announcement to the hubmib, ietfmibs, 
ops-area, and (possibly) opsawg lists (besides of course 
ietf-announce, where all such things appear).

Thanks

Mike

Hi Mike, 

Hmmmm ... 'a widely announced IETF last call' implies writing an I-D,
and probably making it an RFC. What would be last-calling? Do you think
that we need an official last-call? I thought that for modifying the
meta-data information for the RFCs an IESG decision would be enough.
Wound a less official question asked on the lists beyond be sufficient?
Frankly, if we go all the way and we write an I-D and make it an RFC (we
also need a volunteer for this) I would rather go all the way and make
the RFCs Historic. 

I spoke with Howard Frazier (who is chairing the IEEE 802.3.1 effort)
today. As expected he agrees with the proposal. The second phase of the
MIB revision in IEEE 802.3 is already chartered and with the exception
of the repeater and copper EFM MIB modules all the other MIB modules
will go through changes.

Dan,

Sorry, my bad -- I did not mean to suggest anything heavyweight, 
certainly not publishing an RFC, just giving adequte notice to 
interested parties of the intended action.  Something less official 
than a last call put to the relevant lists would be quite 
sufficient.

Thanks and regards,

Mike

P.S.  I'll be out of e-mail contact for approximately the next 10 
days; I'll try to be prompt about attending to anything in the queue 
when I return.
