Re: SNMP MIB for 10 Gb/s Ethernet

Hi Dan,

I guess I am to blame for this one. In outline, what I was saying, was that I
did not believe that the IEEE 802.3ae 10Gb/s Ethernet Task Force should try to
write an entire SNMP MIB as was done recently in the case of IEEE Std
802.3ad-2000 Link Aggregation. The reason I believe this is that I think that
the management required for 10Gb/s Ethernet is an extension to the existing
management, not, as was the case in Link Aggregation, an entirely new set of
management. I therefore believed that we should do what we have done in the past
(for example in the case of IEEE std 802.3z-1998 1Gb/s Ethernet) whereby 802.3
only extended the management behaviors provided in Clause 30 and the associated
SNMP MIB specifications are extended through the usual IETF processes. That is
what I was referring to when I said 'produced by the IETF as usual'.

As far as the IETF process is concerned I understood the following (apologies if
I am wrong). A SNMP MIB proposal would have to be written. This would be an
extension to your existing MIB, with the extensions tracking the 10Gb/s
additions. This would then be submitted to you as the Working Group chair with a
request to consider to adopt it. It is then up to you as the Working Group chair
to consider if you want to discuss it. If you do decide to discuss it, it will
then be discussed at the following IETF meeting.

Now clearly I did not intend that a MIB would be submitted to you 'cold' without
discussing it with you or your group and I intended to contact you. I however
wanted (possibly incorrectly) to make sure that we had an idea of what was being
proposed as far as 10Gb/s was concerned, particularly in the area of the WAN
PHY, and that we had an outline idea of these management additions before we
contacted you. Clearly now is an excellent time and I certainly agree that it
would be a good idea to establish some communication between the two groups. The
fact that you are attending next weeks Plenary meeting is a great opportunity
and I look forward to discussing this with you further.

Isolation' (URL:

Subject:  SNMP MIB for 10 Gb/s Ethernet

I am trying to do my reading preparation for the Plenary meeting next week.
Browsing through the (not-attended) last meetings materials I fell upon the
presentation made in July by David Law, Edward Turner and Howard Frazier
concerning 'IEEE 802.3ae 10 Gb/s Ethernet Management MIB baseline Proposal'.
In this presentation I see that it is proposed that 802.3ae does not include
an SNMP MIB in its deliverables. It also makes twice mention of 'SNMP MIBs
produced by IETF as usual'. As I am chairing the IETF Ethernet Interfaces
and Hub MIB Working Group, I would like to know whether this was approved as
the 802.3ae policy on MIB issues. If true it would probably be useful to
establish some communication between the two groups. I will be next week in
Tampa, and we can have some discussions about this.
