51st IETF Hubmib Working group London meeting minutes
Thursday 9 Aug, 2001

1.	Agenda by Dan 
2.	WIS MIB status by Dan –
	a.	Joint session held on Tuesday
	b.	Design team put in place from editors from both working 
		groups and drafts
	c.	Three major issues: 
		1) layer model and mapping into ifTable 
		2) mapping of the IEEE objects into the SNMP MIB objects
3) reconciliation of Ethernet-style and SONET-style counters
3.	IEEE 802.3 Status by Dan
	a.	One plenary and one interim meetings have happened since
last IETF
	b.	802.3ae on schedule (Last editing ends by Sep this year)
		i.	Last chance to provide input either via your
company 
			or via Dan through the IEEE voting process
		ii.	Standard expected to be done by March 2002
	c.	802.3af is late (more than one year!)
		i.	draft 2.0 9 2001
		ii.	will have an impact on our schedule
	d.	802.3ah (Ethernet For the First Mile) PAR approved
		i.	Includes EPON, Ethernet over VDSL and point to
point fiber
		ii.	Expect to take 2 years at IEEE
		iii.	Expect to take 1 year to come to IETF for MIB
definition
		iv.	Maybe a tutorial in the next IETF meeting based
on 
			the interest on the list
	e.	Request from IEEE 802.3 WG chair –
		i.	Cooperation between two organizations
		ii.	If any objects needed to be added, this working
group will 
			let IEEE know and to consider
		iii.	Questions raised regarding IETF – IEEE process 
			and Dan/Bert clarifies:
			1.	Use DAN to voice any technical issue to
expedite 
				the changes that might arise from this
working group
			2.	This has actually not happened before
		iv.	Questions raised regarding timing between two
groups 
			– chicken and egg problem
			1.	Change so that they consider to add them
to the 
				draft standard to “to their draft
standard”
		v.	The proposal for additional text in the Charter
will be 
			taken by Bert to the IESG for approval'
4.	Working Document Status by Dan
	a.	Power mib first draft out
	b.	Changes to the Ethernet interface/MAU mib draft 3 out
	c.	WIS mib first draft out
5.	Implementation report status by Yasha
	a.	Not present at the meeting (but sent a representative)
	b.	Yasha has not received any implementation experience 
		from the working group
	c.	Dan suggested sending Yasha’s email address again and 
		solicit for report from the mailing list
	d.	What are the issues and what is not implemented?
	e.	About 3 ½ vendors in the meeting can provide
implementation report
6.	Ethernet/MAU MIB status by John Flick
	a.	Added 64 bit counters – wrap up time is specified in the
DESCRIPTION (most of them can roll over within 5 minutes)
	b.	IfMtu – larger frame sizes not just IEEE 1500 – 
		call for clarification in the DESCRIPTION that this
frame 
		size is viewed from the network layer
	c.	802.3ad does provide ifStackTable mapping.  This needs
work 
		in the draft.
	d.	Open Issues for Ethernet MIB:
		i.	StretchRatio is read-writable in 802.3 draft.  
			This is for debug and detecting WIS interface.  
			(The latter is supported by other object
already).  
			– leave it open and take it to the list.  
		ii.	Which correct value for ifHighSpeed?
			1.	should be 9294 Mb/s since it is viewed
from 
				the PCS layer.
		iii.	Loopback test needs to be added to this MIB
since 
			ifTestTable is obsoleted
		iv.	IF-MIB packet/octet counter mappings – 
			1.	Outbound discards are counted twice
			2.	Inbound discards are counted once
			3.	PAUSE frame is counted in OCTETs but not
frames
			4.	Dan suggested posting the diagram (by
John) 
				to this working group as well as IEEE
and call 
				for clarification
	e.	Test table will be added to the Ethernet MIB not MAU MIB
	f.	Open Issues for MAU MIB:
		i.	The auto-configuration for speed, duplex and
pause 
			are too complex. Suggestion by John to use a
single 
			object that enum all the combinations.
		ii.	Dan agreed that if most people implemented the
MIB 
			this way then we should adopt the change and
deprecate 
			the old objects
	g.	Next draft is pending implementation report and WIS MIB
draft (2 months)
7.	Power Ethernet mib by Avi Berger
	a.	Deliver power over RJ45
	b.	For smaller device (no laptop yet!)
	c.	Question on how to provide PowerCDlassification object –
hardware detects the chip and power class defined in IEEE
	d.	In overCurrent condition, let go of the lower priority
line 
		and maintain the regular ones.  
	e.	LowPower and power saving concern - raise it to the
working group
	f.	IEEE will finish the draft by end of this month (1.3)
	g.	New IETF draft will be based on the new IEEE document
8.	802.17 new standard – do we do it in this working group?
	a.	A tutorial was presented in the iporpr WG
	b.	IPRPR claims it is not Ethernet
	c.	Hence it is not done in this working group
9. Close
