Margaret, thanks for your note. Bert, see attached message from Margaret. the original thread is attached as well. as you know on this issue there were three issues raised: 1. document title is too vague 2. opaque object is cumbersome to implement 3. acceptance as work item on (1): seems resolvable to all satisfaction on (2): there has been some back&forth on this one; Juergen and Dave P thought that a URN approach may work best; Dave P. will provide a strawman (due to him being sick last week this has been delayed). on (3): Margaret refers to you given the state of the entmib WG. all I can add is that there have been a handful of expressions of support, and no objections (comments have focused on (1) and (2) instead). your guidance on how to carry this forward is appreciated, kaj X-Sender: [email protected] Date: Sat, 1 May 2004 11:09:45 -0400 To: Kaj Tesink <[email protected]>, [email protected] From: Margaret Wasserman <[email protected]> Subject: RE: [Entmib] Re: Entity mib support for tcif X-RAVMilter-Version: 8.4.2(snapshot 20021217) (thumper) X-Virus-Scanned: by AMaViS - amavis-milter ( http://www.amavis.org/ ) Hi Kaj, I'm sorry that I didn't answer this message sooner. I was on vacation in mid-April, and I'm only catching up now. 3. acceptance as work item since the original proposal i've seen several supporting comments but i leave this to the WG chair and AD to gauge The Entity MIB WG charter does not currently include this work, so we could not accept this document as a work item without a charter update. There are at least two concerns about updating the Entity MIB WG charter to include this item: 1) The WG has not been timely in completing our current work. 2) I was appointed to the IESG last July, and it is not considered a good idea for IESG members to run WGs. I stayed on as entmib WG chair because we were expected to complete our work within a few months (not that things have gone exactly as planned...). If the life of the WG will be extended by new work items, it will be necessary for Bert to identify and appoint a new chair. So, if you want to pursue this work in the IETF, you should talk to Bert Wijnen about the best way to do that. In the meantime, the only chartered work items for the entmib WG are completing the Entity State MIB and getting the Entity MIB promoted to Draft Standard.

Any chance of getting this done? i think the following issues have been raised: 1. document title is too vague 2. opaque object is cumbersome to implement 3. acceptance as work item 1. document title is too vague: current proposed title is: Definitions of Supplemental Entity Managed Objects the current contents of the MIB module is only two objects - manufacturing date - additional info (an opaque object with one currently identified application) i proposed this title to be a) in line with similar documentation techniques in the past b) to be compatible with possible extensions in the future given the two current objects, and that one of them is opaque, it is hard to be very specific. Dan suggested something like: 'Entity MIB Extensions for manufacturing date and physical module identification' or perhaps: Extensions to entPhysicalTable of the Entity MIB (more precise but still not very illuminating) I suggest we go with Dan's proposal. 2. opaque object is cumbersome to implement. the suggested construct was based on neat suggestions by Dave and was meant to accommodate several concerns and also allow flexibility. but several comments pointed out that this may be too cumbersome to implement. i attach the original proposal which was an object dedicated to CLEI. note that my original question was posed in the context of extending the Entity MIB directly instead of creating a separate document. any strong feelings against going back to the original? Dave? 3. acceptance as work item since the original proposal i've seen several supporting comments but i leave this to the WG chair and AD to gauge kaj ---snip from initial posting------------------------------------------------- ============================================================= new objects: entPhysicalCLIECode OBJECT-TYPE SYNTAX SnmpAdminString (SIZE (0..10)) MAX-ACCESS read-write STATUS current DESCRIPTION "The CLIE Code for the physical entity.

Have we decided whether the working group wants to take this on? i think that question is still pending; we asked for input and expressions of interest well before the last ietf meeting but there has not been much traffic on this since that request. so let me repeat the request for input on this spec: http://www.ietf.org/internet-drafts/draft-tesink-entity-supplmib-00.txt This is a requirement I've heard bounced around a few times so I think this is worth trying to address, but like Dan I have a few concerns with some aspects of the proposed solution. As he has mentioned, the title is not sufficiently descriptive. In addition, I think the data types might be too opaque to be useful. as per my comments based on Dan's note, there were some good reasons for the high level title, but i'd be open to other suggestions. as for the opaque object, the history is that the initial proposal based on an octet string syntax invoked a discussion about flexibility and some other aspects, and resulted in a proposal by Dave for the current opaque construct, although some other comments expressed reservations (i believe by Juergen and Dan). i'm willing to go with whatever the rough consensus dictates. kaj Sharon -----Original Message----- From: Kaj Tesink [ mailto:[email protected] ] Sent: Wednesday, February 11, 2004 10:25 AM To: [email protected] Subject: RE: [Entmib] Re: Entity mib support for tcif Hi Dan, At 10:03 PM 2/10/2004 +0200, Romascanu, Dan (Dan) wrote: >Kaj, > >I was among the ones who supported doing this work.

While this would more accurately reflect the content, there is the issue of future compatibility. The problem with adding new objects to MIBs over time is that a) either you add to the original spec; but this means there's a problem with advancing the spec over time b) or you define supplemental specs; the problem here is that you dont want all sorts of miblets around; you want to minimize the number So, similar as what we did for ATM, and attempted for DS1s, the tactic was to use this generic title, so that additional functions could still be added for a while. I agree its not perfect. I also thought that in previous discussions there were some thoughts about some additional functions(?). >2. Some of the concerns expressed in the meeting (not by me) were >related >to the availability and the proprietary nature of the CLEI codes. Can you >comment on these? Are the documents mentioned in the REFERENCE clause of >the cleiCode object freely available? You're right, some of that did come up before. My understanding is the following: - the references point to documents by different standards groups, and i think are available for a small fee at www.atis.org - CLEI codes are defined in those standards; Telcordia is the registrar to obtain an actual code In previous discussion it was pointed out that while CLEIs are in wide use, there is no obligation to use them; I've tried to reflect that in the draft in two ways: (a) use an opaque object instead of a dedicated object as proposed by Dave, and (b) language for the case that the whole thing (no CLEI nor any other application of the object) is not supported.
