RE: Last Call: <draft-yourtchenko-cisco-ies-09.txt> (Cisco Specific Information Elements reused in IPFIX) to Informational RFC

["Adrian Farrel" <adrian@xxxxxxxxxxxx>]

Thanks Benoit, that is an important point and is really helpful.

 

So, do I read you right if I say that this document records some NetFlow v9 features and codepoints that were accidentally missed when RFC 3954 was written.

 

Or are these later modifications to NetFlow v9 (let's call it v9.x) that use the same code point range but were not actually part of v9?

 

The question might arise as to whether this document is supposed to update 3954.

 

Thanks,

Adrian

Let me reply to myself: I forgot an important point, which might be useful if people start discussing AD sponsoring of this document, without actually having read it.

Let me stress the first sentence of the Introduction section.

   The section 4 of [RFC7012] defines the IPFIX Information Elements in

   the range of 1-127 to be compatible with the NetFlow version 9

   fields, as specified in the "Cisco Systems NetFlow Services Export

   Version 9" [RFC3954]. 

So this draft is clearly linked to the work in IPFIX RFC 7012 (IPFIX information model) and must follow the RFC 7013 rules (Guidelines for Authors and Reviewers of IPFIX Information Elements), therefore would benefit from more reviews.

It's probably not too clear from the abstract, and should be improved.

OLD:

   This document describes some additional Information Elements of Cisco

   Systems, Inc. that are not listed in RFC3954

NEW:

   This document describes some additional IPFIX Information Elements in 

   the range of 1-127, which is the range compatible with field types used 

   by NetFlow version 9 in RFC3954, as specified in the IPFIX Information Model

   RFC 7012.

Adrian,

Not an answer to the process question, but some background information on this draft.
This draft, which is now 3 years old, has been evolving with the IPFIX standardization.
For example, looking at http://tools.ietf.org/rfcdiff?url2=draft-yourtchenko-cisco-ies-09.txt, you can see the interaction with the IPFIX WG document ietf-ipfix-data-link-layer-monitoring: now that
ietf-ipfix-data-link-layer-monitoring is in the RFC editor queue, the draft has been simplified, and some IPFIX Information Elements in the range 1-127 became deprecated.
This explains why the draft has been presented and reviewed multiple times in the IPFIX WG, and also why it would benefit from a wider review than the independent stream.

Regards, Benoit (as draft author)

Hi,

I have a process question on this last call which is not clear from the last
call text.

Are we being asked to consider whether publication of this document is useful,
or are we being asked for IETF consensus on the *content* of the document?

It seems from the document that the content is descriptive of something
implemented by a single vendor. I applaud putting that information into the
public domain, but I don't understand the meaning of IETF consensus with respect
to this document.

Thanks,
Adrian
