Hi all, Bob is right here.
However, the intent of the original text is unambiguous as per the following: == Description This Information Element describes the forwarding status of the flow and any attached reasons. The reduced-size encoding rules as per [RFC7011] apply. The basic encoding is 8 bits. The future extensions could add one or three bytes. Abstract Data Type: unsigned32 == Unless an extension is defined, unsigned8 will be used anyway following the reduced-encoding in 7011.

Cisco doesn’t have any specific change control over it. Agreed, but they (Cisco) have to say whether this is an error or not, not the community. I would put it differently. Anyone can report an errata, the Area Directors make the decision if the errata is accepted. That may including checking with the authors. They do not check with the company where the authors worked at the time the RFC was published. Bob Regards, Benoit If there are known errors in it, they should be reported in an Errata. The ADs who approve errata will take the correct action.

What is key is the Cisco internal document that contains the Cisco IPFIX registry. So when I wrote " I don't feel comfortable having an errata on a Cisco-specific IPFIX", I actually meant: " I don't feel comfortable having an errata on a Cisco-specific IPFIX without Cisco approving this". Regards, Benoit On 2/5/2024 7:12 PM, Andrew Feren wrote: Hi Benoit, I see your point about not having an errata on a Cisco RFC. That being said…. It appears that the IANA page has listed forwardingStatus(89) as unsigned8 since 2018. Also CCO-NF9FMT<http://www.cisco.com/en/US/technologies/tk648/tk362/technologies_white_paper09186a00800a3db9.html>, the other cisco document referenced for forwardingStatus(89), is pretty unambiguous that forwardingStatus(89) is 1 byte. Beyond that I don’t have strong feelings about this. The different int sizes never seemed all that useful to me anyway since mostly it is the size sent in the template that matters. -Andrew From: IPFIX <ipfix-boun...@ietf.org><mailto:ipfix-boun...@ietf.org> on behalf of Benoit Claise <benoit.claise=40huawei....@dmarc.ietf.org><mailto:benoit.claise=40huawei....@dmarc.ietf.org> Date: Monday, February 5, 2024 at 12:37 PM To: mohamed.boucad...@orange.com<mailto:mohamed.boucad...@orange.com> <mohamed.boucad...@orange.com><mailto:mohamed.boucad...@orange.com>, Aitken, Paul <pait...@ciena.com><mailto:pait...@ciena.com>, Joe Clarke (jclarke) <jcla...@cisco.com><mailto:jcla...@cisco.com>, opsawg@ietf.org<mailto:opsawg@ietf.org> <opsawg@ietf.org><mailto:opsawg@ietf.org> Cc: t...@ietf.org<mailto:t...@ietf.org> <t...@ietf.org><mailto:t...@ietf.org>, ts...@ietf.org<mailto:ts...@ietf.org> <ts...@ietf.org><mailto:ts...@ietf.org>, 6...@ietf.org<mailto:6...@ietf.org> <6...@ietf.org><mailto:6...@ietf.org>, ip...@ietf.org<mailto:ip...@ietf.org> <ip...@ietf.org><mailto:ip...@ietf.org> Subject: Re: [IPFIX] errata eid7775 RE: [**EXTERNAL**] RE: WG LC: IPFIX documents [EXTERNAL] CAUTION: This email originated from outside of the organization.

Hi Paul, On 1/23/2024 12:14 PM, mohamed.boucad...@orange.com<mailto:mohamed.boucad...@orange.com> wrote: 4.3. forwardingStatus In particular, the registered Abstract Data Type is unsigned8, while it must be unsigned32. Why must it be? [Med] As per the definition in RFC7270. I've opened an errata for that: https://www.rfc-editor.org/errata/eid7775 [Med] I don’ think an erratum applies here because the intent of 7270 is clearly unsigned32: While you and I were working on NetFlow at Cisco when we wrote the RFC 7270, I don't feel comfortable having an errata on a Cisco-specific IPFIX. Anyway, what is the issue with keeping unsigned32, should we be liberal in what we accept? And we know that the reduced-size encoding (https://datatracker.ietf.org/doc/html/rfc7011.html#section-6.2) will be used anyway. It's not even useful to have this sentence (" IPFIX reduced-size encoding is used as required") in the description but I can live with it.
