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> on behalf of Benoit Claise <benoit.claise=40huawei....@dmarc.ietf.org> Date: Monday, February 5, 2024 at 12:37 PM To: mohamed.boucad...@orange.com <mohamed.boucad...@orange.com>, Aitken, Paul <pait...@ciena.com>, Joe Clarke (jclarke) <jcla...@cisco.com>, opsawg@ietf.org <opsawg@ietf.org> Cc: t...@ietf.org <t...@ietf.org>, ts...@ietf.org <ts...@ietf.org>, 6...@ietf.org <6...@ietf.org>, ip...@ietf.org <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.

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.
