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.

    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.

Regards, Benoit
