My understanding from https://datatracker.ietf.org/doc/html/rfc7011#section= -6.1.1 is MUST be encoded using the default canonical format in network byte order Looking at https://www.rfc-editor.org/rfc/rfc7133.html#section-5.2 as examp= le, which is the same case, a 3-bit value in a unsigned8 data type, I would= expect that it would be encoded in network byte order (big-endian). So I tend to remove "The values are encoded in the first 3 bits of the IE" = since it is redundant or if required replace with "The values are encoded i= n the first 3 bits of the IE as defined in section 6.1.1 of RFC 7011". What= do you think? Regarding the registry. In the CCAMP interim Scott mentioned to clarify thi= s with with ITU-T and you wrote that you have asked IANA for their advice. = Did you get any response? I would expect that either Scott clarifies himself or gives me a pointer to= whom to follow up which is my job as author. Or perhaps IANA already knows= how to deal with ITU-T registries which would make it even easier.

Thomas, I agree that it's good to avoid duplicate registries. The IE definition could point directly to the corresponding ITU definitions= . Even better, we could create a new IPFIX sub-registry which points to the= ITU definition. In either case the definition should clearly say whether it's intended to o= nly use the ITU definition at the the time of publication, or to follow all= future updates. eg, if one of the Reserved values is defined in future. This could be the first time for such an IPFIX definition (where the full d= etails are external to the registry), so I've asked IANA for their advice. P.
