Re: [IPFIX] review of draft-ietf-ipfix-mib-variable-export-07

Thanks for this Juergen. I'll produce an updated version for the editorial issues.

For the BITS issue, the largest IPFIX types are currently 64 bits (ie, signed64 / unsigned64). Although we could request a 128-bit type, we're simply moving the absolute limit along without solving the underlying issue.

Do you know what size the largest BITS object is today? Would it be acceptable to limit the size that can be exported in IPFIX to the first 64 or 128 bits?

Thanks,
P.
