                        Exporting MIB Variables
         Using the IP Flow Information Export (IPFIX) Protocol

Abstract

   This document specifies a way to complement IP Flow Information
   Export (IPFIX) Data Records with Management Information Base (MIB)
   objects, avoiding the need to define new IPFIX Information Elements
   for existing MIB objects that are already fully specified.

   Two IPFIX Options Templates, as well as a method for creating IPFIX
   Options Templates that are used to export the extra data required to
   fully describe Simple Network Management Protocol (SNMP) MIB objects
   in IPFIX, are specified herein.
