            Exporting MIB Variables using the IPFIX Protocol
                draft-ietf-ipfix-mib-variable-export-05

Abstract

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

   An IPFIX Option Template and method are specified, which are used to
   export the extra information required to fully describe Simple
   Network Management Protocol (SNMP) MIB Objects.
