Abstract

   This memo defines a portion of the Management Information Base (MIB)
   for use with network management protocols in the Internet community.
   In particular, it describes managed objects used for managing
   multiple logical and physical entities managed by a single SNMP
   agent.  This document specifies version 3 of the Entity MIB, which
   obsoletes version 2 (RFC 2737).
