                         Entity MIB (Version 4)

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 Simple
   Network Management Protocol (SNMP) agent.  This document specifies
   version 4 of the Entity MIB.  This memo obsoletes version 3 of the
   Entity MIB module published as RFC 4133.
