Abstract

   This memo defines a portion of the Management Information Base (MIB),
   the Aggregation MIB modules, for use with network management
   protocols in the Internet community.  In particular, the Aggregation
   MIB modules will be used to configure a network management agent to
   aggregate the values of a user-specified set of Managed Object
   instances and to service queries related to the aggregated Managed
   Object instances.

1.  The Internet-Standard Management Framework

   For a detailed overview of the documents that describe the current
   Internet-Standard Management Framework, please refer to section 7 of
   RFC 3410 [RFC3410].

   Managed objects are accessed via a virtual information store, termed
   the Management Information Base or MIB.  MIB objects are generally
   accessed through the Simple Network Management Protocol (SNMP).

   Objects in the MIB are defined using the mechanisms defined in the
   Structure of Management Information (SMI).  This memo specifies a MIB
   module that is compliant to the SMIv2, which is described in STD 58,
   RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580
   [RFC2580].

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in BCP 14, RFC 2119
   [RFC2119].

2.  Background

   For the purpose of management, it is necessary to access Managed
   Objects (MOs).  The SNMP framework provides a mechanism for naming
   and describing managed objects.  These objects are accessed via a
   virtual information store termed a Management Information Base (MIB).
   MIBs have been defined by equipment, protocol, and application
   developers to provide management access to the managed entities.  We
   will call the MOs defined in these MIBs simple MOs (SMO).  Management
   applications will access one or more instances of these SMOs, one or
   more times, to monitor the target entity.

   There is a cost associated with accessing MOs.  The cost is the
   network bandwidth and the packet header processing overhead at the
