Abstract

   This document defines a portion of the Management Information Base
   (MIB) for use with network management protocols in TCP/IP-based
   internets.  In particular, it defines objects for managing remote
   network monitoring devices.

   This document obsoletes RFC 2021, updates RFC 3273, and contains a
   new version of the RMON2-MIB module.

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].

2.  Overview

   The RMON2 MIB defines objects that provide RMON analysis up to the
   application layer.

   Remote network monitoring devices, often called monitors or probes,
   are instruments that exist for the purpose of managing a network.
   Often, these remote probes are stand-alone devices and devote
   significant internal resources for the sole purpose of managing a
   network.  An organization may employ many of these devices, one per

   network segment, to manage its internet.  In addition, these devices
   may be used for a network management service provider to access a
   client network, which is often geographically remote.

   The objects defined in this document are intended to serve as an
   interface between an RMON agent and an RMON management application
   and are not intended for direct manipulation by humans.  While some
   users may tolerate the direct display of some of these objects, few
   will tolerate the complexity of manually manipulating objects to
   accomplish row creation.  The management application should handle
   these functions.

2.1.  Remote Network Management Goals

   o  Offline Operation

      There are times when a management station will not be in constant
      contact with its remote monitoring devices.  This sometimes occurs
      by design, in an attempt to lower communications costs (especially
