+Abstract
+
+   This memo 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 (RMON) devices for use on high speed networks.  This
+   document contains a MIB Module that defines these new objects and
+   also contains definitions of some updated objects from the RMON-MIB
+   in RFC 2819 and the RMON2-MIB in RFC 2021.

+
+
+1.  The SNMP Management Framework
+
+   The SNMP Management Framework presently consists of five major
+   components:
+
+      o  An overall architecture, described in RFC 2571 [1].
+
+      o  Mechanisms for describing and naming objects and events for the
+         purpose of management.  The first version of this Structure of
+         Management Information (SMI) is called SMIv1 and described in
+         STD 16, RFC 1155 [2], STD 16, RFC 1212 [3], and RFC 1215 [4].
+         The second version, called SMIv2, is described in STD 58, RFC
+         2578 [5], RFC 2579 [6], and RFC 2580 [7].
+
+      o  Message protocols for transferring management information.  The
+         first version of the SNMP message protocol is called SNMPv1 and
+         is described in STD 15, RFC 1157 [8].  A second version of the
+         SNMP message protocol, which is not an Internet standards track
+         protocol, is called SNMPv2c and is described in RFC 1901 [9],
+         and RFC 1906 [10].  The third version of the message protocol
+         is called SNMPv3 and is described in RFC 1906 [10], RFC 2572
+         [11], and RFC 2574 [12].
+
+      o  Protocol operations for accessing management information.  The
+         first set of protocol operations and associated PDU formats is
+         described in STD 15, RFC 1157 [8].  A second set of protocol
+         operations and associated PDU formats is described in RFC 1905
+         [13].
+
+      o  A set of fundamental applications described in RFC 2573 [14]
+         and the view-based access control mechanism described in RFC
+         2575 [15].
+
+   A more detailed introduction to the current SNMP Management Framework
+   can be found in RFC 2570 [22].
+
+   Managed objects are accessed via a virtual information store, termed
+   the Management Information Base or MIB.  Objects in the MIB are
+   defined using the mechanisms defined in the SMI.
+
+   This memo specifies a MIB module that is compliant to the SMIv2.  A
+   MIB conforming to the SMIv1 can be produced through the appropriate
+   translations.  The resulting translated MIB must be semantically
+   equivalent, except where objects or events are omitted because no
+   translation is possible (use of Counter64).  Some machine readable
+   information in SMIv2 will be converted into textual descriptions in
+

+
+   SMIv1 during the translation process.  However, this loss of machine
+   readable information is not considered to change the semantics of the
+   MIB.
+
+2.  Overview
+
+   This document continues the architecture created in the RMON MIB [RFC
+   2819] by supporting high speed networks.
+
+   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, often geographically remote.
+
+   The objects defined in this document are intended 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.  These functions should be handled by the
+   management application.
+
+2.1  Structure of MIB
+
+   Except for the mediaIndependentTable, each of the tables in this MIB
+   adds high capacity capability to an associated table in the RMON-1
+   MIB or RMON-2 MIB.
+
+   The objects are arranged into the following groups:
+
+      - mediaIndependentGroup
+
+      - etherStatsHighCapacityGroup
+
+      - etherHistoryHighCapacityGroup
+
+      - hostHighCapacityGroup
+
+      - hostTopNHighCapacityGroup
+
+      - matrixHighCapacityGroup
+
+      - captureBufferHighCapacityGroup
+

+
+      - protocolDistributionHighCapacityGroup
+
+      - nlHostHighCapacityGroup
+
+      - nlMatrixHighCapacityGroup
+
+      - nlMatrixTopNHighCapacityGroup
+
+      - alHostHighCapacityGroup
+
+      - alMatrixHighCapacityGroup
+
+      - alMatrixTopNHighCapacityGroup
+
+      - usrHistoryHighCapacityGroup
+
+   These groups are the basic units of conformance.  If a remote
+   monitoring device implements a group, then it must implement all
+   objects in that group.  For example, a managed agent that implements
+   the network layer matrix group must implement the
+   nlMatrixSDHighCapacityTable and the nlMatrixDSHighCapacityTable.
+
+   Implementations of this MIB must also implement the system and
+   interfaces group of MIB-II [16,17].  MIB-II may also mandate the
+   implementation of additional groups.
+
+   These groups are defined to provide a means of assigning object
+   identifiers, and to provide a method for agent implementors to know
+   which objects they must implement.
+
+3.  Updates to RMON MIB and RMON2 MIB objects

+   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",

+
+   Good Packets
+
+   Good packets are error-free packets that have a valid frame length.
+   For example, on Ethernet, good packets are error-free packets that
+   are between 64 octets long and 1518 octets long.  They follow the
+   form defined in IEEE 802.3 section 3.2.all.  Implementors are urged
+   to consult the appropriate media-specific specifications.
+
+   Bad Packets
+
+   Bad packets are packets that have proper framing and are therefore
+   recognized as packets, but contain errors within the packet or have
+   an invalid length.  For example, on Ethernet, bad packets have a
+   valid preamble and SFD (Start of Frame Delimiter), but have a bad FCS
+   (Frame Check Sequence), or are either shorter than 64 octets or
+   longer than 1518 octets.  Implementors are urged to consult the
+   appropriate media-specific specifications.

+                        Pkts * (.96 + .64) + (Octets * .08)
+        Utilization = -------------------------------------
+                                Interval * 10,000
+
+        The result of this equation is the value Utilization
+        which is the percent utilization of the ethernet
+        segment on a scale of 0 to 100 percent.
+
+        This table is not appropriate for monitoring full-duplex
+        ethernets. If the network is a full-duplex ethernet and the
+        mediaIndependentTable is monitoring that network, the
+        utilization can be calculated as follows:
+
+        1) Determine the utilization of the inbound path by using
+           the appropriate equation (for ethernet or fast ethernet)
+           to determine the utilization, substituting
+           mediaIndependentInPkts for etherStatsHighCapacityPkts, and
+           mediaIndependentInOctets for etherStatsHighCapacityOctets.
+           Call the resulting utilization inUtilization.
+
+        2) Determine the utilization of the outbound path by using
+           the same equation to determine the utilization, substituting
+           mediaIndependentOutPkts for etherStatsHighCapacityPkts, and
+           mediaIndependentOutOctets for etherStatsHighCapacityOctets.
+           Call the resulting utilization outUtilization.
+
+        3) The utilization is the maximum of inUtilization and
+           outUtilization. This metric shows the amount of percentage
+           of bandwidth that is left before congestion will be
+           experienced on the link."

+6.  Security Considerations
+
+   In order to implement this MIB, a probe must capture all packets on
+   the locally-attached network, including packets between third
+   parties.  These packets are analyzed to collect network addresses,
+   protocol usage information, and conversation statistics.  Data of
+   this nature may be considered sensitive in some environments.  In
+   such environments the administrator may wish to restrict SNMP access
+   to the probe.
+
+   A probe implementing this MIB is likely to also implement RMON [RFC
+   2819], which includes functions for returning the contents of
+   captured packets, potentially including sensitive user data or
+   passwords.  It is recommended that SNMP access to these functions be
+   restricted.
+
+   There are a number of management objects defined in this MIB that
+   have a MAX-ACCESS clause of read-write and/or read-create.  Such
+   objects may be considered sensitive or vulnerable in some network
+   environments.  The support for SET operations in a non-secure
+   environment without proper protection can have a negative effect on
+   network operations.
+
+   SNMPv1 by itself is not a secure environment.  Even if the network
+   itself is secure (for example by using IPSec), even then, there is no
+   control as to who on the secure network is allowed to access and
+   GET/SET (read/change/create/delete) the objects in this MIB.
+
+   It is recommended that the implementers consider the security
+   features as provided by the SNMPv3 framework.  Specifically, the use
+   of the User-based Security Model RFC 2574 [RFC2574] and the View-
+   based Access Control Model RFC 2575 [RFC2575] is recommended.
+
+   It is then a customer/user responsibility to ensure that the SNMP
+   entity giving access to an instance of this MIB, is properly
+   configured to give access to the objects only to those principals
+   (users) that have legitimate rights to indeed GET or SET
+   (change/create/delete) them.
