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

   This document extends the enumerations in the following objects from
   the RMON MIB [18] and the RMON2 MIB [20].

From the RMON MIB:

hostTopNRateBase OBJECT-TYPE

4.  Conventions

   The following conventions are used throughout the RMON MIB and its
   companion documents.

   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 RFC 2119.

   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.

    DESCRIPTION
        "This object identifies the source of the data that
        this mediaIndependent entry is configured to analyze.  This
        source can be any interface on this device.
        In order to identify a particular interface, this
        object shall identify the instance of the ifIndex
        object, defined in RFC 1213 and RFC 2233 [16,17], for
        the desired interface.  For example, if an entry
        were to receive data from interface #1, this object
        would be set to ifIndex.1.

        The statistics in this group reflect all packets
        on the local network segment attached to the
        identified interface.

        An agent may or may not be able to tell if
        fundamental changes to the media of the interface
        have occurred and necessitate a deletion of
        this entry.  For example, a hot-pluggable ethernet
        card could be pulled out and replaced by a

        token-ring card.  In such a case, if the agent has
        such knowledge of the change, it is recommended that
        it delete this entry.

    DESCRIPTION
       "The total number of frames which were received by the probe
        and therefore not accounted for in the
        mediaIndependentDropEvents, but for which the probe chose not
        to count for this entry for whatever reason.  Most often, this
        event occurs when the probe is out of some resources and
        decides to shed load from this collection.

        This count does not include packets that were not counted
        because they had MAC-layer errors.

        Note that, unlike the dropEvents counter, this number is the
        exact number of frames dropped."

    DESCRIPTION
        "The total number of octets of data (including
        those in bad packets) received on the
        network (excluding framing bits but including
        FCS octets).

        If the network is half-duplex Fast Ethernet, this
        object can be used as a reasonable estimate of
        utilization. If greater precision is desired, the
        etherStatsHighCapacityPkts and
        etherStatsHighCapacityOctets objects should be sampled
        before and after a common interval.  The differences
        in the sampled values are Pkts and Octets,
        respectively, and the number of seconds in the
        interval is Interval.  These values
        are used to calculate the Utilization as follows:

                        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.
