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

Waldbusser Standards Track [Page 2] RFC 3273 Remote Network Monitoring Management July 2002

 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:
  1. mediaIndependentGroup
  1. etherStatsHighCapacityGroup
  1. etherHistoryHighCapacityGroup
  1. hostHighCapacityGroup
  1. hostTopNHighCapacityGroup
  1. matrixHighCapacityGroup
  1. captureBufferHighCapacityGroup

Waldbusser Standards Track [Page 3] RFC 3273 Remote Network Monitoring Management July 2002

  1. protocolDistributionHighCapacityGroup
  1. nlHostHighCapacityGroup
  1. nlMatrixHighCapacityGroup
  1. nlMatrixTopNHighCapacityGroup
  1. alHostHighCapacityGroup
  1. alMatrixHighCapacityGroup
  1. alMatrixTopNHighCapacityGroup
  1. 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].

      alMatrixTopNTerminalsOctets,
      alMatrixTopNTerminalsHighCapacityPkts, and
      alMatrixTopNTerminalsHighCapacityOctets cause collection

4. Conventions

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

Waldbusser Standards Track [Page 6] RFC 3273 Remote Network Monitoring Management July 2002

 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.

  STATUS     current
  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

      card could be pulled out and replaced by a

Waldbusser Standards Track [Page 10] RFC 3273 Remote Network Monitoring Management July 2002

  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:

Waldbusser Standards Track [Page 19] RFC 3273 Remote Network Monitoring Management July 2002

                      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.
