4.  The SNMP Management Framework

The SNMP Management Framework presently consists of five major
components:

    o   An overall architecture, described in RFC 2271 [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 RFC 1155 [2],
        RFC 1212 [3] and RFC 1215 [4]. The second version,
        called SMIv2, is described in RFC 1902 [5], RFC 1903
        [6] and RFC 1904 [7].

    o   Message protocols for transferring management
        information. The first version of the SNMP message
        protocol is called SNMPv1 and described in RFC 1157
        [8]. A second version of the SNMP message protocol,
        which is not an Internet standards track protocol, is
        called SNMPv2c and described in RFC 1901 [9] and RFC
        1906 [10]. The third version of the message protocol
        is called SNMPv3 and described in RFC 1906 [10], RFC
        2272 [11] and RFC 2274 [12].

    o   Protocol operations for accessing management
        information. The first set of protocol operations and
        associated PDU formats is described in 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
        2273 [14] and the view-based access control mechanism
        described in RFC 2275 [15].

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





Steven Waldbusser  Expires December 22, 1999          [Page 3]

Internet Draft  RMON for High Capacity Networks  June 22, 1999


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.

5.  Overview

This document continues the architecture created in the RMON
MIB [RFC 1757] 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.


5.1.  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






Steven Waldbusser  Expires December 22, 1999          [Page 5]

Internet Draft  RMON for High Capacity Networks  June 22, 1999


        - 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.

6.  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.

    STATUS current
    DESCRIPTION
        "This TC describes an object which counts events with the
        following semantics: objects of this type will be set to
        zero(0) on creation and will thereafter count appropriate
        events, wrapping back to zero(0) when the value 2^64 is
        reached.

        Provided that an application discovers the new object within
        the minimum time to wrap it can use the initial value as a
        delta since it last polled the table of which this object is
        part.  It is important for a management station to be aware of
        this minimum time and the actual time between polls, and to
        discard data if the actual time is too long or there is no
        defined minimum time.

        Counter32 and Counter64 values are read by subtracting the
        values of two polls retrieved at different times, resulting
        in a count of the number of events that occurred between
        the first poll and the second poll. There is no defined
        way to measure the number of events between the time the
        counter was created and the time of the first poll.
        Typically this TC is used in tables where entries are added
        and deleted frequently or tables that are not intended to
        be downloaded frequently (e.g., because of their size).
        In such tables, there may be a long time between the
        creation of the counter and the first possible poll and
        this may in fact constitute a large portion of the lifetime
        of the counter."

        Gauge has its maximum value whenever the information being modeled
        is greater or equal to that maximum value; if the information

        "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."

8.  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 1757], 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 2274 [RFC2274]
and the View-based Access Control Model RFC 2275 [RFC2275] 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.
