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 RFC2819 and the RMON2-MIB in RFC2021.

1. The SNMP Management Framework
The SNMP Management Framework presently consists of five major
components:
o An overall architecture, described in RFC2571 [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, RFC1155 [2], STD 16, RFC1212 [3], and RFC1215 [4].
The second version, called SMIv2, is described in STD 58, RFC
2578 [5], RFC2579 [6], and RFC2580 [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, RFC1157 [8]. A second version of the
SNMP message protocol, which is not an Internet standards track
protocol, is called SNMPv2c and is described in RFC1901 [9],
and RFC1906 [10]. The third version of the message protocol
is called SNMPv3 and is described in RFC1906 [10], RFC2572
[11], and RFC2574 [12].
o Protocol operations for accessing management information. The
first set of protocol operations and associated PDU formats is
described in STD 15, RFC1157 [8]. A second set of protocol
operations and associated PDU formats is described in RFC1905
[13].
o A set of fundamental applications described in RFC2573 [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 RFC2570 [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].

DESCRIPTION
"The variable for each host that the hostTopNRate
variable is based upon, as well as a control
for the table that the results will be reported in.
This object may not be modified if the associated
hostTopNStatus object is equal to valid(1).
If this value is less than or equal to 7, when the report
is prepared, entries are created in the hostTopNTable
associated with this object.
If this value is greater than or equal to 8, when the report
is prepared, entries are created in the
hostTopNHighCapacityTable associated with this object."
::= { hostTopNControlEntry 3 }
From the RMON2 MIB:
nlMatrixTopNControlRateBase OBJECT-TYPE
SYNTAX INTEGER {
nlMatrixTopNPkts(1),
nlMatrixTopNOctets(2),
nlMatrixTopNHighCapacityPkts(3),
nlMatrixTopNHighCapacityOctets(4)
}
MAX-ACCESS read-create

DESCRIPTION
"The variable for each nlMatrix[SD/DS] entry that the
nlMatrixTopNEntries are sorted by, as well as a control
for the table that the results will be reported in.
This object may not be modified if the associated
nlMatrixTopNControlStatus object is equal to active(1).
If this value is less than or equal to 2, when the report
is prepared, entries are created in the nlMatrixTopNTable
associated with this object.
If this value is greater than or equal to 3, when the report
is prepared, entries are created in the
nlMatrixTopNHighCapacityTable associated with this object."
::= { nlMatrixTopNControlEntry 3 }
From the RMON2 MIB:
alMatrixTopNControlRateBase OBJECT-TYPE
SYNTAX INTEGER {
alMatrixTopNTerminalsPkts(1),
alMatrixTopNTerminalsOctets(2),
alMatrixTopNAllPkts(3),

alMatrixTopNEntries are sorted by, as well as the
selector of the view of the matrix table that will be
used, as well as a control for the table that the results
will be reported in.
The values alMatrixTopNTerminalsPkts,
alMatrixTopNTerminalsOctets,
alMatrixTopNTerminalsHighCapacityPkts, and
alMatrixTopNTerminalsHighCapacityOctets cause collection
only from protocols that have no child protocols that are
counted. The values alMatrixTopNAllPkts,
alMatrixTopNAllOctets, alMatrixTopNAllHighCapacityPkts, and
alMatrixTopNAllHighCapacityOctets cause collection from all
alMatrix entries.
This object may not be modified if the associated
alMatrixTopNControlStatus object is equal to active(1)."

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 RFC2119.
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.

SYNTAX OBJECT IDENTIFIER
MAX-ACCESS read-create
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 RFC1213 and RFC2233 [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.
This object may not be modified if the associated

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.

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."
