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:

• An overall architecture, described in RFC 2571 [1].
  
  
• 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].
  
  
• 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].
      
      
• 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. .
      
      
• 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:

hostTopNHCInOctets(10),
hostTopNHCOutOctets(11)
}
MAX-ACCESS read-create
STATUS current
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:

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:

DESCRIPTION

"The variable for each alMatrix[SD/DS] entry that the 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)."
::= { alMatrixTopNControlEntry 3 }

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.

This object may not be modified if the associated

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.
