RMON and RMON2 Overview

RMON and RMON2 are MIB standards develop ed to provide powerful remo te troubleshooting and monitoring within a LAN segment and across an enterprise network. This chapter includes the following inf ormation:

T opic Page

RMON MIB

RMON MIB RMON2 MIB 1-3 RMON and RMON2 Support on Bay Networks Routers 1-8 RMON and RMON2 Architecture 1-9

RMON is a standard MIB that defines current and histor ical statistics and control objects at th e media acce ss cont rol (MAC) layer, allo win g you to ca pture r eal-ti me information across the enti re network. The RMON standard is an SNMP MIB definit ion described in RFC 1757 (formerly 1271) for Ethernet .

The RMON MIB provides a standard method for monitor ing the basic operations of the Ethernet network, providing interopera bility between Simple Network Management (SNMP) management stati ons and monitor ing agents. RMON also provides a powe rful alarm and eve nt mechanism for setting thresholds and for notifying you of changes in network behavior.

You can use RMON to analyze and monitor network traffic data within remote LAN segments from a central location, enabling you to detect, isolate , diagnose, and report potential and actual ne twork problems before they escalate to crisis situations. For example, the Ethernet DCM can identify the hosts on a network that generate the most traffic or errors.

Configuring RMON and RMON2

RMON allows you to set up automatic histories, which the RMON agent collects over a period of ti me, pr oviding trending data on such basic statistics as utilization , coll isions, a nd so f orth. Using a netw ork manage ment appli cati on such as Optivity LAN network usage patte rns . Bec ause RMON automates this data collection and provides b etter data to the pla nning process, the process is easier and the outcome more accurate.

Bay Networks implements se v en RMON MIB groups in its RMON agent, and the alarm and ev ent groups in its base module for BayStack AN/ANH and ARN routers. Table 1-1 about the RMON MIB groups, see Appendix C, “

RMON2 MIB

RMON2 is a standard MIB that extends the scope of the RMON MIB beyond the MAC layer to pro vide statistics on network and applic ation layer traffic (layers 3 through 7 of the OSI model). By monitoring higher-layer protocols, you can get an internetwork or enterprise-wide view of network traffic, enabling you to:

• Identify whic h systems are communicating with which serv ers a nd what

• Identify whic h devices are sending and receiving which types of traffic.

Using this knowl edge of traffi c patterns, you can strateg ic ally place users and resources in the correct loc ation on the network to optimize performance and reduce costs.

Figure 1-1 shows the level of vi sibility that RMON and RMON2 provide within a

LAN segment and within a network at each layer of the OSI model.

RMON and RMON2 Overview

With RMON2, you can also trouble shoot network problems faster and more accurately using statistics from the network layer matrix table, which shows the protocol-specific traffic between communicating pairs of systems.

For example, with RMON, you can learn that a particular server is inactive because it fails to transm it packets. W ith RMON2, you can diagnose the more diff icult problem that occurs when the syste m is active but a particular protocol stack is malfunctioni ng.

RMON2 provides address translation capabilities tha t bind MAC-layer addresses to network-layer addresses, making all addresses easier to read a nd remember. You can detect duplicate addresses, whic h help s to solve a common problem that disrupts network r outers and virtual LANs.

RMON2 allows you to collect the hist orical data of any counter in the system, rather than only a predef ined set of statistics. For example, you can collect historical da ta on a specific file server or a specific router-to-router connection.

RMON2 also lets you configure more flexible and efficient filters to support higher-layer protocols.

303539-A Rev 00

Bay Networks implements seven RMON2 MIB groups in its RMON2 agent for BayStack AN/ANH and ARN routers. Table 1-2

summarizes the RMON2 MIB groups. For more detailed information about the RMON2 MIB groups, see

RMON and RMON2 Architecture

The Bay Networks RMON and RMON2 ar chitecture consists of the fol lowing components:

• AN/ANH and ARN base modules and ARN Ethernet expansion modules,

which reside on the router

• DCM, which physically attaches to the router’s base module and contains its

own flash memory module

• DCM agent software , whic h opera tes on the Ethernet DCM

• Data collection module middlewa re (DCMMW), which operates on the

router’s base module

• RMON agent software , whic h opera tes on the router’s base module

• Network manag em en t soft w are, which resides on an RMON network

management station

RMON and RMON2 Overview

The RMON network management station sends SNMP

set

and

commands

get

requesting inf ormation from the DCM agent that resides on the Ethernet DCM on the router. The RMON agent sends the requested infor mation to the network management station, which then processes and displays this infor mation on its console.

describe them in more detail.

Data Collection Module (DCM)

The Ethernet DCM, which runs the DCM agent software, physically connects to the BayStack router base module and the ARN Ethernet expansion module. The Ethernet DCM contains a flash memory module for its own boot image and configura tion files.

DCM Agent Software

The DCM agent software resides on a DCM installed on an AN/ANH or ARN router. The DCM agent continually collec ts and analyzes Ethernet data in real time on a single LAN segment (RMON), on groups of LANs (RMON), or on an enterprise network (RMON2). The DCM agent stores the data locally in the Ethernet DCM according to t he RMON specif i cation, defined in RFC 1757, or the RMON2 MIB specificatio n, in compliance with RFC 2021.

You can enable multiple DCM agents running on different segments of the network, with a single network management station controlling and a ccessing them.

RMON and RMON2 Overview

DCM Middleware (DCMMW)

To communicate with the DCM software on the Ethernet DCM, the router uses a software subsys tem, the DCM middleware (DCMMW). This software subs ystem enables and configures an installed Ethernet DCM and allows you to modify the Ethernet DCM configur ation, boot the Ethernet DCM, download the DCM image from the base module to the Ethernet DCM, and disable the Ethe rn et DCM using Site Manager or the BCC. You can use an SNMP-based network management application that suppor ts RMON to view RMON and RMON2 statistics.

RMON Agent Software

The RMON agent software resides on the router’s base module and supports the alarm and ev ent groups on all Bay Networks routers. The RMON agent softwar e also supports the stati stic s and history groups on the ARN 100 router and communicates with the DCMMW software subsystem to access RMON and RMON2 data collected by the Ethernet DCM.

RMON Network Management Software

An RMON net wor k m anag em en t softw are application, also known as a client, runs on a network management station, which can be a workstatio n or PC running UNIX or Windo ws®. Many RMON clients located at va rious locations can simultaneously r etrieve information from an AN/ANH or ARN rout er locat ed on a specific LAN segment within an internetwork. Optivity Analysis for Windows NT® is an example of an RMON network management application.

After you enable the Ethernet DCM on a r outer and the Ethernet DCM is collecting stat istics, you can use the followi ng network management application s to view, analyze, and monitor network RMON and RMON2 statistics:

• Opti vity Analy sis for UNIX and Opti vity LAN app licat ions, whic h are part of

the Optivity Ente rprise

• Opti vity Analysis for Windows NT

Optivity Analysis for UNIX

Optivit y Analysis for UNIX is a set of graphical network management applications bas ed on RMON. These Optivity® applications of fer powerful RMON-based tools that let you view statistics for an enterpri se-wide internetwor k, for specific LAN segments within an internetwork, or for hosts on a LAN segment.

Each RMON tool is a complete application that represents an intelligent implementation of the RMON and RMON2 MIB groups. After the tool requests and receives information from the network management station, it processes the information and displa ys a graph ical summary of network traffic. Each tool is configura ble, so you can obtain exactly the type of information you need.
