RMON and RMON2 Overview

Data Collection Module (DCM)

The Ethernet DCM 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 configuration files. The Ethernet DCM runs

the DCM agent software.

DCM Agent Software

The DCM agent software resides on a DCM installed on an AN/ANH or ARN

router. The DCM agent continually collects 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 the RMON specification, defined in RFC 1757, or the

RMON2 MIB specification, 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 accessing

them.

DCM Middleware (DCMMW)

To communicate with the DCM software on the Ethernet DCM, the router uses a

software subsystem, the DCM middleware (DCMMW). This software subsystem

enables and configures an installed Ethernet DCM and allows you to modify the

Ethernet DCM configuration, boot the Ethernet DCM, download the DCM image

from the base module to the Ethernet DCM, and disable the Ethernet DCM using

Site Manager. You can use an SNMP-based network management application that

supports 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 event groups on all Bay Networks routers. The RMON agent software

also supports the statistics 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.
