2.1.1 Introduction
Remote Monitoring (RMON) is a type of IETF-defined MIB. It is the most important
enhancement to the MIB II standard. It allows you to monitor traffic on network
segments and even the entire network.
RMON is implemented based on the Simple Network Management Protocol (SNMP)
and is fully compatible with the existing SNMP framework.
RMON provides an efficient means of monitoring subnets and allows SNMP to monitor
remote network devices in a more proactive and effective way. It reduces traffic
between network management station (NMS) and agent, facilitating large network
management.
RMON comprises two parts: NMSs and agents running on network devices.
Each RMON NMS administers the agents within its administrative domain.
An RMON agent resides on a network monitor or probe for an interface. It monitors
and gathers information about traffic over the network segment connected to the
interface to provide statistics about packets over a specified period and good
packets sent to a host for example.

2.1.2 Working Mechanism

RMON allows multiple monitors. A monitor provides two ways of data gathering:
Using RMON probes. NMSs can obtain management information from RMON
probes directly and control network resources. In this approach, RMON NMSs can
obtain all RMON MIB information.
Embedding RMON agents in network devices such as routers, switches, and hubs
to provide the RMON probe function. RMON NMSs exchange data with RMON
