Configuration Guide Configuring RMON
4 Configuring RMON
4.1 Overview
The Remote Network Monitoring (RMON) aims at resolving problems of managing local area networks (LANs) and remote
sites by using one central point. In RMON, network monitoring data consists of a group of statistics and performance
indicators, which can be used for monitoring the network utilization, so as to facilitate network planning, performance
optimization, and network error diagnosis.
RMON is mainly used by a managing device to remotely monitor and manage managed devices.
The RMON function is not supported on AP110-W or AP120-W.

4.2 Applications
Collecting Statistics on Information of
a Monitored Interface
Applies four functions of RMON to an interface to monitor the network communication
of the interface.
4.2.1 Collecting Statistics on Information of a Monitored Interface
Scenario
The RMON Ethernet statistics function is used to monitor accumulated information of an interface, the history statistics
function is used to monitor the packet count of an interface within each monitoring interval, and the alarm function is used to
immediately acquire packet count exceptions of an interface. The following figure shows the networking topology.
