RMON Overview

© Copyright Lenovo 2015
Remote Monitoring (RMON) allows network devices to exchange network
monitoring data.
RMON performs the following major functions:
 Gathers cumulative statistics for Ethernet interfaces
 Tracks a history of statistics for Ethernet interfaces
 Creates and triggers alarms for user-defined events
The RMON MIB provides an interface between the RMON agent on the switch and
an RMON management application. The RMON MIB is described in RFC 1757.
The RMON standard defines objects that are suitable for the management of
Ethernet networks. The RMON agent continuously collects statistics and
proactively monitors switch performance. RMON allows you to monitor traffic
flowing through the switch.
The switch supports the following RMON Groups, as described in RFC 1757:
 RMON Group 1–Statistics
 RMON Group 2–History
 RMON Group 3–Alarms
 RMON Group 9–Events
