Remote monitoring
Introduction
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

Overview

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:
Group 1: Statistics
Group 2: History
Group 3: Alarms
Group 9: Events
RMON group 1—statistics
The switch supports collection of Ethernet statistics as outlined in the RMON statistics MIB, in reference to
etherStatsTable. You can enable RMON statistics on a per-port basis, and you can view them using the following
command: /stat/port x/rmon. RMON statistics are sampled every second, and new data overwrites any old
data on a given port.
NOTE: RMON port statistics must be enabled for the port before you can view RMON statistics.
Configuring RMON Statistics (CLI example)
1. Enable RMON on each port where you wish to collect RMON statistics.
>> /cfg/port 23/rmon
>> Port 23 RMON# ena
>> Port 23 RMON# apply
>> Port 23 RMON# save
(Select Port 23 RMON)
(Enable RMON)
(Make your changes active)
(Save for restore after reboot)
