Configuring the RMON Statistics Function

Configuring the RMON statistics function helps to collect and record statistics of an interface.

RMON statistics can be divided into the Ethernet statistics function and historical sampling function.

Ethernet statistics function (corresponding to the statistics group in RMON MIB): The system collects the statistics about basic traffic on monitored interfaces.
Historical sampling function (corresponding to the history group in RMON MIB): The system samples the interface statuses on the network periodically and stores the information for later queries.

Run system-view
The system view is displayed.
Run interface interface-type interface-number
The interface on which traffic statistics are collected is specified and the view of the interface is displayed.
Run rmon-statistics enable
The RMON statistics function is enabled on the interface.

If the RMON statistics function is not enabled, the Ethernet statistics and historical sampling functions cannot be enabled.
Run rmon statistics entry-number [ owner owner-name ]
The Ethernet statistics function is configured.
Run rmon history entry-number buckets number interval sampling-interval [ owner owner-name ]
The historical sampling function is configured.

To reduce the impact of RMON on system performance, the sampling interval should be set to be longer than 10 seconds, and the historical sampling function should not be configured multiple times on an interface. RMON suggests that each monitored interface can be configured with more than two historical samples and the sampling interval should be 30 seconds.
