RMON Statistics

Remote Monitoring (RMON) is an extension to the Simple Network Management Protocol (SNMP) which provides network traffic statistics. RMON defines current and historical MAC-layer statistics and control objects, allowing real-time information to be captured across the entire network. The system provides a means to collect the statistics defined in RMON and to view the results using the Web management interface. There is no SNMP management interface in the system.

NOTE: The PowerConnect™ 2708/2716/2724/2748 devices support one RMON group for Ethernet statistics.

The RMON Statistics page contains links for viewing network information from a remote location. To open, click RMON Statistics in the tree view.

Interface — Specifies the port or LAG for which statistics are displayed. Refresh Rate — Amount of time that passes before the statistics are refreshed.

Drop Events — Number of dropped events that have occurred on the interface since the system was last reset.
