Displaying RMON Statistics

Use the RMON Statistics screen to display key statistics for each port from RMON
group 1. (RMON groups 2, 3 and 9 can only be accessed using SNMP management
software.) The following screen displays the overall statistics on traffic passing
through each port. RMON statistics provide access to a broad range of statistics,
including a total count of different frame types and sizes passing through each port.
Values displayed have been accumulated since the last system reboot.
