Displaying RMON Statistics

Use the RMON Statistics screen to display key statistics for each port or

media module 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.
