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.

Transmit Errors*
The number of frames for which transmission failed due to an
internal MAC sublayer transmit error.

never asserted when attempting to transmit a frame.
Frames Too Long The number of frames received that exceed the maximum
permitted frame size.

Receive Errors*
The number of frames for which reception failed due to an internal
MAC sublayer receive error.

supported by the internal chip set.
