Parameter	Description
Internal Mac	The number of frames for which transmission failed due to an
Transmit Errors*	internal MAC sublayer transmit error.
Carrier Sense Errors*	The number of times that the carrier sense condition was lost or
	never asserted when attempting to transmit a frame.
Frames Too Long	The number of frames received that exceed the maximum
	permitted frame size.
Internal Mac	The number of frames for which reception failed due to an internal
Receive Errors*	MAC sublayer receive error.

*The reported values will always be zero because these statistics are not supported by the internal chip set.

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.
