RMON Statistics

RMON Statistics 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 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 passing through each port. Values displayed have been accumulated since the last system reboot.

Parameter	Description
Drop Events	The total number of events in which packets were dropped due
	to lack of resources.
Received Bytes	Total number of bytes of data received on the network. This
	statistic can be used as a reasonable indication of Ethernet
	utilization.
Received Frames	The total number of frames (bad, broadcast and multicast)
	received.
Broadcast Frames	The total number of good frames received that were directed to
	the broadcast address. Note that this does not include multicast
	packets.
Multicast Frames	The total number of good frames received that were directed to
	this multicast address.
CRC/Alignment	The number of frames received with CRC/alignment errors
Errors	(FCS or alignment errors).
Undersize Frames	The total number of frames received that were less than 64
	octets long (excluding framing bits, but including FCS octets)
	and were otherwise well formed.
Oversize Frames	The total number of frames received that were longer than 1518
	octets (excluding framing bits, but including FCS octets) and
	were otherwise well formed.
Fragments	The total number of frames received that were less than 64
	octets in length (excluding framing bits, but including FCS
	octets) and had either an FCS or alignment error.
Jabbers	The total number of frames received that were longer than 1518
	octets (excluding framing bits, but including FCS octets), and
	had either an FCS or alignment error.
