RMON Statistics

RMON Statistics 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 such as AccView.) 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 Errors	For 10Mbps ports, the counter records CRC/alignment errors (FCS or
	alignment errors). For 100Mbps ports, the counter records the sum of
	CRC/alignment errors and code errors (frame received with rxerror
	signal).
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.
