	Table 3-9 Port Statistics (Continued)
Parameter		Description
Excessive Collisions		A count of frames for which transmission on a particular interface fails due
		to excessive collisions. This counter does not increment when the
		interface is operating in full-duplex mode.
Single Collision Frames		The number of successfully transmitted frames for which transmission is
		inhibited by exactly one collision.
Internal MAC Transmit Errors		A count of frames for which transmission on a particular interface fails due
		to an internal MAC sublayer transmit error.
Multiple Collision Frames		A count of successfully transmitted frames for which transmission is
		inhibited by more than one collision.
Carrier Sense Errors		The number of times that the carrier sense condition was lost or never
		asserted when attempting to transmit a frame.
SQE Test Errors		A count of times that the SQE TEST ERROR message is generated by the
		PLS sublayer for a particular interface.
Frames Too Long		A count of frames received on a particular interface that exceed the
		maximum permitted frame size.
Deferred Transmissions		A count of frames for which the first transmission attempt on a particular
		interface is delayed because the medium was busy.
Internal MAC Receive Errors		A count of frames for which reception on a particular interface fails due to
		an internal MAC sublayer receive error.
RMON Statistics
Drop Events		The total number of events in which packets were dropped due to lack of
		resources.
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.
Received Bytes		Total number of bytes of data received on the network. This statistic can
		be used as a reasonable indication of Ethernet utilization.
Collisions		The best estimate of the total number of collisions on this Ethernet
		segment.
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		The number of CRC/alignment 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.
