	Table 3-10 Port Statistics (Continued)
Parameter	Description
Transmit Multicast Packets	The total number of packets that higher-level protocols requested be
	transmitted, and which were addressed to a multicast address at this
	sub-layer, including those that were discarded or not sent.
Transmit Broadcast Packets	The total number of packets that higher-level protocols requested be
	transmitted, and which were addressed to a broadcast address at this
	sub-layer, including those that were discarded or not sent.
Transmit Discarded Packets	The number of outbound packets which were chosen to be discarded even
	though no errors had been detected to prevent their being transmitted.
	One possible reason for discarding such a packet could be to free up
	buffer space.
Transmit Errors	The number of outbound packets that could not be transmitted because of
	errors.
Etherlike Statistics
Alignment Errors	The number of alignment errors (missynchronized data packets).
Late Collisions	The number of times that a collision is detected later than 512 bit-times
	into the transmission of a packet.
FCS Errors	A count of frames received on a particular interface that are an integral
	number of octets in length but do not pass the FCS check. This count does
	not include frames received with frame-too-long or frame-too-short error.
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.
