Table 12 Port Statistics Summary Page - Field Description (continued)

Field	Description
Broadcast Output	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.
Alignment Errors	The number of alignment errors (mis-synchronized data
	packets).
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.
Single Collision Frames	The number of successfully transmitted frames for which
	transmission is inhibited by exactly one collision.
Multiple Collision Frames	A count of successfully transmitted frames for which
	transmission is inhibited by more than one collision.
SQE Test Errors	A count of times that the SQE TEST ERROR message is
	generated by the PLS sublayer for a particular interface.
Deferred Transmissions	A count of frames for which the first transmission
	attempt on a particular interface is delayed because the
	medium was busy.
Late Collisions	The number of times that a collision is detected later
	than 512 bit-times into the transmission of a packet.
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.
Internal Mac Transmit	A count of frames for which transmission on a particular
Errors	interface fails due to an internal MAC sublayer transmit
	error.
Internal Mac Receive	A count of frames for which reception on a particular
Errors	interface fails due to an internal MAC sublayer receive
	error.
Frames Too Long	A count of frames received on a particular interface that
	exceed the maximum permitted frame size.
Carrier Sense Errors	The number of times that the carrier sense condition
	was lost or never asserted when attempting to transmit
	a frame.
