	Management Guide

Parameter	Description
Alignment Errors	For 10 Mbps ports, this counter records alignment errors (mis-
	synchronized data packets). For 100 Mbps ports, this counter records
	the sum of alignment errors and code errors (frames received with
	rxerror signal).
FCS Errors	The number of frames received that are an integral number of octets in
	length but do not pass the FCS check.
Single Collision Frames1	The number of successfully transmitted frames for which transmission
	is inhibited by exactly one collision.
Multiple Collision Frames1	A count of successfully transmitted frames for which transmission is
	inhibited by more that one collision.
SQE Test Errors1	A count of times that the SQE TEST ERROR message is generated by
	the PLS sublayer.
Deferred Transmissions1	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 Collisions1	The number of frames for which transmission failed due to excessive
	collisions.
Internal Mac Transmit Errors1	The number of frames for which transmission failed due to an internal
	MAC sublayer transmit error.
Carrier Sense Errors1	The number of times that the carrier sense condition was lost or never
	asserted when attempting to transmit a frame.
Frames Too Long	The number of frames received that exceed the maximum permitted
	frame size.
Internal Mac Receive Errors1	The number of frames for which reception failed due to an internal
	MAC sublayer receive error.

1: The values will always be zero because these statistics are not supported by the internal chip set.
