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 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 that one collision.

SQE Test Errors* 

A count of times that the SQE TEST ERROR message is 
generated by the PLS sublayer.

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* 

The number of frames for which transmission failed due to 
excessive collisions.

Internal Mac Transmit Errors*

The number of frames for which transmission failed due to 
an internal MAC sublayer transmit error.

Carrier Sense Errors* 

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 Errors*

The number of frames for which reception failed due to an 
internal MAC sublayer receive error.

*

 The reported values will always be zero because these statistics are not supported by the internal chip 

set.
