TATISTICS
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
Errors A count of frames for which transmission on a particular
interface fails due to an internal MAC sublayer transmit
error.
Internal Mac Receive
Errors A count of frames for which reception on a particular
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.
