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.
