Transmit Unicast Packets The total number of packets that higher-level
protocols requested be transmitted to a
subnetwork-unicast address, including those that
were discarded or not sent.
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.
