Port Configuration

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.
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.
