Received Unicast Packets The number of subnetwork-unicast packets delivered to a higher-layer
protocol.
Received Multicast Packets The number of packets, delivered by this sub-layer to a higher (sub-
)layer, which were addressed to a multicast address at this sub-layer.
Received Broadcast Packets The number of packets, delivered by this sub-layer to a higher (sub-
)layer, which were addressed to a broadcast address at this sub-layer.
Transmitted Octets The total number of octets transmitted out of the interface, including
framing characters.
Transmitted Errors The number of outbound packets that could not be transmitted
because of errors.
Transmitted 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.
Transmitted 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.
Received Discarded Packets The number of inbound packets which were chosen to be discarded
even though no errors had been detected to prevent their being
deliverable to a higher-layer protocol. One possible reason for
discarding such a packet could be to free up buffer space.
Transmitted 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.
Transmitted 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.
Etherlike Statistics
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.
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.
Deferred Transmissions A count of frames for which the first transmission attempt on a
particular interface is delayed because the medium was busy.
Frames Too Long A count of frames received on a particular interface that exceed the
maximum permitted frame size.
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.
Internal MAC Transmit
Errors
A count of frames for which transmission on a particular interface fails
due to an internal MAC sublayer transmit error.
Pause Frames Input If the counter is incrementing this means that the port is receving
pause frames.
