Description
The length of the output packet queue (in 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.
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.
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.
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.
The number of alignment errors (missynchronized data packets).
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.
The number of successfully transmitted frames for which transmission
is inhibited by exactly one collision.
A count of successfully transmitted frames for which transmission is
inhibited by more than one collision.
A count of times that the SQE TEST ERROR message is generated by the
PLS sublayer for a particular interface.
A count of frames for which the first transmission attempt on a
particular interface is delayed because the medium was busy.
The number of times that a collision is detected later than 512 bit-times
into the transmission of a packet.
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.
A count of frames for which transmission on a particular interface fails
due to an internal MAC sublayer transmit error.
to an internal MAC sublayer receive error.
A count of frames received on a particular interface that exceed the
maximum permitted frame size.
The number of times that the carrier sense condition was lost or never
asserted when attempting to transmit a frame.
