Description
The number of times that a collision is detected later than 512
bit-times into the transmission of a packet.
A count of frames received on a particular interface that are an
integral number of octets in length but do not pass the Frame
Check Sequence (FCS). This count does not include frames
received with a frame-too-long or frame-too-short error.
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.
The number of successfully transmitted frames for which
transmission is inhibited by exactly one collision.
A count of frames for which transmission on a particular interface
fails due to an internal MAC sublayer transmit error.
A count of successfully transmitted frames for which transmission
is inhibited by more than one collision.
The number of times that the carrier sense condition was lost or
never asserted when attempting to transmit a frame.
A count of times that the SQE TEST ERROR message is
generated by the PLS sublayer for a particular interface.
A count of frames received on a particular interface that exceed
the maximum permitted frame size.
A count of frames for which the first transmission attempt on a
particular interface is delayed because the medium is busy.
A count of frames for which reception on a particular interface fails
due to an internal MAC sublayer receive error.
The total number of events in which packets were dropped due to
lack of resources.
The total number of frames received that were longer than 1518
octets (excluding framing bits, but including FCS octets) and had
either an FCS or alignment error.
Total number of bytes of data received on the network. This
statistic can be used as a reasonable indication of Ethernet
utilization.
The best estimate of the total number of collisions on this Ethernet
segment.
The total number of frames (bad, broadcast, and multicast)
received.
The total number of good frames received that were directed to
the broadcast address. This does not include multicast packets.
