Description
For 10 Mbps ports, this counter records alignment errors
(mis-synchronized data packets). For 100 Mbps ports, this
counter records the sum of alignment errors and code errors
(frames received with rxerror signal).
The number of frames received that are an integral number
of octets in length but do not pass the FCS check.
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 that one collision.
A count of times that the SQE TEST ERROR message is
generated by the PLS sublayer.
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.
The number of frames for which transmission failed due to
excessive collisions.
The number of frames for which transmission failed due to
an internal MAC sublayer transmit error.
The number of times that the carrier sense condition was lost
or never asserted when attempting to transmit a frame.
The number of frames received that exceed the maximum
permitted frame size.
The number of frames for which reception failed due to an
internal MAC sublayer receive error.
