Etherlike Statistics
Alignment Errors For 10 Mbps ports, see counts of alignment errors
(mis-synchronized data packets). For 100 Mbps ports, see counts
of the sum of alignment errors and code errors (frames received
with rxerror signal).
FCS Errors See the number of frames received that are an integral number of
octets in length but do not pass the FCS check.
Single Collision Frames See the number of successfully transmitted frames for which
transmission is inhibited by exactly one collision.
Multiple Collision Frames See a count of successfully transmitted frames for which
transmission is inhibited by more that one collision.
SQE Test Errors See a count of times that the SQE TEST ERROR message is
generated by the PLS sublayer.
Deferred Transmissions See a count of frames for which the first transmission attempt on
a particular interface is delayed because the medium was busy.
Late Collisions See the number of times that a collision is detected later than 512
bit-times into the transmission of a packet.
Excessive Collisions See the number of frames for which transmission failed due to
excessive collisions.
Internal MAC Transmit
Errors
See the number of frames for which transmission failed due to an
internal MAC sublayer transmit error.
Carrier Sense Errors See the number of times that the carrier sense condition was lost
or never asserted when attempting to transmit a frame.
Frames Too Long See the number of frames received that exceed the maximum
permitted frame size.
Internal MAC Receive
Errors
See the number of frames for which reception failed due to an
internal MAC sublayer receive error.
