Object
Late collisions may be a symptom of cabling
problems. A late collision is one that occurred
64 bytes or more into the packet.
Late collisions may be an indication that a
segment is longer than allowed by the wiring
specifications.
A station will believe it has control of the
cable segment if it has already transmitted 64
bytes. If another node at the far end of the
segment has not yet seen the packet, and transmits,
this packet will collide with the first
transmission after the first 64 bytes have been
sent. Ensure that your segment length does not
exceed the maximum length allowed.
Because the location of cabling problems can be very
difficult to detect on an Ethernet network, you may
want to `shorten` an Ethernet segment (remove portions
of the network to isolate problems) until the problems
are no longer seen, and then expand the network until
the problem recurs.
If this counter increments quickly in a short
period of time, it may mean that the network
card is running in half duplex mode, but your
hub or switch port is configured for full duplex
mode. Compare your network card`s configuration
with the port`s configuration.
Late collisions are also included in other
collision-related statistics.
