cpqNicIfPhysAdapterCarrierSenseErrors

The number of packets transmitted with carrier
sense errors:  This counter contains the number
of times that the carrier sense signal from the
physical layer interface was not asserted or was
de-asserted during transmission of a packet without
collision.
              
The carrier sense signal is an ongoing activity
of a data station to detect whether or not another
station is transmitting.  Carrier sense errors
are detected when a station transmits a frame and
does not detect its own signal on the wire.
              
If you receive carrier sense errors, check the
following:
              
Failing cable: Packet data traveling through
shorted or damaged cabling may cause a signal loss.
Ensure that your cable is working and plugged in
properly.
              
Segment not grounded properly: Improper grounding
of a segment may allow ground-induced noise to
interrupt the signal.  Ensure that you have
properly grounded all segments.
              
Noisy cable: Interference or noise produced by
motors or other devices can interrupt the signals.
              
Deaf/partially deaf node: A faulty station that
cannot hear the activity is considered a deaf node.
If you suspect a deaf node, the network interface
card should be replaced.
              
Failing hub, switch, or controller: Repeaters,
switches and controllers can disrupt the network
signal, transmit erroneous signals on the wire,
or ignore incoming packets.  Perform the following
steps:
              
1.  Swap out the adapter, adapter cable, and
    adapter attachment point, one at a time.
    If you find a faulty component, replace it.
              
2.  If none of the items listed above help you
    isolate the problem, you may need to replace
    the switch or hub.  Use a network analyzer
    to isolate the problem area.
