Analyzing Network Performance

6-6 Cajun P220G Switch Configuration and Operation G uide

CRC and
Alignment
Errors

Count of the number of times that
the number of bits in a frame
cannot be divided by 8 (that is,
cannot be broken into legal octets),
and that contain a Frame Check
Sequence validation error. Typically
caused by turning equipment on or
off, and by noise on twisted pair
segments. These errors can also
result from configuring a network
that does not comply with 802.3
standards. In a standards-compliant
Ethernet network, CRC or
alignment errors represent transit
and receive bit errors.

The Ethernet standard allows 1 in
10

8

bit error rate, but you should

expect performance to be less than
1 in 10

12

packets. Rates in excess of

one error per one thousand packets
indicate a serious problem.

Cause: Defect at the transmitting
station.

Action: Use port error statistics to
isolate the problem. Check the
transceiver or adapter card
connected to the port where the
problem seems to originate. Also
check the cable and cable
connections for damage.

Cause: Turning equipment on or
off. This should cause only a few
errors.

Action: Normal operation, no
action required.

Cause: Damaged cables.

Action: Check cables for damage.

Cause: Interference on network
cabling.

Action: Inspect cable runs to see if
they are too close to noisy devices,
and check for problems with
network devices.

Undersize
and
Oversize
Packets

Counts malformed packets that are
most often the result of software
errors.

Cause: A transceiver on your
network is adding bits to the
packets transmitted by the attached
station.

Action: Use a network analyzer to
identify the transceiver which is
causing the problem. If necessary,
replace transceiver, network
adapter, or station.

Cause: There is excessive noise on
the cable.

Action: Check for cables to close to
noisy electronic equipment,
improper cabling, damaged cable,
or malfunctioning network
equipment.
