Common Problems and Solutions

Symptom

Possible Cause

Resolution

Poor performance or excessive
errors

Duplex autonegotiation mismatch.

Refer to the switch software
configuration guide for
information on identifying
autonegotiation mismatches.

Cabling distance exceeded

•

Port statistics show excessive
frame check sequence (FCS),
late-collision, or alignment
errors.

•

For 10/100 and
10/100/1000BASE-T
connections:

–

The distance between the
port and the attached device
exceeds 328 feet (100
meters).

–

If the switch is attached to a
repeater, the total distance
between the two end
stations exceeds the cabling
guidelines.

•

For SFP port connections:

–

The distance between the
SFP port and the attached
device exceeds the SFP
cabling guidelines.

•

Refer to the switch software
configuration guide for
information on displaying
port statistics.

•

Reduce the cable length to
within the recommended
distances.

•

Refer to your repeater
documentation for cabling
guidelines.

•

Refer to your SFP
documentation for cabling
guidelines.

Bad adapter in attached device

•

Excessive errors found in port
statistics.

•

STP checking for possible
loops.

•

Run adapter card diagnostic
utility.

•

Wait 30 seconds for the port
LED to turn green.
