Common Problems and Their Solutions

Symptom

Possible Cause

Resolution

Poor performance or excessive
errors

Duplex autonegotiation mismatch.

See 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 10/100/1000BASE-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 module port
connections:

–

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

•

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

•

Reduce the cable length to
within the recommended
distances.

•

See your repeater
documentation for cabling
guidelines.

•

See your SFP module
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.
