Diagnosing Problems

Table 3-1

Common Problems and Solutions

Symptom

Possible Cause

Resolution

Poor performance or
excessive errors.

Duplex autonegotiation mismatch.

Refer to the Catalyst 2950
Desktop Switch Software
Configuration Guide for
information about identifying
autonegotiation mismatches.

Cabling distance exceeded.

•

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

•

Refer to the Catalyst 2950
Desktop Switch Software
Configuration Guide for
information about
displaying port statistics.

•

For 10BASE-T, 100BASE-TX,
and 1000BASE-T connections:

–

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

•

Reduce cable length to
within the recommended
distances.

–

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

•

Refer to your repeater
documentation for cabling
guidelines.

•

For GBIC port connections: The
distance between the GBIC port
and the attached device exceeds
the GBIC cabling guidelines.

•

Refer to your GBIC
documentation for cabling
guidelines.

Bad adapter in attached device.

•

Excessive errors found in port
statistics.

•

Run adapter card diagnostic
utility.

Spanning Tree Protocol (STP)
checking for possible loops.

Wait 30 seconds for port status
LED to turn green.
