Troubleshooting 19-5
Table 19-10 Troubleshooting Improper Network Cabling and Topology
DESCRIPTION PROBLEMS AND CORRECTIVE ACTION
Faulty cables Using faulty network cables may affect data rates and have an impact
on your network performance. Replace with new standard network
cables.
Non-standard
network cables Non-standard cables may increase the number of network collisions
and cause other network problems that affect your network
performance; refer to
Chapter 2 .
Cabling Length If you use longer cables than are needed, transmission quality may be
affected.
The network cables should not be longer than the limit of 100 meters.
Too many hubs
between the
computers in the
network Too many hubs (or repeaters) between the connected computers in
the network may increase the number of network collision or other
network problems. Remove unnecessary hubs from the network.
A loop in the data
path A data path loop forms when there is more than one path or route
between two networked computers. This results in broadcast storms
that will severely affect your network performance. Make sure there
are no loops in your network topology.
