Advantages:
•
Failure of any single Ethernet cable does not disrupt network communication
•
Additional nodes or heavier network traffic affects network performance less than the line
topology
•
Simple installation
•
Ideal for a local networking solution
Note
Network configuration and programming require careful consideration. Visit

for information about exploiting link redundancy and
automatically improving reliability.
Disadvantages:
•
Network traffic patterns can make troubleshooting difficult
•
Requires an external switch
Note
For information about daisy-chaining power, refer to
Star Topology
In a star topology, the host communicates directly with each node through the external switch.
You must use an external switch in a star topology; for network synchronization, you must use
an external IEEE 802.1AS switch. Redundant links are recommended, but optional, in this
topology. You must configure the network properly with a recommended external switch
before creating redundant links in the network. Refer to
information about what to look for in an external IEEE 802.1AS switch.
