In a ring topology, the host communicates with all nodes through the most effective path.

You must use an external switch in a ring topology. You must configure the network properly with a recommended external switch before creating redundant links in the network. Refer to the External Switch Requirements section for information about what to look for in an external switch.

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.

Disadvantages:

  • Network traffic patterns can make troubleshooting difficult
  • Requires an external switch
