Appendix C. Example Of Network Configuration Using Loop Detection Function And Its Precautions - Panasonic PN28080K Operation Manual

Appendix C.
Example of configuration using loop detection function
By using the loop detection function, you can prevent a loop failure that is
likely to be caused in a downstream Switching Hub that the user directly
uses.
In addition, if a downstream Switching Hub is connected with a device, such
as a hub without loop detection function, and a loop failure occurs under the
device, the downstream Switching Hub shuts down the corresponding port
to prevent the failure from extending to the entire network.
