Example of configuration using the 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.
