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.
