Configuration using Loop
Detection Function and Its
Precautions
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.
