When STP detects a local loopback, it determines that a network storm occurs and will trigger shutdown of the local interface to prevent the storm from affecting services on the entire network; however, services on the shutdown interface will be interrupted.
After STP detects a loopback on an interface, the device shuts down the interface to prevent a loop.
