7.Loop Prevention Setting

** 1.Loop Prevention Setting**
The loop is the topology structure of the ring formed by the network of the switch. The loop will cause the Intranet broadcast storm, which will consume a lot of CPU and line bandwidth of the switch, and even cause equipment crash and network paralysis.
Click on the navigation bar: Configure- -> Loop Protection

Explain:
The network loop at the time interval is monitored as a periodic interval
After the loop is found, the exchange opportunity starts the processing mechanism, and the port will automatically return to normal after that time.
1.Instance
1, first switch loop detection function open, the port 3,4 with network cable connected to another switch form loop or ring, appear below (because the loop cause network paralysis, not necessarily refresh the figure), the corresponding loop port light will slow flash, loop detection does not prevent loop, forming loop switch network will be paralyzed
