About Spanning Tree Protocol

1. Spanning Tree Protocol (STP) Configuration ?

- STP refers to a network protocol that logically maintains only one active connection in a  duplex network and activates another connection only when it is recognized that the  existing connection is broken.

2. Effects of STP Configuration

 - It can logically prevent the loop topology by changing a specific port to a blocked state in the loop

   topology network

-It can prevent repeated flooding of broadcasts on the network when it goes out of the loop topology.

-Since it is possible to change the route when the network connection in a direction is disconnected, the

   maintenance is easy.

3. Problems without STP Configuration

-In the loop topology network, the switch repeats receiving the broadcast it has sent and sending the          broadcast packet again

-Existing packets are continuously sent and received, and new packets from the device are also                    transmitted

- Explosive increase in the number of packets handled → Increase in CPU occupancy → Network overload     → The network goes down
