![]() Designated Port : The other port that is not Root Port.Root Port : The port to the Root Bridge.The port classification and their meaning are like below: And then the connected port of the switches are classified. One of the most common name of this mechanisms is STP(Spanning Tree Protocol).Īcording to this protocol, in the switching topology, a Root Bridge is selected. To avoid this unwanted Switching Loops, there are some mechanisms. Because of teh fact that there is no TTL (time to live) mechanism on layer 2, this continues forever. Switches creates broadcast storms from every port and switch rebroadcast again and again. Then, what is Switching Loop? Switching Loop is the situation, in which there are two layer 2 path between two layer 2 endpoint(switch, brigde). Switching Loop is an unwanted problem in a network. pkt format HERE.įor all Packet Tracer Examples and Files, you can check Packet Tracer Labs Page. ![]() You can DOWNLOAD the Packet Tracer example with. In this post, instead of detaily talk about STP (Spanning Tree Protocol), we will focus on a basic Switching Loop topology and how STP mechanism helps to avoid this Switching Loop.
