Abstract: A STP arithmetic which is used to eliminate the redundant connection between switches is introduced and some concerned concepts and knowledge arc generally explained.We also introduce a simple and practical method which is used to determine the state of the ports on the switches and which is abstracted during the practice . Finally several applied examples are listed to account for the method.
