Aim With the studies on switch and route technology in the campus network
an effective visit to the workstation can be taken and controlled. Methods On the basis of OSI of network
some experiments such as classification and controlling can be done with the network adapter MAC address and IP address in switch and router. Results The key controllable technology of MAC address and IP address can be obtained as a result of the experiment. Conclusion The good mastery of these key technology lays a solid foundation for the normal management of the campus network.
