This paper on the characteristics of the work, design ideas, as well as the entire work design is expounded. Network management, isa work key ess factors. Highly efficient and orderly management, work optimal operation, network play the best benefits. This article from the P address allocation and VLAN programming, the use of the protocol user authentication and access control list through the configuration of work data flow control three aspects of the work management technology research. Address management is very important in the world. Wrong understanding will lead to very serious consequences, ina work, address management structure design is very easy to cause anization to the work renumbering. This will not only cause the long time shutdown, but also to address phase induced instability. While a good address management structure isnot need to spend any cost, only requires careful planning and understanding of the problem. Each VLAN internal broadcast and unicast traffic will not be forwarded to the other VLAN, thereby contributing to the control of flow, reduce equipment investment, simplifying
