network configuration protocol optimized and developed basing on the BOOTP, functions to solvethe above mentioned problems.‣ DHCP Working PrincipleDHCP works via the “Client/Server” communication mode. The Client applies to the Server forconfiguration. The Server assigns the configuration information, such as the IP address, to theClient, so as to reach a dynamic employ of the network source. A Server can assign the IPaddress for several Clients, which is illustrated in the following figure.Figure 11-5 Network diagram for DHCP-snooping implementationFor different DHCP Clients, DHCP Server provides three IP address assigning methods:(1) Manually assign the IP address: Allows the administrator to bind the static IP address tothe specific Client (e.g.: WWW Server) via the DHCP Server.(2) Automatically assign the IP address: DHCP Server assigns the IP address without anexpiration time limitation to the Clients.(3) Dynamically assign the IP address: DHCP Server assigns the IP address with anexpiration time. When the time for the IP address expired, the Client should apply for anew one.The most Clients obtain the IP addresses dynamically, which is illustrated in the following figure.143
