network configuration protocol optimized and developed basing on the BOOTP, functions to solve the above mentioned problems. ¾ DHCP Working Principle DHCP works via the "Client/Server" communication mode. The Client applies to the Server for configuration. The Server assigns the configuration information, such as the IP address, to the Client, so as to reach a dynamic employ of the network source. A Server can assign the IP address for several Clients, which is illustrated in the following figure. Figure 13-5 Network diagram for DHCP-snooping implementation For 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 to the specific Client (e.g.: WWW Server) via the DHCP Server. (2) Automatically assign the IP address: DHCP Server assigns the IP address without an expiration time limitation to the Clients. (3) Dynamically assign the IP address: DHCP Server assigns the IP address with an expiration time. When the time for the IP address expired, the Client should apply for a new one. The most Clients obtain the IP addresses dynamically, which is illustrated in the following figure. 151
