DHCP Working Principle, Dynamic Host Configuration Protocol,

Page 291 highlights

PC should be updated with a few configurations. DHCP(Dynamic Host Configuration Protocol, the network configuration protocol optimized and developed basing on the BOOTP, functions to solve the above mentioned problems.  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. For details about the DHCP Server function, please refer to 10.4 DHCP Server. Figure 14-5 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. 280

Dynamic Host Configuration Protocol, the

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. For details about the DHCP
Server function, please refer to

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.
