Users can access the Internet only with a valid IP address. Therefore, an access device must support unified IP address allocation and management.
Manually Allocating IP Addresses
You can directly configure an IP address on your computer. This mode is suitable for the server used for certain purposes or for users with special requirements, such as Web servers and switchs. To prevent an IP address from being spoofed, configure IP/VLAN or IP/PVC binding on the access server.
Allocating IP Addresses Using DHCP
The Dynamic Host Configuration Protocol (DHCP) works in client/server mode. The administrator sets an IP address range on a DHCP server. With DHCP, a client can apply for configuration information from a DHCP server, including the assigned IP address, the subnet mask, and the default gateway. The DHCP server can reply the configuration information based on a certain policy.
