Enabling the Global Address Pool Mode on Interface(s)
You can configure the global address pool mode on the specified or all interfaces of a DHCP server.
After that, when the DHCP server receives DHCP packets from DHCP clients through these interfaces,
it assigns IP addresses in the global address pool to the DHCP clients.
Follow these steps to configure the global address pool mode on interface(s):

Configuring an Address Allocation Mode for the Global Address Pool
You can configure either the static IP address allocation mode or the dynamic IP address allocation
mode for a global address pool, and only one mode can be configured for one DHCP global address
pool.
For dynamic IP address allocation, you need to specify the range of the IP addresses to be dynamically
assigned. But for static IP address binding, you can regard that the IP address statically bound to a
DHCP client comes from a special DHCP address pool that contains only one IP address.
Configuring the static IP address allocation mode
Some DHCP clients, such as WWW servers, need fixed IP addresses. This can be achieved by binding
IP addresses to the MAC addresses of these DHCP clients. When such a DHCP client requests an IP
