2.2.3 Configuring 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.

2.2.4 Configuring How to Assign IP Addresses in a Global Address Pool

You can specify to bind an IP address in a global address pool statically to a DHCP
client or assign IP addresses in the pool dynamically to DHCP clients as needed. In
the global address pool, you can bind an IP address statically to a DHCP client and
assign other IP addresses in the pool dynamically to DHCP clients.
For dynamic IP address assigning, you need to specify the range of the IP addresses
to be dynamically assigned. But for static IP address binding, you can consider an IP
address statically bound to a DHCP client coming from a special DHCP address pool
that contains only one IP address.
I. Configuring to assign IP addresses by static binding
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 applies for an IP address, the DHCP server searches for the IP
address corresponding to the MAC address of the DHCP client and assigns the IP
address to the DHCP client.
