Inthe global address pool, you can bind an IP address statically to a DHCP client andassign other IP addresses in the pool dynamically to DHCP clients.For dynamic IP address assigning, you need to specify the range of the IP addressesto be dynamically assigned. But for static IP address binding, you can consider an IPaddress statically bound to a DHCP client coming from a special DHCP address poolthat contains only one IP address.I. Configuring to assign IP addresses by static bindingSome DHCP clients, such as WWW servers, need fixed IP addresses. This can beachieved 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 forthe IP address corresponding to the MAC address of the DHCP client and assigns theIP address to the DHCP client.Currently, only one IP address in a global DHCP address pool can be statically boundto a MAC address.Follow these steps to configure to assign IP addresses by static binding:
