2.5.3 Configuring an Address Allocation Mode

Caution:
You can configure either the static binding or dynamic address allocation for an
address pool as needed.
It is required to specify an address range for the dynamic address allocation. A static
binding is a special address pool containing only one IP address.
I. Configuring manual address allocation
Some DHCP clients such as a WWW server need fixed IP addresses. You can create a
static binding of a client's MAC or ID to IP address in the DHCP address pool.
When the client with the MAC address or ID requests an IP address, the DHCP server
will find the IP address from the binding for the client.
A DHCP address pool now supports only one static binding, which can be a MAC-to-IP
or ID-to-IP binding.
Follow these steps to configure the static binding in a DHCP address pool:
Enter system view
Enter DHCP address pool
