A common address pool and an extended address pool are different in address allocation mode
configuration. Configurations of other parameters (such as the domain name suffix and DNS server
address) for them are the same.
Configuring an Address Allocation Mode for a Common Address Pool
You can configure either the static binding or dynamic address allocation for a common 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.
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 a static binding in a common address pool:
