2.3 Interface Address Pool-based DHCP Server Configuration

Caution:
In the interface address pool mode, after the addresses in the interface address pool
have been assigned, the DHCP server picks IP addresses from the global interface
address pool containing the segment of the interface address pool and assigns them
to the DHCP clients. As a result, the IP addresses obtained from global address pools
and those obtained from interface address pools are not in the same network segment,
so the clients cannot interoperate with each other.
In the interface address pool mode, if the IP addresses in the same address pool are
required to be assigned to the clients on the same VLAN interface, the number of
clients that obtain IP addresses automatically cannot exceed the number of the IP
addresses that can be assigned in the interface address pool.
2.3.1 Configuration Overview
An interface address pool is created when the interface is assigned a valid unicast IP
address and you execute the dhcp select interface command in interface view. The
IP addresses contained in it belong to the network segment where the interface
resides in and are available to the interface only.
You can perform certain configurations for DHCP address pools of an interface or
multiple interfaces within specified interface ranges. Configuring for multiple interfaces
eases configuration work load and makes you to configure in a more convenient way.
