2-16Configuring the Interface Address Pool Based DHCP ServerIn the interface address pool mode, after the addresses in the interface address pool have beenassigned, the DHCP server picks IP addresses from the global interface address pool containing thenetwork segment of the interface address pool and assigns them to the DHCP clients. As a result, theIP addresses obtained from global address pools and those obtained from interface address pools arenot on the same network segment, so the clients cannot communicate with each other.Therefore, in the interface address pool mode, if the DHCP clients in a VLAN need to obtain IPaddresses from the same network segment, the number of DHCP clients cannot exceed the number ofthe IP addresses assignable in the VLAN interface address pool.Configuration Task ListAn interface address pool is created when the interface is assigned a valid unicast IP address and youexecute the dhcp select interface command in interface view. The IP addresses contained in it belongto 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 interfaceswithin specified interface ranges. Configuring for multiple interfaces eases configuration work load andmakes you to configure in a more convenient way.Complete the following tasks to configure the interface address pool based DHCP server:Task RemarksEnabling the Interface Address Pool Mode on Interface(s) RequiredConfiguring the static IP addressallocation modeConfiguring anAddress AllocationMode for anInterface AddressPoolConfiguring the dynamic IP addressallocation modeOne of the two options is required.
