2.3.3 Configuring to Assign the IP Addresses of Interface Address Pools
to DHCP Clients
If the DHCP server works in the interface address pool mode, it picks IP addresses

available IP address in the interface address pools, the DHCP server picks IP
addresses from its global address pool that contains the interface address pool
segment and assigns them to the DHCP clients.
