You cannot set "DHCP reservations using the Aruba controller. You will have to use an external DHCP server if you want to do this. The other "so-so" alternative is to create a DHCP exclusion using the Aruba controller and give the client a static ip address. You could also create a long lease time so a client gets the same ip address.
The Aruba built-in DHCP server is typically used for guest access and does not have all the features of an enterprise DHCP server.
