How to stop unknown unicast from LAN to be flooded by the controller to WLAN

By default behavior of switching the unknown unicast is flooded across. On Aruba controller we could stop the unknown unicast coming from the LAN to be flooded, by enabling the BC/MC optimization on the VLAN interface

(config) #interface vlan < VLAN ID > 
(config-subif)#bcmc-optimization

Before enabling BC/MC optimization please read below

BC-MC Optimization (VLAN Knob): This will drop all the broadcast and multicast frames on a VLAN (both wired and wireless interfaces) except for ARP, DHCP, IPv6 router advertisement, IPv6 neighbor solicitation and VRRP traffic.
