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
