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 > 

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.
