Hi! If you have a table con the controller with some records ip -- mac addr you can intercept broadcast arp request with the packet in message and answer with a unicast packet out to the machine witch generated the request (arp reply)
Of course you COULD install a flowmod on the switch but it would be unusefull because arp request anyway would change every time, host by host. Anyway usually on the controller topology and device manager modules should help you ;) Luca P.
