ARP sent the request in broadcast, response is unicast

When a source sends arp request the switch broadcast the arp req. if it doesn't hav d destination mac address in its mac address table, if the destination mac is known then switch simply forwards the request to that particular host and the host sends the arp response to the switch and the switch will further send the arp response to the source requesting the mac address.
