For ARP Guard, use this procedure to apply an ARP ACL to an interface or port-channel.
device# configure terminal
device(conf)# interface ethernet 1/2
device(conf-if-eth-1/2)# switchport
device(conf-if-eth-1/2)# ip arp inspection filter ARP_ACL_01
device(conf-if-eth-1/2)# exit device(conf)#
device# configure terminal device(conf)# interface ethernet 1/2 device(conf-if-eth-1/2)# switchport device(conf-if-eth-1/2)# ip arp inspection filter ARP_ACL_01 device(conf-if-eth-1/2)# exit
