Use this screen to look at the current list of MAC address filters that were created

identifies an unauthorized ARP packet, it automatically creates a MAC address
filter to block traffic from the source MAC address and source VLAN ID of the
unauthorized ARP packet. To open this screen, click Advanced Application > IP
Source Guard > ARP Inspection.
