Configure Optional DAI Features If you configure the source MAC address validation option, DAI verifies that the sender MAC address in an ARP packet equals the source MAC address in the Ethernet header. There is a configurable option to verify that the target MAC address in the ARP packet equals the destination MAC address in the Ethernet header. This check applies only to ARP responses, since the target MAC address is unspecified in ARP requests. You can also enable IP address checking. When this option is enabled, DAI drops ARP packets with an invalid IP address. The following IP addresses are considered invalid: • 0.0.0.0 • 255.255.255.255 • All IP multicast addresses • All class E addresses (240.0.0.0/4) • Loopback addresses (in the range 127.0.0.0/8) The valid IP check is applied only on the sender IP address in ARP packets. In ARP response packets, the check is applied only on the target IP address. Configure System Information 78
