DAI relies on DHCP snooping, which relies on DHCP message exchanges and builds a binding database of settings ({MAC address, IP address, VLAN, and interface}. When enabled, the MAC and sender IP addresses of ARP packets not matching entry in the DHCP snooping bindings database are dropped. 5-454 ip arp inspection vlan Enable Dynamic ARP Inspection on a list of comma-separated VLAN ranges.
