Dynamic ARP Inspection
Dynamic ARP inspection (DAI) is a security feature that rejects invalid and malicious ARP
packets. The feature prevents a class of man-in-the-middle attacks, where an unfriendly
station intercepts traffic for other stations by poisoning the ARP caches of its unsuspecting
neighbors. The miscreant sends ARP requests or responses mapping another station’s IP
address to its own MAC address.
