Dynamic ARP Inspection

malicious ARP packets. DAI 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 malicious attacker send ARP requests or responses mapping

another station’s IP address to its own MAC address.

When DAI is enabled, the switch drops ARP packets whose sender MAC address and

sender IP address do not match an entry in the DHCP snooping bindings database. You can

optionally configure additional ARP packet validation. When DAI is enabled on a VLAN, DAI

is enabled on the interfaces (physical ports or LAGs) that are members of that VLAN.

Individual interfaces are configured as trusted or untrusted. The trust configuration for DAI is

independent of the trust configuration for DHCP snooping.

The Dynamic ARP Inspection (DAI) folder contains links to the following features:
