4.9.4 Dynamic ARP Inspection
Dynamic ARP Inspection (DAI) is a secure feature. Several types of attacks can be launched against a host or devices
connected to Layer 2 networks by "poisoning" the ARP caches. This feature is used to block such attacks. Only valid ARP
requests and responses can go through DUT. This page provides ARP Inspection related configuration.
A Dynamic ARP prevents the untrusted ARP packets based on the DHCP Snooping Database.
