4.12.12 ARP Inspection

ARP Inspection 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 proviFigure 4-12-12
