Prevent ARP Spoofing via Packet Content ACL 

D-Link managed switches can effectively mitigate common DoS attacks caused by ARP spoofing via a unique Package Content 
ACL. 

For the reason that basic ACL can only filter ARP packets based on packet type, VLAN ID, Source, and Destination MAC 
information, there is a need for further inspections of ARP packets. To prevent ARP spoofing attack, we will demonstrate here via 
using Packet Content ACL on the Switch to block the invalid ARP packets which contain faked gateway’s MAC and IP binding. 

 

Example topology
