Configuring Network Security
2) Configure IP-MAC Binding on Switch A. The binding entries for User 1 and User 2 will be
automatically learned via DHCP Snooping, and you need to manually bind the entry for
User 3.
3) Enable ARP Detection on Switch A to prevent ARP cheating attacks.
4) Configure ARP Defend on Switch A to limit the speed of receiving the legal ARP packets
on each port, thus to prevent ARP flooding attacks.
