Source MAC address based ARP attack detection
configuration example
Network requirements
As shown in
, the hosts access the Internet through a gateway (Device). If malicious users send
a large number of ARP requests to the gateway, the gateway may crash and cannot process requests
from the clients. To solve this problem, configure source MAC address based ARP attack detection on the
gateway.
