Description
Use the arp anti-attack source-mac threshold command to configure the threshold for source MAC
address based ARP attack detection. If the number of ARP packets sent from a MAC address within five
seconds exceeds this threshold, the device considers this an attack.

By default, the threshold for source MAC address based ARP attack detection is 50.
