Configuring source MAC address based ARP
attack detection
Introduction
With this feature enabled, the device checks the source MAC address of ARP packets delivered to the
CPU. It detects an attack when one MAC address sends more ARP packets in five seconds than the
specified threshold. The device adds the MAC address to the attack detection table.
Before the attack detection entry is aged out, the device uses either of the following detection modes to
respond to the detected attack:
• Monitor mode: Generates a log message.
• Filter mode: Generates a log message and filters out subsequent ARP packets from the attacking
MAC address.
You can also configure protected MAC addresses to exclude a gateway or server from detection. A
protected MAC address is excluded from ARP attack detection even if it is an attacker.
