Preventing ARP Attacks
Use the ARP Attack Protection page to specify how to protect your network
against common types of ARP attacks and configure the IP&MAC binding rules.
IP&MAC Binding allows you to bind an IP address to a MAC address and vice
versa. It only allows traffic when the host IP address matches a specified MAC
address. By requiring the gateway to validate the source traffic’s IP address with
the unique MAC address of device, this ensures that traffic from the specified IP
address is not spoofed.
To prevent ARP attacks and configure the IP&MAC binding settings:
STEP 1
