Description
Use the arp anti-attack valid-check enable command to enable ARP packet source MAC address
consistency check on the gateway. After you execute this command, the gateway device can filter out
ARP packets with the source MAC address in the Ethernet header different from the sender MAC address
in the ARP message.
Use the undo arp anti-attack valid-check enable command to restore the default.
By default, ARP packet source MAC address consistency check is disabled.
