Neighbor Discovery (ND) Attack Defense
ND Attack Defense is the equivalent of ARP Attack defense but using IPv6 addresses.
Navigate to Web UI → Security → ND Attack Defense page, then you can enable this security feature by clicking on "Source
MAC Consistency Check for ND Messages", now the device will check for Source MAC addresses to avoid any spoofing.
There is also the option to log these events by checking "Log" option.
