Solution
Using the FortiGate CLI.
For IPv4:
config system arp-table
edit %value%
set interface <interface-name>
set IP
set mac
end
set interface <interface-name>
set IP
set mac
end
For example:
config system arp-table
edit 1
set interface internal
set ip 192.168.1.50
set mac 00:50:5A:20:14:1E
end
set interface internal
set ip 192.168.1.50
set mac 00:50:5A:20:14:1E
end
For IPv6:
diagnose ipv6 neighbor-cache add <interface-name> <ipv6 address> <mac-address>
For example:
