FG 100F fortilink ports

Hello,

I have just received a new FG 100F and noticed that there are 2 x 10G fortilink ports.

From the datasheet, it said they are used to connect into Fortiswitch.

Does the Fortilink protocol work only between Forti devices? Can I use them to connect to other constructor devices?

If I reconfigure them to regular ports, can I configure them as LACP ports?

Thank you very much.
