Configuring the FortiLink interface

FortiLink connects switches (and APs) directly to FortiGate so that the network acts as a single device.

To configure the FortiLink interface:

1. Go to Network > Interfaces, and double-click fortilink to open the interface for editing.
2. Review the Interface members option. Do you see two members or no members?

   Take one of the following actions:

   • If you see two members, FortiLink is ready to connect to a switch. Note the port labels for the two members. The ports are likely labeled A and B, if they exist on your physical FortiGate.
   • If you see no interface members, select the two physical LAN ports that were removed in the previous section. See Removing ports from the LAN hardware switch interface.
3. Set the following settings in the Address section:
   1. Set Address mode to Dedicated to FortiSwitch.
   2. Enable Automatically authorize devices.

      Devices can be manually admitted one at a time later if you wish.

   3. Disable FortiLink split interface. The split interface is used in scenarios where two or more switches are connected directly to a FortiGate.
4. Enable DCHP server. The connected FortiSwitch will receive an IP address in this range.
5. Click OK to save the FortiLink settings.
