FortiLink with cascade of FortiSwitch

Hi all,


do you know if it's possible a configuration like this:


FORTIGATE ----fortilink------ FORTISWITCH1 -----fortilink----- FORTISWITCH2


From the FortiGate I'm able to view the first FortiSwitch but not the second one...

Yes it should work in the latest FortiOS 5.4.1 and FortiSwitch 3.4.2.

Look in the documents at


FortiGate 200A/B, 224B, 110C, 100A/D, 80C/CM/Voice, 60B/C/CX/D, 50B, 40C, 30B
FortiAnalyzer 100B, 100C
FortiMail 100,100C
FortiManager VM
FortiAuthenticator VM
FortiAP 220B/221B, 11C

I haven't found specific documents related to the solution I'd like to apply and as a first try I was not able to "view" the second switch via FortiLink but only the "first" one (the one directly connected to the FortiGate).


Forgive my use of the english language on the second paragraph :D


FortiOS 5.4.1 requires you to have only one FortiSwitch connected to the FortiGate. The rest of the switches will do FortiLink off of that one.


Oh yeah, depending on the port you have connected, you might have to manually (CLI) enable FortiLink on your uplink port. I think the 448D has FortiLink enabled by default only on the fiber ports.


Never set up one on a multi-vdom FG.

I have implemented Fortigate (HA)--Fortlink--Fortiswitch----other Fortiswitches which seems to be working but all on one VDOM.

Haven't been able to find any documentation on implementation this on multiple VDOMs. In the past I have used cisco switches(nexus, IOS) for this implementation, where the aggregate is set up on say root VDOM and VLAN interfaces are setup on the different vdoms but using the same trunk port set up on root as the interface to the switches(Works great). I have not been able to mimic this with the fortiswitches.

Thanks for your comments in advance.
