Hello
has anyone setup a HA FGT (300D in my case) connected to 2 FSW while using Aggregated ports as Fortilink ports?
Whenever i use the interconnect between the Fortiswitches i create a loop - if i not use that ISL - i only see that one switch connected to the active firewall.
I may miss a point :)
I would appreciate any help as the manual is not very helpfull.
I am running 5.6 and 3.6.2 Firmware
Thanks!

Have you set the aggregate ports on the Fortigate you are using to split interface mode?
Commands as follows:
config system interface
edit "Whatever your interface aggregate is"
set fortilink-split-interface enable

Hi Mikt,
Yes, I did test the setup of a FG Cluster (active-Passive) connecting to 2 different fortiSwitches.
I did use an aggregate interface as a fortiLink & it worked fine.
Solution:
If a fortiGate/Cluster is connected to two different fortiSwitches via fortiLink, then your MUST use fortiLink-split-interface enabled command. The only exception is to use MCLAG and create an ICL between these fortiSwitches instead of using normal ISL. After that you can disable the fortiLink-split-interface command. ;)
Ref: Page 2142 of the FortiOS Handbook for FortiOS 5.6.2
The following topology was tested in my lab and it worked fine:
I hope it was helpful.
Thanks & regards,
Prab :)
