Description This article describes how to use the hardware switch to manage the FortiSwitches. 
Scope All FortiOS.
Solution

Enable the FortiLink option from the CLI.

 

config system interface

FGT(interface) # edit Hardware_Switch

FGT(Hardware_Switch) # set fortilink enable

FGT(Hardware_Switch) # end

 

The difference will be visible, once the option has been enabled through the CLI.

The benefit of using hardware switch instead of link aggregate to manage switches is that in an HA active-passive cluster, the FortiSwitches can be connected in a cascading manner without MC-LAG config.
