I've got 2 FSW 248d connected via fortilink to FWF60. Fortilink is setup on 2 ports set as Hardware switch. To this hardware switch i've setup a number of vlans. On version 6.2 FortiOS i can setup forti link on 2 ports running as aggregate. My question is: Is there a way to change interface type "Hardware switch" to aggregate, without loosing vlan config?
