Question

Convert VLAN to SD-WAN

Okay so long story short. We have a WAN interface with multiple VLANs running to different ISP. I figured it would be simple to just convert the VLAN interface to SD-WAN but no.

When labbing the change I found that if the interface type is physical I can not integrate the interface to SD-WAN and also I am not able to do it via the SD-WAN GUI by adding members and also not via CLI. The VLAN interface doesn’t show up.

When the interface is set to type aggregate then I am able to change the VLAN interface to SD-WAN interface.

Running 7.2.11 - is there something I am missing here? This feels so stupid.

Hi!

You can add the VLAN's to the SD-WAN as members as long as it has no references.
It would also be worth a try to "Migrate" the interface which you can do so by following these steps: https://community.fortinet.com/t5/FortiGate/Technical-Tip-Moving-an-Interface-that-has-existing-references/ta-p/301238
