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.

Interfaces do not appear in the sdwan member device selection if they are in use by e.g. a policy. So I'd suggest to check the references on the interfaces. Routing and VPN References are not relevant here. Those can coexist.

Basicially sdwan member can be a vlan as well as a physical interface.

I here at our site have a mixture of physical and vlan interfaces running as sdwan members...
