Fortigate vxlan cannot add system vlan interface to switch

[mAineAc]

I have two 80F fortigates that i am trying to lab vxlan on for production. One system is on 7.2.4 and the other is on 7.2.2. Following the documentation it says to add the vlan interface and the vxlan interface to the switch for the last step. On the 7.2.2 version it has the vlan system interfaces available to add to the switch. These are identical configs on each side I have them set up as policy based and vlan switch mnode. Not sure if this is a bug, but I am using this guide to set up the vxlan

So I upgraded the device on version 7.2.2 to see if that makes a difference and it did not. I still only have the options for the vlan interfaces and not the physical interfaces to be able to add for the system switch--interface. I also tried deleting and recreating the vlan interfaces on the one that was originally on 7.2.4 but that did not make a difference either.

I think it's a mistake in the guide and a virtual-wire-pair is created, because in a software-switch you can add only physical interfaces,

config system switch-interface

  edit TEST

  set member
     *interface-name Physical interface name.

This is the config in one:

LAB-17 # show system switch-interface
config system switch-interface
edit "OES-SW1"
set vdom "root"
set member "vlan253" "vxlan253"
next
end

LAB-17 #

and I do not have the option to add the physical interfaces

On the other system it lets me add the vxlan interface but the internal6 is no longer available after removing

LAB-16 # conf system switch-interface

LAB-16 (switch-interface) # edit OES-SW1

LAB-16 (OES-SW1) # set member
*interface-name Physical interface name.
OES-ME-VXLAN interface
internal5 interface

LAB-16 (OES-SW1) # set member

Check if the interface that you try to add is referenced on other part of the configuration. If the interface is use on other things like in a firewall rule, if it have and ip or a address object attached to the interface it will not be available to add to the softswitch.
