Transparent mode
In Transparent mode two VLAN subinterfaces added to the same physical interface
cannot have the same VLAN ID. However, you can add two or more VLAN
subinterfaces with the same VLAN IDs to different physical interfaces. There is no
internal connection or link between two VLAN subinterfaces with same VLAN ID. Their
relationship is the same as the relationship between any two FortiWiFi network
interfaces.
VLAN subinterfaces are added to and associated with virtual domains. By default the
FortiWiFi configuration includes one virtual domain, named root, and you can add as
many VLAN subinterfaces as you require to this virtual domain.
You can add more virtual domains if you want to separate groups of VLAN
subinterfaces into virtual domains. For information on adding and configuring virtual
domains, see "System virtual domain" on page 137
