Rules for VLAN IDs

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 FortiGate network interfaces.

Transparent mode virtual domains and VLANs

VLAN subinterfaces are added to and associated with virtual domains. By default the FortiGate 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 131
