Chapter 17 System Administration : VLANs : VLANs in transparent mode : VLANs and transparent mode : Add VLAN subinterfaces
  
Add VLAN subinterfaces
The VLAN ID of each VLAN subinterface must match the VLAN ID added by the IEEE 802.1Q-compliant router or switch. The VLAN ID can be any number between 1 and 4094, with 0 being used only for high priority frames and 4095 being reserved. You add VLAN subinterfaces to the physical interface that receives VLAN-tagged packets.
For this example, we are creating a VLAN called internal_v225 on the internal interface, with a VLAN ID of 225. Administrative access is enabled for HTTPS and SSH. VDOMs are not enabled.
To add VLAN subinterfaces in transparent mode - web-based manager
1. Go to System > Network > Interface.
2. Select Create New.
3. Enter the following information and select OK.
Name
internal_v225
Type
VLAN
Interface
internal
VLAN ID
225
Administrative Access
Enable HTTPS, and SSH. These are very secure access methods.
Comments
VLAN 225 on internal interface
The FortiGate unit adds the new subinterface to the interface that you selected.
Repeat steps 2 and 3 to add additional VLANs. You will need to change the VLAN ID, Name, and possibly Interface when adding additional VLANs.
To add VLAN subinterfaces in transparent mode - CLI
config system interface
edit internal_v225
set interface internal
set vlanid 225
set allowaccess HTTPS SSH
set description “VLAN 225 on internal interface”
set vdom root
end
