Description

This article describes how to share a physical interface between multiple VDOMs.

The requirements are:

• Management access to Global configuration.
• A physical interface from any VDOM connected to a L3 device in trunk mode.
• Use of VLAN interfaces for each VDOM.

Solution

1. Log into the FortiGate with an admin user with access to Global resources.
2. Go to Global settings -> Network -> Interfaces.
3. Select Create New -> Interfaces:

• The type of the interface must be VLAN.
• Select a physical interface from the Interface drop-down menu.  It can be any interface from any VDOM.
• Set a VLAN ID for this new VLAN.
• Under Virtual Domain, select the VDOM that will use this VLAN.

4. Select the '+' button next to the green arrow icon and the physical interface will show the newly created VLAN interfaces and their respective VDOMs.
