Oracle VM supports multiple virtual LANs, or VLANs, on the same network port or bond. Each VLAN is essentially an independent logical network operating with other VLANs over the same physical connection. This means that virtual machines deployed on different networks, connected through the same Oracle VM Server port (or bond), can have traffic directed to different VLANs. This feature is implemented using VLAN groups.

Configuring VLANs involves creating one or more VLAN Groups, each of which can house multiple VLANs. Each VLAN is assigned a distinct VLAN identification. The VLAN ID is used by an attached VLAN switch to segregate traffic among the different VLANs operating on the same link. When a VLAN is configured, it functions exactly like a separate physical connection.
