A virtual interface is required for Layer 3 (IP) access to a controller, service platform, or virtual platform, or to provide Layer 3 service on a VLAN. The virtual interface defines which IP address is associated with each VLAN ID to which the device is connected. A virtual interface is created for the default VLAN (VLAN 1) to enable remote administration. A virtual interface is also used to map VLANs to IP address ranges. This mapping determines the destination for routing.
