The virtual switch (vsw) is a layer-2 switch, that also can be used as a network device in the service domain. The virtual switch can be configured to act only as a switch between the virtual network (vnet) devices in the various logical domains but with no connectivity to a network outside the box through a physical device. In this mode, creating the vsw as a network device and enabling IP routing in the service domain enables virtual networks to communicate outside the box using the service domain as a router. This mode of operation is very essential to provide external connectivity to the domains when the physical network adapter is not GLDv3-compliant.
The advantages of this configuration are:
The virtual switch does not need to use a physical device directly and can provide external connectivity even when the underlying device is not GLDv3-compliant.
The configuration can take advantage of the IP routing and filtering capabilities of the Oracle Solaris OS.

If assigning an address, ensure that the virtual switch has an unique MAC address.

See Configure the Virtual Switch as the Primary Interface for more information about creating the virtual switch.
See Configure the Virtual Switch as the Primary Interface for more information about configuring the virtual switch device for DHCP.
