Caution - This section only applies to the Oracle Solaris 10 system. Do not configure the vsw interface on the Oracle Solaris 11 system.
By default, networking between the control domain and other domains in the system is disabled. To enable this, the virtual switch device should be configured as a network device. The virtual switch can either replace the underlying physical device (nxge0 in this example) as the primary interface or be configured as an additional network interface in the domain.
Guest domains can automatically communicate with the control domain or service domain as long as the corresponding network back-end device is configured in the same virtual LAN or virtual network.
Note - Perform the following procedure from the control domain's console, as the procedure could temporarily disrupt network connectivity to the domain.
Note - If necessary, you can configure the virtual switch as well as the physical network device. In this case, create the virtual switch as in Step 2, and do not delete the physical device (skip Step 3). You must then configure the virtual switch with either a static IP address or a dynamic IP address. You can obtain a dynamic IP address from a DHCP server. For additional information and an example of this case, see Configuring a Virtual Switch and the Service Domain for NAT and Routing.
