In an Oracle Solaris 10 logical domains environment, the virtual switch service running in a service domain can directly interact with GLDv3-compliant network adapters. Though non-GLDv3 compliant network adapters can be used in these systems, the virtual switch cannot interface with them directly. See Configuring a Virtual Switch and the Service Domain for NAT and Routing for information about how to use non-GLDv3 compliant network adapters.
