This enhancement is new in the Solaris Express 6/05 release and in the Solaris 10 1/06 release.
The Solaris OS now contains features that extend the configuration possibilities for the bge and xge network interfaces. System administrators can now group these interfaces into LACP-capable link aggregations. These aggregations can support large-scale high availability or database implementations. In addition, you can configure xge and bge interfaces into virtual local area networks (VLANs) to extend network capability.
The new dladm command has been added for configuring and administering bge and xge interfaces. For further information, refer to the dladm(1M) man page.
