Use the dladm rename-link command to rename a datalink. On an Oracle Solaris system, the OS automatically provides generic names to all datalinks. For more information about generic datalink names, see About Datalink Configuration.
By default, these generic names use the naming format netn, such as net0, net1, net2, and so on. Because the OS manages these names, you would not rename datalinks as a regular part of your administrative tasks. For a procedure that requires changing link names, see How to Move IP Configuration From One Network Device to Another Device.
