SPARC: Sun Gigabit Ethernet Adapter Considerations

Some Gigabit Ethernet switches require some device parameter values to be set differently than the defaults. Chapter 3 of the Sun Gigabit Ethernet/P 2.0 Adapter Installation and User's Guide describes the procedure about how to change device parameters.

Chapter 3 of the Sun Gigabit Ethernet/P 2.0 Adapter Installation and User's Guide describes the procedure on how to change ge device parameter values. This change occurs through entries in the /kernel/drv/ge.conf file. The procedure to derive the parent name from the /etc/path_to_inst listing, which is be used in ge.conf entries, appears in Setting Driver Parameters Using a ge.conf File. For example, from the following /etc/path_to_inst line, you can derive the parent name for ge2 to be /pci@4,4000.

"/pci@4,4000/network@4" 2 "ge"

OnOracle Solaris Cluster nodes, a /node@nodeid prefix appears in the /etc/path_to_inst line. Do not consider the /node@nodeid prefix when you derive the parent name. For example, on a cluster node, an equivalent /etc/path_to_inst entry would be the following:

"/node@1/pci@4,4000/network@4" 2 "ge"

The parent name for ge2, to be used in the ge.conf file is still /pci@4,4000 in this instance.
