44 Sun PCI-Express Dual Gigabit Ethernet MMF/UTP Adapter Installation and User’s Guide • June 2006
The Sun PCI-Express Dual Gigabit Ethernet ExpressModule performs
autonegotiation with the remoteend of the link (the link partner) to select a common
mode of operation.
The Sun PCI-Express Dual Gigabit Ethernet ExpressModule also supports a non-
autonegotiated mode of operation. Youcan set the speed and mode using the ndd
utility,or, to make sure the changes persist after a system reboot, you can create a
e1000g.conf file. See “ToSet Driver Parameters Using the e1000g.conf File” on
page44 for more information about setting driver parameters.
The Sun PCI-ExpressDual Gigabit Ethernet UTP ExpressModule is capable of all the
operating speeds and modes listed in “Setting Parameters Using the ndd Utility” on
page47. The e1000g device performs autonegotiation with the remote end of the
link (link partner) to select a common mode of operation. The e1000g device also
supports Forced mode operation.
Setting e1000g Driver Parameters
Youcan set the e1000g device driver parameters using the e1000g.conf file
Toset parameters so they remain in effect after you reboot the system, create a
/kernel/drv/e1000g.conf file and add parameter values to this file when you
need to set a particular parameter for a device in the system.

▼To Set Driver Parameters Using the

e1000g.conf File
