The Sun PCI-Express Dual Gigabit Ethernet adapter performs autonegotiation with
the remote end of the link (the link partner) to select a common mode of operation.
The Sun PCI-Express Dual Gigabit Ethernet ada[ter also supports a non-auto-
negotiated mode of operation. You can set the speed and mode using the
ndd
utility,
or, to make sure the changes persist after a system reboot, you can create a
ipge.conf
file. See “To Set Driver Parameters Using an
ipge.conf
File” on
page 27 for more information about setting driver parameters.
The Sun PCI-Express Dual Gigabit Ethernet UTP adapter is capable of all the
operating speeds and modes listed in
“Setting the Autonegotiation Mode” on
page 25 . The
ipge
device performs auto-negotiation with the remote end of the link
(link partner) to select a common mode of operation. The
ipge
device also supports
Forced mode operation.
Setting
ipge
Driver Parameters
You can set the
ipge device
driver parameters in two ways:
■
Using the
ndd
utility
■
Using the
ipge.conf
file
If you use the
ndd
utility, the parameters are valid only until you reboot the system.
This method is good for testing parameter settings.
To set parameters so they remain in effect after you reboot the system, create a
/kernel/drv/ipge.conf
file and add parameter values to this file when you need
to set a particular parameter for a device in the system.
Setting Parameters Using the
ndd
Utility
Use the
ndd
utility to configure parameters that are valid until you reboot the
system. The
ndd
utility supports any networking driver that implements the Data
Link Provider Interface (DLPI).
The following sections describe how you can use the
ipge
driver and the
ndd
utility
to modify (with the
-set
option) or display (without the
-set
option) the
parameters for each
ipge device
.
