Setting
nxge
Driver Parameters on a
Solaris Platform
You can set the
nxge
device driver parameters in two ways:
■
Using the
ndd
utility
■
Using the
nxge.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
/platform/sun4u/kernel/drv/nxge.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 following sections describe how you can use the
nxge
driver and the
ndd
utility
to modify (with the
-set
option) or display (without the
-set
option) the
parameters for each
nxge
device.
Noninteractive and Interactive Modes
You can use the
ndd
utility in two modes:
■
Noninteractive
■
Interactive
In noninteractive mode, you invoke the utility to execute a specific command. Once
the command is executed, you exit the utility. In interactive mode, you can use the
utility to get or set more than one parameter value. Refer to the
ndd
(1M) man page
for more information.
