Setting Parameters Using the nxge.conf File

Specify the driver parameter properties for each device by creating a nxge.conf file in the /kernel/drv directory. Use a nxge.conf file when you need to set a particular parameter for a device in the system.

The man pages for prtconf(1M) and driver.conf(4) include additional details. The next procedure shows an example of setting parameters in a nxge.conf file.

To access any man page, type the man command plus the name of the man page. For example, to access man pages for prtconf(1M), type:

%man prtconf
