Configuring Driver Parameters

Setting

Driver Parameters

You can set the

device driver parameters in two ways:

■

Using the

ndd

utility

■

Using the

ce.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/ce.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, which implements the Data

Link Provider Interface (DLPI).

The following sections describe how you can use the

driver and the

ndd

utility to

modify (with the

-set

option) or display (without the

-set

option) the parameters

for each

device.
