To Specify the Device Instance for the

ndd

Utility

1. Check the

/etc/path_to_inst

file to identify the instance number associated

with a particular

SUNW,qfe

device.

For example:

In the preceding example, the four

SUNW,qfe@

instances are from a Sun Quad

FastEthernet 6U CompactPCI adapter. For clarity, the instance numbers are shown in
boldface type.

2. Use the

ndd

command to select the

SUNW,qfe

device using the instance number.

The device instance will remain selected until you change the selection.

Using the

ndd

Utility in Noninteractive and Interactive

Modes

You can use the

ndd

utility in two modes:

■

Noninteractive

■

Interactive

In the noninteractive mode, you can invoke the utility to set or display a single
device driver parameter. Once you execute the

ndd

command, the utility will exit

back to the terminal prompt. In the interactive mode, you can display or set more
than one driver parameter value using the utility’s prompt. Refer to the

ndd

(1M)

man page for more information about using the

ndd

utility.
