To Specify the Device Instance for the
ndd
Utility
1. Check the
/etc/path_to_inst
file to identify the instance associated with a
particular device.
In the example above, the four
SUNW,qfe@
x
,1
instances are from a Sun Quad
FastEthernet PCI adapter installed in slot 2. For clarity, the instance numbers are
bold.
2. Use the instance number to select the device.
The device remains selected until you change the selection.
Non-Interactive and Interactive Modes
You can use the
ndd
utility in two modes:
■
Non-interactive
■
Interactive
In non-interactive 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.)
