To Specify Device Instances for the ndd Utility

Before you use the ndd utility to get or set a parameter for a ixge device, you must specify the device instance for the utility.

1.Check the /etc/path_to_inst file to identify the instance associated with a particular device.

#grep ixge /etc/path_to_inst "/pci@9,600000/ethernet@1" 0 "ixge"

In this example, the 10-Gigabit Ethernet instance is from the installed adapter. The instance number is in bold italics for clarity.

2.Use the instance number to select the device.

#ndd -set /dev/ixge instance number

The device remains selected until you change the selection.

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.
