To Specify the Device Instance for the ndd Utility

Before you use the ndd utility to get or set a parameter for a ge 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.

For Sun GigabitEthernet/P:

#grep ge /etc/path_to_inst “/pci@4,4000/network@4” 2 “ge” “/pci@6,2000/network@1” 1 “ge” “/pci@4,2000/network@1” 0 “ge”

In this example, the three GigabitEthernet instances are from the adapters installed in perspective PCI slots.

For Sun GigabitEthernet/S:

#grep ge /etc/path_to_inst “/sbus@b,0/network@2,100000” 0 “ge”

In this example, the GigabitEthernet instance is from an adapter installed in a perspective SBus slot.

2.Use the instance number to select the device.

#ndd -set /dev/ge instance instance_number

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.)
