Installing and Configuring the ge Device Driver 11
▼ 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:
In this example, the three GigabitEthernet instances are from the adapters installed
in perspective PCI slots.
For Sun GigabitEthernet/S:
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.
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.)
