▼To Specify Device Instances for the ndd Utility

Before you use the ndd utility to get or set a parameter for a nxge 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 nxge /etc/path_to_inst "/pci@7c0/pci@0/pci@9/network@0" 0 "nxge" "/pci@7c0/pci@0/pci@9/network@0,1" 1 "nxge"

▼To Specify Parameter Values Using the ndd Utility

This section describes how to modify and display parameter values.

1.To modify a parameter value, use the -setoption.

If you invoke the ndd utility with the -setoption, the utility passes value, which must be specified, down to the named /dev/nxgedriver_instance, and assigns the value to the parameter:

#ndd -set /dev/nxgeXparameter-value

Where X is the driver instance, for example /dev/nxge0, /dev/nxge1.

2.To display the value of a parameter, specify the parameter name and omit the value.

When you omit the -setoption, the utility queries the named driver instance, retrieves the value associated with the specified parameter, and prints it:

#ndd /dev/nxgeX parameter

▼To Use the ndd Utility in Interactive Mode

1.To modify a parameter value in interactive mode, specify ndd /dev/nxgeX:

#ndd /dev/nxge0

name to get/set? (Enter the parameter name or ? to view all parameters)
