Chapter 5 Configuring the nxge Device Driver Parameters 35

▼ 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.

▼ 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 -set option.

If you invoke the ndd utility with the -set option, the utility passes value, which

must be specified, down to the named /dev/nxgedriver_instance, and assigns the

value to the parameter:

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 -set option, the utility queries the named driver instance,

retrieves the value associated with the specified parameter, and prints it:

▼ To Use the ndd Utility in Interactive Mode

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

# 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"

# ndd -set /dev/nxgeX parameter-value

# ndd /dev/nxgeX parameter

# ndd /dev/nxge0

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

parameters)
