Configuring the nxge Device Driver Parameters


▼ 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


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


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