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

# 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/nxge X parameter-value
# ndd /dev/nxge X parameter
# ndd /dev/nxge0
