To set parameters so they remain in effect after you reboot the system, create a
/platform/sun4u/kernel/drv/ce.conf file and add parameter values to this
file when you need to set a particular parameter for a device in the system.
Setting Parameters Using the ndd Utility
Use the ndd utility to configure parameters that are valid until you reboot the
system. The ndd utility supports any networking driver that implements the Data
Link Provider Interface (DLPI).
The following sections describe how you can use the ce driver and the ndd utility to
modify (with the -set option) or display (without the -set option) the parameters
for each ce device.
To Specify Device Instances for the ndd Utility
Before you use the ndd utility to get or set a parameter for a ce 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 ce /etc/path_to_inst
"/pci@8,600000/network@1" 0 "ce"
In this example, the Gigabit Ethernet instance is from the installed adapter. The
instance number is in bold italics for clarity.
2. Use the instance number to select the device.
# ndd -set /dev/ce-instance-number
The device remains selected until you change the selection.
Noninteractive and Interactive Modes
You can use the ndd utility in two modes:
