To set parameters so they remain in effect after you reboot the system:
•
Add the parameter values to
/etc/system
when you want to configure
parameters for all devices in the system.
•
Create the
hme.conf
file and add parameter values to
hme.conf
when you
need to set a particular parameter for a device in the system.
If you want to test parameter settings, use the
ndd
utility described in Chapter
3. With
ndd,
the parameters are effective until you reboot the system. To
make the parameter settings permanent, enter the values in
/etc/system
or
hme.conf
as described in this chapter.
Setting Parameters Using
ndd
Use the
ndd
utility to configure parameters that are valid until you reboot the
system. The
ndd
utility supports any networking driver, which implements the
Data Link Provider Interface (DLPI).
The following sections describe how you can use the
hme
driver and the
ndd
utility to modify (with the
-set
option) or display (without the
-set
option)
the parameters for each
SUNW,hme
device.
Identifying Device Instances
Before you use the
ndd
utility to get or set a parameter for the
hme
device, you
must specify the device instance for the utility if there is more than one
SUNW,hme
device.
Note – If there is only one
SUNW,hme
device, the device is automatically
chosen by the
ndd
utility.

To specify the device instance for the
ndd
utility
1. Check the
/etc/path_to_inst
file to identify the instance associated
with a particular device.
