Using the
ndd
Utility in Noninteractive Mode
This section describes how to modify a parameter value and how to display a
parameter value using the
ndd
utility in noninteractive mode.
●
To modify a parameter value, use the

●
To display the value of a parameter, specify the parameter name, omitting the
-set
option.
When you omit the
-set
option (and omit the parameter value), the utility assumes
that you want to display the current parameter value.
For example, if you wanted view the link speed of the device, you would type:
In the preceding example, the link speed is set to 100 Mbps.
# ndd -set /dev/qfe
parameter value
# ndd -set /dev/qfe lance_mode 0
# ndd /dev/qfe
parameter
# ndd /dev/qfe link_speed
