Checking Parameter Settings; To Temporarily Change A Parameter; Increasing Tcp/Ip Performance - Sun Microsystems GigabitEthernet PCI Adapter User Manual

Checking Parameter Settings

To check a current parameter setting, use the following command:
# ndd /dev/vge

To Temporarily Change a Parameter

1. Check the /etc/path_to_inst file for the instance associated with particular
devices.
2. Specify the instance for the adapter you wish to configure:
# ndd -set instance
Any subsequent ndd configuration commands will act on the adapter with the
selected instance. The adapter remains selected until you specify a different instance.
3. Specify the configuration command using the following format:
<parameter> <value>
# ndd -set
Note – Any changes made with ndd will be lost when you reboot the system. To
make configuration changes survive the reboot process, you will need to store driver
settings in the /etc/rc2.d file (see "Saving Driver Parameters Beyond Reboot" on
page 15).

Increasing TCP/IP Performance

You can increase the TCP/IP performance of the Sun GigabitEthernet PCI Adapter
by changing the TCP/IP ndd values as follows:
<parameter_name>
<instance number>
