Configuring Driver Parameters

The qfe device driver, which is loaded from the CD-ROM, controls the SUNW,qfe Ethernet devices. The device driver automatically selects the link speed using the auto-negotiation protocol with the link partner (see "Auto-Negotiation").

You can manually configure the qfe device driver parameters to customize each SUNW,qfe device in your system in one of three ways:

• Configure the qfe driver parameters generally for all SUNW,qfe devices in the system by entering the parameter variables in the /etc/system file.

• Set a parameter on a per-device basis by creating the qfe.conf file in the /kernel/drv directory.

• Use the ndd utility to temporarily change a parameter. This change is lost when you reboot the system.

See Appendix C, Configuring the Quad FastEthernet Device Driver Parameters" for more information.
