Sun Quad FastEthernet SBus Adapter Installation and User's Guide

Setting Parameters in the /etc/system File

To configure the qfe driver parameters for all SUNW,qfe devices in the system so that the parameter variables are always effective (even after rebooting the system), enter the parameter variables in the /etc/system file. When you reboot the system, the system reads the /etc/system file and sets these parameter variables in the qfe module in the operating system kernel.

Table C-9 lists the variables you can set in the /etc/system file.

These parameter values, described in "Driver Parameter Values and Definitions", are applicable to all SUNW,qfe devices on the system. See Table C-1 through Table C-8 for the descriptions of these parameters.

Here's an example of setting parameters in a /etc/system file:

Setting the ipg1 and ipg2 Parameters in the /etc/system File

  1. Become superuser.

  2. Add the following lines to the /etc/system file: 

    set qfe:qfe_ipg1 = 10
set qfe:qfe_ipg2 = 5

  3. Save the /etc/system file.

  4. Save all files and exit all programs, then exit the windowing system.

  5. Reboot the system by typing init 6 at the superuser prompt.
