Platform Notes: The hme FastEthernet Device Driver

Setting Parameters in the /etc/system File

To configure the hme driver parameters for all SUNW,hme 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 hme module in the operating system kernel.

Table 4-1 lists the variables you need to set in the /etc/system file.

These parameter values, described in Chapter 3, Parameter Definitions, are applicable to all SUNW,hme devices on the system. See Table 3-2 through Table 3-8 for parameter descriptions. An example follows.

To Set the ipg1 to 10 and ipg2 to 5 When Rebooting

  1. Become superuser.

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

    set hme:hme_ipg1 = 10
set hme:hme_ipg2 = 5

  3. Save the /etc/system file.

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

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

    The system is halted and then rebooted.
