Setting Driver Parameters

The eri device driver, which is loaded from the Solaris CD-ROM, controls the SUNW,eri Ethernet devices. The device driver selects the link speed using the auto-negotiation protocol with the link partner. Click on this link to the Appendix A, Appendix A, Auto-Negotiation, for further information.

You can manually set the eri device driver parameters to customize each SUNW,eri device in your system in one of three ways. Click on this link, Chapter 4, Setting Parameters, for more information on the ways you can customize your device.

To Force Network Speed Between 10 Mbps and 100 Mbps

1. At the ok prompt, use the show-devs command to list the system devices.

   You should see the full path names of the eri devices, similar to the following example:

   /pci@8,700000/network@5,1

2. Type:

   ok nvedit

3. Type the following, pressing the Return key at the end of line 0:

   0: probe-all install-console banner 1: apply transfer-speed=10 full_ path_name_of_a_eri_device

   ---

   Note -

   If you already have commands in NVRAM, append these lines to the end of the file.

   ---

4. Press Control-C after typing full_ path_name_of_a_eri_device.

   Perform Steps 2 to 4 to set the network speed for each eri network interface.

   ---

   Note -

   In the preceding example, the speed is forced to 10 Mbps. To force the speed to 100 Mbps, replace 10 with 100.

   ---

5. At the ok prompt type:

   ok nvstore ok setenv use-nvramrc? true

6. Reboot your system.

   See "Setting Forced Mode" for more information on forcing network speed.
