Sun Microsystems 220R manual Determining the Device Name of the Ethernet Interface, Solution

Note –Some hub designs permanently enable (or disable) the link integrity test through a hardware jumper. In this case, refer to the hub installation or user manual for details of how the test is implemented.

Determining the Device Name of the Ethernet Interface

To enable or disable the link integrity test for the standard Ethernet interface, or for a PCI-based Ethernet interface, you must first know the device name of the desired Ethernet interface. To list the device name use either solution described below.

Solution 1

Use this method while the operating system is running:

1.Become superuser.

2.Type:

#eeprom nvramrc=”probe-all install-console banner apply disable-link-pulse device-name”

(Repeat for any additional device names.)

#eeprom “use-nvramrc?”=true

3.Reboot the system to make the changes effective.

Solution 2

Use this alternate method when the system is already at the OpenBoot prompt:

1.Shut down the operating system and take the system to the ok prompt.

2.Determine the device name for the desired Ethernet interface.

3.At the ok prompt, type:

ok nvedit

0:probe-all install-console banner

1:apply disable-link-pulse device-name

(Repeat this step for other device names as needed.) (Press CONTROL-C to exit nvedit.)

ok nvstore

ok setenv use-nvramrc? true

4. Reboot the system to make the changes effective.
