2 Platform Notes: The Sun GigabitEthernet Device Driver • March 1999 2. Use the prtconf -pv command to determine if the system already contains a GigabitEthernet ( ge ) device. For Sun GigabitEthernet/S: For Sun GigabitEthernet/P: 3. Install the software. ■ If your system contains a ge device, insta...

Installing and Configuring the ge Device Driver 3 2. Use the grep command to search the /etc/path_to_inst file for ge instances. For Sun GigabitEthernet/P: For Sun GigabitEthernet/S: In these examples, the 0 instance is for the first GigabitEthernet adapter installed in each system. 3. Set up each h...

4 Platform Notes: The Sun GigabitEthernet Device Driver • March 1999 Configuring the Driver Parameters This section provides an overview of the capabilities of the GigabitEthernet ASICused in the adapters, lists the available ge driver parameters, and describes how to configure these parameters. The...

Installing and Configuring the ge Device Driver 5 Driver Parameter Values and Definitions TABLE 1 describes the parameters and settings for the ge driver. TABLE 1 ge Driver Parameters, Status, and Descriptions Parameter Status Description link_status Read only Defines the current status link_speed R...

6 Platform Notes: The Sun GigabitEthernet Device Driver • March 1999 Defining the Current Status The read-only parameters described in TABLE 2 explain the operational mode of the interface. Based on the value of these parameters, you can determine the currentstatus of a link. Flow Control Parameters...

Installing and Configuring the ge Device Driver 7 Interpacket Gap Parameters The GEM ASIC supports the programmable Interpacket Gap (IPG) parameters ipg1 and ipg2 . The total IPG is the sum of ipg1 and ipg2 : 0.096 microseconds for the link speed of 1000 Mbps. TABLE 4 lists the default values and al...

Installing and Configuring the ge Device Driver 9 Reporting Local PCS Capabilities TABLE 7 describes the read-only PCS capabilities that GEM PCS supports. These parameters define the capabilities of the hardware. Reporting the Link Partner Capabilities TABLE 8 describes the read-only link partner ca...

10 Platform Notes: The Sun GigabitEthernet Device Driver • March 1999 If the link partner is not capable of autonegotiation (when lp_1000autoneg_cap is 0) the remaining information described in TABLE 8 is not relevant and the parameter value = 0. If the link partner is capable of autonegotiation (wh...

Installing and Configuring the ge Device Driver 11 ▼ To Specify the Device Instance for the ndd Utility Before you use the ndd utility to get or set a parameter for a ge device, you must specify the device instance for the utility. 1. Check the /etc/path_to_inst file to identify the instance associa...

12 Platform Notes: The Sun GigabitEthernet Device Driver • March 1999 ▼ To Use the ndd Utility in Non-Interactive Mode This section describes how to modify and to display parameter values. 1. To modify a parameter value, use the -set option. If you invoke the ndd utility with the -set option, the ut...

Installing and Configuring the ge Device Driver 13 ● To list all the parameters supported by the ge driver, type ndd /dev/ge \? . (See TABLE 1 through TABLE 8 for parameter descriptions.) Autonegotiation Mode By default, autonegotiation is set to on . This means that the adapter will communicate wit...

14 Platform Notes: The Sun GigabitEthernet Device Driver • March 1999 2. Set adv_1000autoneg_cap to 0 . Setting Parameters Using the ge.conf File You can also specify the properties described in this section on a per-device basis bycreating a ge.conf file in the /kernel/drv directory. Use a ge.conf ...

Installing and Configuring the ge Device Driver 15 Note – The “name” property in the ge.conf file should be the same value as the “compatible” property. In this case, the value is SUNW,sbus-gem . See page 7 for more information about the .properties file. For Sun GigabitEthernet/P: To identify a PCI...

16 Platform Notes: The Sun GigabitEthernet Device Driver • March 1999 ▼ To Set Parameters Using the ge.conf File on a PCI adapter 1. Set the ipg1 and ipg2 parameters for the above devices in the kernel/drv/ge.conf file. 2. Save the ge.conf file. 3. Save and close all files and programs, and exit the...

18 Platform Notes: The Sun GigabitEthernet Device Driver • March 1999 3. Create an appropriate entry in the /etc/hosts file for each active ge interface. For example: 4. If your system does not support Dynamic Reconfiguration (DR), reboot. ▼ To Set Up a Diskless Client on a Server You can set up a s...
