Page 5: Installing And Configuring The Ge Device Driver
Installing and Configuring the ge Device Driver These Platform Notes include instructions for installing and configuring the software used by the Sun GigabitEthernet adapter. It also contains information for configuring the network. Unless otherwise noted, all instructions apply to both the Sun GigabitEthernet/P adapter and the Sun GigabitEthernet/S adapter. -

2. Use the prtconf -pv command to determine if the system already contains a GigabitEthernet (ge) device. For Sun GigabitEthernet/S: # prtconf -pv | grep SUNW,sbus-gem compatible: ’SUNW,sbus-gem’ model: ’SUNW,sbus-gem’ For Sun GigabitEthernet/P: # prtconf -pv | grep SUNW,pci-gem model: ’SUNW,pci-gem’ 3. - Page 7 2. Use the grep command to search the /etc/path_to_inst file for ge instances. For Sun GigabitEthernet/P: # grep ge /etc/path_to_inst “/pci@1f,4000/pci@1/network@1” 1 “ge” For Sun GigabitEthernet/S: # grep ge /etc/path_to_inst “/sbus@1f,0/network@1,100000” 1 “ge” In these examples, the 0 instance is for the first GigabitEthernet adapter installed in each system.

Page 8: Configuring The Driver Parameters
Configuring the Driver Parameters This section provides an overview of the capabilities of the GigabitEthernet ASIC used in the adapters, lists the available ge driver parameters, and describes how to configure these parameters. The ge driver controls the Sun GigabitEthernet adapter devices. The Sun GigabitEthernet device is identified as network with the model property SUNW,sbus-gem or SUNW,pci-gem node. -

Page 11: Interpacket Gap Parameters
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. lists the default values and allowable values for the IPG parameters, ipg1 TABLE 4 and ipg2. -

Page 15: To Specify The Device Instance For The Ndd Utility
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 associated with a particular device. -
Page 16: To Use The Ndd Utility In Non-Interactive Mode
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 utility passes value, which must be specified down to the named /dev/ge driver instance, and assigns it to the parameter: # ndd -set /dev/ge parameter value... -
Page 17: Autonegotiation Mode
To list all the parameters supported by the ge driver, type ndd /dev/ge \?. (See through for parameter descriptions.) TABLE 1 TABLE 8 # ndd /dev/ge \? (read only) link_status (read only) link_speed (read only) link_mode (read only) ipg1 (read and write) ipg2 (read and write) instance... -
Page 18: Setting Parameters Using The Ge.conf File
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 by creating a ge.conf file in the /kernel/drv directory. Use a ge.conf file when you need to set a particular parameter for a device in the system. The parameters you set are read and write parameters that are listed in “Driver Parameter Values and Definitions”... -
Page 19: To Set Parameters Using The Ge.conf File On An Sbus Adapter
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 device unambiguously in the ge.conf file, use the name, parent name, and the unit-address for the device. -
Page 20: To Set Parameters Using The Ge.conf File On A Pci Adapter
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. name=”pci108e,2bad” parent=”/pci@4,4000” unit-address=”4” ipg1=20 ipg2=10; name=”pci108e,2bad” parent=”/pci@6,2000” unit-address=”1” ipg1=20 ipg2=10; name=”pci108e,2bad” parent=”/pci@4,2000” unit-address=”1” ipg1=20 ipg2=10;... - Page 21 1. At the command line, use the grep command to search the /etc/path_to_inst file for ge interfaces. For Sun GigabitEthernet/P: The following example shows the device instance from an adapter installed in slot 1. # grep ge /etc/path_to_inst “/pci@1f,4000/network@1” 0 “ge” For Sun GigabitEthernet/S: The following example shows the device instance from an adapter installed in slot 0.

Page 22: To Set Up A Diskless Client On A Server
3. Create an appropriate entry in the /etc/hosts file for each active ge interface. For example: # cat /etc/hosts # Internet host table 127.0.0.1 localhost 129.144.10.57 zardoz loghost 129.144.11.83 zardoz-11 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 server so that you can boot and run diskless clients across a GigabitEthernet network. -
Page 23: To Perform A Net-Install Of The Solaris Environment Over The Ge Interface
To Perform a Net-Install of the Solaris Environment Over the ge Interface This procedure is applicable only if you are installing the Solaris operating environment over the network using the ge interface. Note – The Solaris CD-ROM cannot be used to perform a net-install since it is a read-only medium. - Page 24 3. At the ok prompt, type: ok show-nets The show-nets command lists the system devices. You should see the full path name of the network device, similar to the examples below. For Sun GigabitEthernet/P: a) /pci@1f,0/pci@1/network@3 b) /pci@1f,0/pci@1,1/network@1,1 q) NO SELECTION Enter Selection, q to quit: For Sun GigabitEthernet/S: a) /sbus@1f,0/network@1,100000...
