Installing and Configuring the ge

Device Driver

These Platform Notes include instructions for installing and configuring the

software u sed 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.

The document is organized as follows:

■ Installing the Driver Software

■ Configuring the Driver Parameters

■ Setting ge Driver Parameters

■ Network Configuration

Installing the Driver Software

The software required to use the Sun GigabitEthernet adapters is on the Solaris CD

that accompanies these Platform Notes.

▼ To Install the Driver Software

1. Become superuser.

Download from Www.Somanuals.com. All Manuals Search And Download.

2. Use the prtconf -pvcommand 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. Install the software.

■ If your system contains a gedevice, install the software as described in the

Solaris 7 3/99 Sun Hardware Platform Guide.

■ If your system does not contain a gedevice, shut down the system and install

the adapter, then install the driver software as described in the Solaris 7 3/99 Sun

Hardware Platform Guide

Note – If your system supports Dynamic Reconfiguration (DR), do not shut down

or reboot. Refer to the installation manual that shipped with your system for further

installation instructions.

▼ Set Up the Software on Solaris Systems

1. Create an entry in the /etc/hostsfile for each active geinterface.

# cat /etc/hosts

# Internet host table

127.0.0.1

localhost

129.144.10.57 zardoz

loghost

129.144.11.83 zardoz-11

2. Use the grepcommand to search the /etc/path_to_instfile for geinstances.

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 0instance is for the first GigabitEthernet adapter installed in

each system.

3. Set up each hostname.genum file to correspond with each gedevice in the

path_to_instfile.

The following example shows the /etc/hostname.genum file required for a

system that has a geinterface with the host name zardoz-11.

# cat /etc/hostname.ge1

zardoz-11

4. Set up the geadapter using the ifconfigcommand, where ip_address is the

system IP address of the machine that will use the adapter without first rebooting.

# ifconfig ge0 plumb

# ifconfig ge0 ip_address up

Note – After installing the software, refer to the Sun GigabitEthernet/S 2.0 Adapter

Installation and User’s Guide or the Sun GigabitEthernet/P 2.0 Adapter Installation and

User’s Guide for further information about how to configure the software.

Configuring the Driver Parameters

This section provides an overview of the capabilities of the GigabitEthernet ASIC

used in the adapters, lists the available gedriver parameters, and describes how to

configure these parameters.

The gedriver controls the Sun GigabitEthernet adapter devices. The Sun

GigabitEthernet device is identified as networkwith the model property

SUNW,sbus-gemor SUNW,pci-gemnode. The gedriver is attached to the device

with the compatible property pci108e,2badfor the Sun GigabitEthernet/ P adapter

or SUNW,sbus-gemfor the Sun GigabitEthernet/ S adapter. You can manually

configure the parameters to customize each Sun GigabitEthernet adapter in your

system.

GigabitEthernet MAC

The GigabitEthernet MAC (GEM) provides 1000BASE-SX networking interfaces. The

driver automatically sets the link speed to 1000 Mbps and conforms to the IEEE

802.3z Ethernet standard. The GEM PCI ASIC provide the PCI interface, Media

Access Control (MAC) functions, and Physical Code Sublayer (PCS) functions. The

GEM SBus ASIC provides the SBus interface, MAC functions, and PCS functions.

The External SERDES, which connects the 1000BASE-SX Compliant SC connector to

the ASIC, provides the physical layer functions.

The GEM MAC and PCS are capable of all the operating speeds and modes listed in

“Autonegotiation Mode” on page 13. The PCS performs autonegotiation with the

remote end of the link (link partner) to select a common mode of operation.

The PCS also supports a forced mode of operation. You can select the speed and

mode by creating a ge.conffile.

Flow Control Parameters

The GEM ASIC is capable of sourcing (transmitting) and terminating (receiving)

pause frames conforming to IEEE 802.3x Frame Based Link Level Flow Control

Protocol. In response to received flow control frames, the GEM can slow down its

transmit rate. On the other hand, GEM is capable of sourcing flow control frames,

requesting the link partner to slow down, provided that the link partner supports

this feature. By default, GEM advertises Receive PAUSE capability during

autonegotiation.

Parameter

Values

(on/off)

Description

adv_pauseTX

adv_pauseRX

0, 1

Transmit PAUSE Capable (default: not capable)

Receive PAUSE Capable (default: capable)

For normal operations, GEM doesn’t need to source flow control frames. However, if

GEM is operating on a slow bus (for instance, a 33-MHz PCI bus slot), and there is a

lot of frame reception activity, there could be a performance degradation due to

Receive FIFO overflow. If the link partner is capable of terminating PAUSE flow

control frames, the performance of GEM could be improved by enabling

adv_pauseTX and restarting autonegotiation.

Interpacket Gap Parameters

The GEM ASIC supports the programmable Interpacket Gap (IPG) parameters ipg1

and ipg2. The total IPG is the sum of ipg1and ipg2: 0.096 microseconds for the

link speed of 1000 Mbps.

TABLE 4 lists the default values and allowable values for the IPG parameters, ipg1

and ipg2.

TABLE 4

Read-Write Interpacket Gap Parameter Values and Descriptions

Parameter

Values

Description

(Byte-time)

ipg1

ipg2

0, 255

ipg1= 8 (default at initialization)

ipg2= 4 (default at initialization)

By default, the driver sets ipg1to 8-byte time and ipg2to 4-byte time, which are

the standard values. (Byte time is the time it takes to transmit one byte on the link,

with a link speed of 1000 Mbps.)

If your network has systems that use longer IPG (the sum of ipg1and ipg2) and if

those machines seem to be slow in accessing the network, increase the values of

ipg1and ipg2to match the longer IPGs of other machines.

Defining an Additional Delay Before Transmitting

a Packet Using lance_modeand ipg0

The GEM ASIC supports a programmable mode called lance_mode. The ipg0

parameter is associated with lance_mode.

If lance_modeis enabled (the default), an additional delay is added by setting the

ipg0parameter before transmitting the packet. This delay is in addition to the delay

set by the ipg1and ipg2parameters. The additional delay set by ipg0helps to

reduce collisions. Systems that have lance_modeenabled might not have enough

transmission time on the network.

If lance_modeis disabled, the value of ipg0is ignored and no additional delay is

set. Only the delays set by ipg1and ipg2are used. Disable lance_modeif other

systems keep sending a large number of back-to-back packets.

You can add the additional delay by setting the ipg0parameter from 0 to 31, which

is the media byte time delay.

If the link partner is capable of autonegotiation (when lp_autoneg_capis 1), the

speed and mode information is displayed when you use autonegotiation and get the

link partner capabilities.

Setting geDriver Parameters

You can set the gedriver parameters in two ways, depending on your needs:

■ Using the ndd utility

■ Using the ge.conffile

Use the nddutility to set parameters that are valid until you reboot the system. It is

also a good way to test parameter settings.

Use the ge.conf file to set parameters so they remain in effect after you reboot the

system. Create a /kernel/drv/ge.conffile and add parameter values to this file

when you need to set a particular parameter for a device in the system.

Setting Parameters Using the nddUtility

Use the nddutility to configure parameters that are valid until you reboot the

system. The nddutility supports any networking driver that implements the Data

Link Provider Interface (DLPI).

The following sections describe how you can use the gedriver and the nddutility to

modify (with the -setoption) or display (without the -setoption) the parameters

for each gedevice.

Platform Notes: The Sun GigabitEthernet Device Driver • March 1999

Download from Www.Somanuals.com. All Manuals Search And Download.

▼ To Specify the Device Instance for the ndd

Utility

Before you use the nddutility to get or set a parameter for a gedevice, you must

specify the device instance for the utility.

1. Check the /etc/path_to_instfile to identify the instance associated with a

particular device.

For Sun GigabitEthernet/P:

# grep ge /etc/path_to_inst

“/pci@4,4000/network@4” 2 “ge”

“/pci@6,2000/network@1” 1 “ge”

“/pci@4,2000/network@1” 0 “ge”

In this example, the three GigabitEthernet instances are from the adapters installed

in perspective PCI slots.

For Sun GigabitEthernet/S:

# grep ge /etc/path_to_inst

“/sbus@b,0/network@2,100000” 0 “ge”

In this example, the GigabitEthernet instance is from an adapter installed in a

perspective SBus slot.

2. Use the instance number to select the device.

# ndd -set /dev/ge instance instance_number

The device remains selected until you change the selection.

Non-Interactive and Interactive Modes

You can use the nddutility in two modes:

■ Non-interactive

■ Interactive

In non-interactive mode, you invoke the utility to execute a specific command. Once

the command is executed, you exit the utility. In interactive mode, you can use the

utility to get or set more than one parameter value. (Refer to the ndd(1M)man page

for more information.)

Installing and Configuring the geDevice Driver

Download from Www.Somanuals.com. All Manuals Search And Download.

▼ To Use the nddUtility in Non-Interactive Mode

This section describes how to modify and to display parameter values.

1. To modify a parameter value, use the -setoption.

If you invoke the nddutility with the -setoption, the utility passes value, which

must be specified down to the named /dev/gedriver instance, and assigns it to the

parameter:

# ndd -set /dev/ge parameter value

2. To display the value of a parameter, specify the parameter name (and omit the

value).

When you omit the -setoption, a query operation is assumed and the utility

queries the named driver instance, retrieves the value associated with the specified

parameter, and prints it:

# ndd /dev/ge parameter

▼ To Use the nddUtility in Interactive Mode

● To modify a parameter value in interactive mode, specify ndd /dev/ge, as shown

below.

The nddutility then prompts you for the name of the parameter:

# ndd /dev/ge

name to get/set? (Enter the parameter name or ? to view all

parameters)

▼ To View the geDriver Parameters

After entering the parameter name, the nddutility prompts you for the parameter

value (see TABLE 1 through TABLE 8).

Platform Notes: The Sun GigabitEthernet Device Driver • March 1999

Autonegotiation Mode

By default, autonegotiation is set to on. This means that the adapter will

communicate with its link partner to determine a compatible network speed, duplex

mode, and flow control capability.

If your network equipment does not support autonegotiation, or if you want to

specify your network speed, you can set autonegotiation to offon the gedevice.

▼ To Set Autonegotiation to Off (Forced Mode)

1. Select the following parameters: adv_1000fdx_cap, adv_1000hdx_cap,

adv_pauseTXand adv_pauseRX, and set those values according to the user’s

manual that shipped with your link partner device (for example, switch). See

TABLE 6 for parameter values.

Installing and Configuring the geDevice Driver

Download from Www.Somanuals.com. All Manuals Search And Download.

2. Set adv_1000autoneg_capto 0.

Setting Parameters Using the ge.confFile

You can also specify the properties described in this section on a per-device basis by

creating a ge.conffile in the /kernel/drvdirectory. Use a ge.conffile 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” on page 5.

The man pages for prtconf(1M)and driver.conf(4)include additional

details.

Understanding the ge.confFile

● Obtain the hardware path names for the gedevices in the device tree.

Typically the path names and the associated instance numbers will be present in the

/etc/path_to_instfile.

# grep ge /etc/path_to_inst

“/sbus@b,0/network@2,100000” 0 “ge”

■ where:

■

“/ sbus@b,0/ network@2,100000” specifies the hardware node name in the

device tree.

■

“0” is the instance number.

“ge” is the driver name.

■ In the device path name, the last component after the last /character and before

the @character (network) is the device name.

■ The path name before the last component (sbus@b,0) is the parent name.

For Sun GigabitEthernet/S:

To identify an SBus device unambiguously in the ge.conffile, use the name and

parent name of the device. Refer to the sbus(4) man page for more information

about the SBus device specification.

In the previous example:

■ Name = SUNW,sbus-gem

■ Class = “sbus”

Platform Notes: The Sun GigabitEthernet Device Driver • March 1999

Download from Www.Somanuals.com. All Manuals Search And Download.

Note – The “name” property in the ge.conffile 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 .propertiesfile.

For Sun GigabitEthernet/P:

To identify a PCI device unambiguously in the ge.conffile, use the name, parent

name, and the unit-address for the device. Refer to the pci(4) man page for more

information about the PCI device specification.

In the first line of the previous example:

■ Name = pci108e,2bad

■ Parent = /pci@4,4000

■ Unit-address = 4

In the second line in the previous example:

■ Name = pci108e,2bad

■ Parent = /pci@6,2000

■ Unit-address = 1

In the third line in the previous example:

■ Name = pci108e,2bad

■ Parent = /pci@4,2000

■ Unit-address = 1

▼ To Set Parameters Using the ge.confFile on an SBus

adapter

1. Set the ipg1and ipg2parameters for the above devices in the

kernel/drv/ge.conffile.

name = “SUNW,sbus-gem” class = “sbus”

reg=0x2,0x100000,0x14,0x2,0x200000,0x9060 ipg1=20 ipg2=10 ;

2. Save the ge.conffile.

3. Save and close all files and programs, and exit the windowing system.

4. If your system doesn’t support DR, reboot by typing the init 6command at the

superuser prompt.

name=”pci108e,2bad” parent=”/pci@4,2000” unit-address=”1” ipg1=20

ipg2=10;

2. Save the ge.conffile.

3. Save and close all files and programs, and exit the windowing system.

4. Halt and reboot the system by typing the init 6command at the superuser

prompt.

Network Configuration

This section describes how to configure the driver after it has been installed on your

system.

▼ To Configure the Host Files

After installing the Sun GigabitEthernet adapter driver software, you must create a

file for the adapter’s Ethernet interface. You must also create both an IP address and

a host name for the Ethernet interface in the /etc/hostsfile.

Platform Notes: The Sun GigabitEthernet Device Driver • March 1999

Download from Www.Somanuals.com. All Manuals Search And Download.

1. At the command line, use the grepcommand to search the /etc/path_to_inst

file for geinterfaces.

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.

# grep ge /etc/path_to_inst

“/sbus@1f,0/network@1” 0 “ge”

2. Create an /etc/hostname.ge<num> file, where num is the instance number of

the geinterface you plan to use.

If you wanted to use the adapter’s geinterface in the Step 1 example, you would

need to create a /etc/hostname.ge0file, where 0is the number of the ge

interface. If the instance number were 1, the file name would be

/etc/hostname.ge1.

■ Do not create an /etc/hostname.genum file for a Sun GigabitEthernet adapter

interface you plan to leave unused.

■ The /etc/hostname.genum file must contain the host name for the appropriate

geinterface.

■ The host name should have an IP address and should be entered in the

/etc/hostsfile.

■ The host name should be different from any other host name of any other

interface: for example, /etc/hostname.ge0and /etc/hostname.ge1cannot

share the same host name.

The following example shows the /etc/hostname.genum file required for a

system called zardozthat has a Sun GigabitEthernet adapter (zardoz-11).

# cat /etc/hostname.ge0

zardoz

# cat /etc/hostname.ge1

zardoz-11

3. Create an appropriate entry in the /etc/hostsfile for each active geinterface.

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.

1. Determine the client’s root directory onto which you want to install the gedriver.

For the following example, the root directory is

# /export/root/client_name

2. Use pkgaddto install the gedriver in the root partition of the diskless client on

the server, where x is 5.1+ for Solaris 2.5.1+, 6 for Solaris 2.6, or 7 for Solaris 7.

# pkgadd -R /export/root/client_name —d \

/cdrom/sun_gigabitethernet_2_0/Sol_2.x

3. Set up the /export/root/client_name/hostname.genum file. See “Network

Configuration” on page 16.

▼ To Perform a Net-Install of the Solaris

Environment Over the geInterface

This procedure is applicable only if you are installing the Solaris operating

environment over the network using the geinterface.

Note – The Solaris CD-ROM cannot be used to perform a net-install since it is a

read-only medium. You must use the Solaris CD image archive to update certain

software files.

1. Determine the root directory of the system that will be net-installed.

For example, if the Solaris software is located within a directory named DIR, and the

system being net-installed is already configured, then find the root directory with

the /etc/bootparamsfile.

# grep client_name /etc/bootparams

If the system being net-installed is not already configured, refer to the Solaris

documentation that shipped with your system for configuration instructions.

2. Install the appropriate OS driver support in the client’s root directory.

For example, if you are adding the gedriver to the Solaris 2.5.1+ net-install client’s

root directory, type:

# pkgadd -R /DIR/export/exec/kvm/sparc.Solaris_2.5.1+ -d \

/cdrom/sun_gigabitethernet_2_0/Sol_2.x

For example, if you are adding the gedriver to the Solaris 2.6 or 7 net-install client’s

root directory, type (where x is 6 for Solaris 2.6 or 7 for Solaris 7):

# pkgadd -R /DIR/Sol_2.x/etc/Tools/Boot -d \

/cdrom/sun_gigabitethernet_2_0/Sol_2.x
