CHAPTER

Installing the Adapter

This chapter describes how to install the adapter in your system and verify that it has been installed correctly. It then describes how to install the driver software using the automated script. Finally, this chapter describes how to edit the network host files after installing the adapter on your system.

This chapter contains the following sections:

■ “Installing the Adapter With Dynamic Reconfiguration” on page 7

■ “Installing the Adapter Without Dynamic Reconfiguration” on page 8

■ “Using the Installation Script” on page 14

■ “Verifying the Software Installation” on page 21

■ “Configuring the Network Host Files” on page 22

Note – If you are installing the Sun GigaSwift Ethernet adapter in a machine

running the Solaris 9 x86 Operating System, the following features are not supported: diskless client, installing the Solaris Operating System over this adapter, using this adapter as the primary boot device.

Installing the Adapter With Dynamic Reconfiguration

If you have a Sun Enterprise system that supports dynamic reconfiguration (DR), you do not have to reboot your system after installing the adapter.

The process of adding and configuring an adapter with DR involves connecting the attachment point and configuring its occupant. In most cases, the cfgadm(1M) command can perform both steps at once.

Note – Dynamic reconfiguration (DR) is a system-specific feature. If you have a Sun

Enterprise system that supports DR, refer to the Sun Enterprise Dynamic Reconfiguration User’s Guide and your system’s documentation for further

information about DR.

Installing the Adapter Without Dynamic Reconfiguration

▼ To Install the Adapter

Note – The following instructions describe the basic tasks required to install the

adapter. Refer to your system installation or service manual for detailed PCI adapter installation instructions.

1. Halt and power off your system.

2. Power off all of the peripherals connected to your system.

3. Open the system unit.

4. Attach the adhesive copper strip of the antistatic wrist strap to the metal casing of the power supply. Wrap the other end twice around your wrist, with the adhesive side against your skin.

5. Holding the PCI adapter by the edges, unpack it and place it on an antistatic surface.

6. Using a No. 1 Phillips screwdriver, remove the PCI filler panel from the slot in which you want to insert the PCI adapter.

Save the filler panel screw for Step 9.

7. Holding the PCI adapter by the edges, align the adapter edge connector with the PCI slot. Slide the adapter face plate into the small slot at the end of the PCI opening.

8. Applying even pressure at both corners of the adapter, push the PCI adapter until it is firmly seated in the slot.

8 Sun GigaSwift Ethernet Adapter Installation and User’s Guide • August 2004

Caution – Do not use excessive force when installing the adapter into the PCI slot.

You might damage the adapter’s PCI connector. If the adapter does not seat properly when you apply even pressure, remove the adapter and carefully reinstall it.

9. Secure the adapter to the PCI slot using the screw you removed in Step 6.

10. Detach the wrist strap and close the system unit.

11. Connect the Ethernet cables. a. Connect one end of the Ethernet cable to the port on the card. b. Connect the other end of the Ethernet cable to an active Ethernet network.

We are observing that the EMI shielding around the PCI slots is quite flimsy. When we install a PCI card, sometimes, the EMI shielding become loose and

touches the metal traces/pins at the back of the card. For the Quad Gigabit card (x4444a), the shield actually touches the LED pins and makes the link/activity LEDs go off/on by itself.

Also, when a full length PCI card is pulled out, it can easily pull the complete EMI shield with it.

Note – Green LEDs will not light until the correct driver is installed.

▼ To Verify the Hardware Installation

After you have installed the Sun GigaSwift Ethernet adapter, but before you boot your system, perform the following tasks to verify the installation. Refer to the your Solaris documentation for the detailed instructions.

Note – Verification is not required if your system supports DR. Verification is not

supported if your system is running Solaris 9 x86 software.

1. Power on the system, and when the banner appears, press the Stop-A key sequence to interrupt the boot process and display the OpenBoot (ok) prompt.

Chapter 2 Installing the Adapter 9

2. List the network devices on your system.

ok show-nets

You should see the full path name of the network devices, similar to the example below. In this example, the network@0 and the network@1 devices are the Sun GigaSwift Ethernet adapter, and the network@2 is the onboard Ethernet device.

ok show-nets a) /pci@8,600000/network@1 b) /pci@8,700000/network@5,1 q) NO SELECTION Enter Selection, q to quit:

/pci@8,600000/network@1 identifies the Ethernet port

Note – If you do not see the device listed, check that the adapter is properly seated.

If necessary, reinstall the adapter.

3. View the device that you installed.

Using the previous example, type:

cd /pci@8,600000/network@1

10 Sun GigaSwift Ethernet Adapter Installation and User’s Guide • August 2004

4. View the .properties file for a list of device properties.

The .properties command displays the specific information about the installed adapter. If you are using the Sun GigaSwift Ethernet MMF adapter, your output will be similar to the following.

Note – If you are going to set the local-mac-address? variable, note the local

MAC address of your device at this time. See “Setting the local-mac-address? Variable” on page 13 for more information.

5. Type the following when you finish looking at the .properties values:

ok device-end

Setting the local-mac-address? Variable

Note – Enabling the local-mac-address? variable is only required if you boot

from the network. Setting the local-mac-address? variable is not supported in systems running Solaris 9 x86 software.

Every Sun GigaSwift Ethernet adapter comes with a unique media access control (MAC) address that represents the 48-bit Ethernet address for that interface.

A system with a a system-wide MAC address is not obligated to use this assigned MAC address. In such cases, the system-wide MAC address applies to all network interfaces on the system.

The local-mac-address? variable of the network device specifies the network address (system-wide or local-mac-address?) used for booting the system. If the local-mac-address? NVRAM variable is set to true, the system sets the MAC address for the network interface of the Sun GigaSwift Ethernet adapter to be the address provided by the adapter. If this variable is set to false, the system sets the MAC address for the adapter’s network interface to be the same as the system MAC address.

To start using the MAC address assigned to the network interface of the Sun GigaSwift Ethernet adapter, set the NVRAM configuration variable

local-mac-address? to true.

ok setenv local-mac-address? true

▼ To Set the Gigabit Ethernet Device as the Primary Boot

Device

Use this procedure only if you want the Gigabit Ethernet device to be your primary boot device.

Chapter 2 Installing the Adapter 13

1. List the network devices on your system.

ok show-nets a) /pci@8,600000/network@1 b) /pci@8,700000/network@5,1 q) NO SELECTION Enter Selection, q to quit:q

2. Set the Sun GigaSwift Ethernet adapter device to be your default boot device.

ok setenv boot-device /pci@8,600000/network@1

Note that the command shown in this example sets your boot device to be port 0 on the network portion of the card.

Rebooting the System

After verifying the adapter installation, use the boot -r command to perform a reconfiguration boot on your system.

ok boot -r

Using the Installation Script

The Sun GigaSwift Ethernet CD provides automated installation for the GigaSwift Ethernet driver software. In most cases, you can use the following procedure and execute the installation script. If you have any problems, see Appendix A for manual installation procedures.

When you have executed the script, select the interface card that is installed on your system. For this product, select the “Sun GigaSwift Ethernet Adapter.”

The script first checks to ensure that the software driver package has already been installed. If the package is installed, the script verifies the patch level and updates the driver with the updated patch if necessary. If the packages are not installed on Solaris 8 or 9 software, the installation script installs the latest prepatched packages. If the system does not require updating because the patch level is at or beyond the current install version, the script exits with an appropriate message.

14 Sun GigaSwift Ethernet Adapter Installation and User’s Guide • August 2004

Verifying the Software Installation

Unless you have the latest version of the driver software installed, the green LEDs on the adapter will not go on. If you are using a SPARC system, be sure that you have version 1.136 or later installed.

Chapter 2 Installing the Adapter 21

● Use the modinfo command to verify that you have the current driver (v1.136 or

later) installed.

If you type grep CE, using uppercase letters, you will get only the specific driver information:

# modinfo |grep CE 84 7821c000 4f9a6 75 1 ce (CE Ethernet Driver v1.136)

If you type grep ce, using lowercase letters, you will still get the driver version information, but you will also get several lines of additional information. Your output will be similar to the following. The line showing the driver version is in bold italics.

# modinfo |grep ce 11 1018bacb 1f7 - 1 fssnap_if (File System Snapshot Interface) 12 1018bc1b 10900 1 1 rpcmod (rpc interface str mod) 13 10199c5b 66f10 3 1 ip (IP Streams device) 35 1026ba5c 1ae7 - 1 busra (Bus Resource Allocator (BUSRA) ) 36 1026d290 c4c - 1 hpcsvc (hot-plug controller services v1) 47 102663c6 304 143 1 ip6 (IP Streams device) 48 10296ed4 25e08 42 1 tcp (TCP Streams device) 50 1026650a 365 146 1 tcp6 (TCP Streams device) 51 10278264 9968 41 1 udp (UDP Streams device) 52 10234ef7 365 145 1 udp6 (UDP Streams device) 53 10280174 7f10 5 1 icmp (ICMP Streams device) 54 102666af 30e 144 1 icmp6 (ICMP Streams device) 56 10260029 4bfb 10 1 timod (transport interface str mod) 71 102f6d1d 1c30 43 1 rts (Routing Socket Streams device)

Configuring the Network Host Files

After installing the driver software, you must create a hostname.cenumber file (Where number = the instance number of the ce interface.) for the adapter’s Ethernet interface. You must also create both an IP address and a host name for its Ethernet interface in the /etc/hosts file.

22 Sun GigaSwift Ethernet Adapter Installation and User’s Guide • August 2004

1. At the command line, use the grep command to search the /etc/path_to_inst file for ce interfaces.

# grep ce /etc/path_to_inst "/pci@8,600000/network@1" 0 "ce"

In the example above, the device instance is from a Sun GigaSwift Ethernet adapter. For clarity, the instance number is in bold italics.

2. Use the ifconfig command to set up the adapter’s ce interface.

Use the ifconfig command to assign an IP address to the network interface. Type the following at the command line, replacing ip-address with the adapter’sIP address:

# ifconfig ce0 plumb ip-address up

Refer to the ifconfig(1M) man page and the Solaris documentation for more information.

■ If you want a setup that remains the same after you reboot, create an

/etc/hostname.cenumber file, where number corresponds to the instance number of the ce interface you plan to use.

To use the adapter’s ce interface in the Step 1 example, create an /etc/hostname.ce0 file, where 0 is the number of the ce interface. If the instance number were 1, the filename would be /etc/hostname.ce1.

■ Do not create an /etc/hostname.cenumber file for a Sun GigaSwift Ethernet

adapter interface you plan to leave unused.

■ The /etc/hostname.cenumber file must contain the hostname and IP address

for the appropriate ce interface.

■ The host name and IP address must be listed in the /etc/hosts file.

■ The host name must be different from any other host name of any other interface,

for example: /etc/hostname.ce0 and /etc/hostname.ce1 cannot share the same host name.

The following example shows the /etc/hostname.cenumber file required for a system called zardoz that has a Sun GigaSwift Ethernet adapter (zardoz-11).

# cat /etc/hostname.hme0 zardoz # cat /etc/hostname.ce0 zardoz-11

Chapter 2 Installing the Adapter 23

3. Create an appropriate entry in the /etc/hosts file for each active ce 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

CHAPTER

Network Configuration

This chapter describes how to edit the network host files after the adapter has been installed on your system. This chapter contains the following sections:

■ “Configuring the Network Host Files” on page 25

■ “Setting Up a GigaSwift Ethernet Network on a Diskless Client System” on

page 27

■ “Installing the Solaris Operating System Over a GigaSwift Ethernet Network” on

page 28

Configuring the Network Host Files

After installing the driver software, you must create a hostname.cenumber file for the adapter’s Ethernet interface. You must also create both an IP address and a host name for its Ethernet interface in the /etc/hosts file.

1. At the command line, use the grep command to search the /etc/path_to_inst file for ce interfaces.

# grep ce /etc/path_to_inst "/pci@8,600000/network@1" 0 "ce"

In this example, the device instance is from a Sun GigaSwift Ethernet adapter installed in slot 1. For clarity, the instance number is in bold italics.

Be sure to write down your device path and instance, which in the example is

“/pci@1f,0/pci@1/network@4” 0. Your device path and instance will be similar.

You need this information to make changes to the ce.conf file. See “Setting Parameters Using the ce.conf File” on page 50.

2. Use the ifconfig command to set up the adapter’s ce interface.

Use the ifconfig command to assign an IP address to the network interface. Type the following at the command line, replacing ip-address with the adapter’sIP address:

# ifconfig ce0 plumb ip-address up

Refer to the ifconfig(1M) man page and the Solaris documentation for more information.

■ If you want a setup that remains the same after you reboot, create an

/etc/hostname.cenumber file, where number corresponds to the instance number of the ce interface you plan to use.

■ Do not create an /etc/hostname.cenumber file for a Sun GigaSwift Ethernet

adapter interface you plan to leave unused.

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

appropriate ce interface.

■ The host name must have an IP address listed in the /etc/hosts file.

■ The host name must be different from any other host name of any other interface,

for example: /etc/hostname.ce0 and /etc/hostname.ce1 cannot share the same host name.

The following example shows the /etc/hostname.cenumber file required for a system called zardoz that has a Sun GigaSwift Ethernet adapter (zardoz-11).

# cat /etc/hostname.hme0 zardoz # cat /etc/hostname.ce0 zardoz-11

3. Create an appropriate entry in the /etc/hosts file for each active ce 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

Setting Up a GigaSwift Ethernet Network on a Diskless Client System

Before you can boot and operate a diskless client system across a gigabit Ethernet network, you must first install the GigaSwift Ethernet software packages into the root directory of the diskless client. You can find the GigaSwift Ethernet software packages on the Sun GigaSwift Ethernet Driver CD. Refer to the Solaris Advanced Installation Guide and the System Administration Guide for more information about installing and administering diskless client systems.

Note – The Solaris 8 and Solaris 9 x86 versions of the operating system do not

support diskless clients.

▼ To Set Up a GigaSwift Ethernet Port on a

Diskless Client

1. Locate the root directory of the diskless client on the host server.

The root directory of diskless client system is commonly installed in the host server’s /export/root/client-name directory, where client_name is the diskless client’s host name. In this procedure, the root directory is:

/export/root/client-name

2. Insert the Sun GigaSwift Ethernet Driver CD into the server’s CD-ROM drive.

The CD should automatically mount to the /cdrom/cdrom0 directory. If the CD does not mount to this directory, see Appendix A for mounting instructions.

3. Use the pkgadd -R command to install the three GigaSwift Ethernet software packages to the diskless client’s root directory on the server.

Install the SUNWced.u, SUNWcedm, and SUNWcedu software packages to the client’s root directory.

# cd /cdrom/cdrom0/GigaSwiftEthernet/Packages # pkgadd -R /export/root/client-name -d . SUNWced.u SUNWcem SUNWcedu # cd /

Chapter 3 Network Configuration 27

4. Eject the Sun GigaSwift Ethernet Driver CD from the CD-ROM drive.

5. Create a hostname.cenumber file in the diskless client’s root directory.

You will need to create an /export/root/client-name/etc/hostname.cenumber file for the GigaSwift Ethernet interface. See “Configuring the Network Host Files” on page 25 for instructions.

6. Edit the hosts file in the diskless client’s root directory.

Edit the /export/root/client-name/etc/hosts file to include the IP address of the GigaSwift Ethernet interface. See “Configuring the Network Host Files” on page 25 for instructions.

7. Set the MAC address on the server side and rebuild the device tree if you want to boot from the GigaSwift Ethernet port.

8. To boot the diskless client from the GigaSwift Ethernet port, type the following boot command:

ok boot path-to-device:link-param, -v

Installing the Solaris Operating System Over a GigaSwift Ethernet Network

The Solaris Advanced Installation Guide describes the full procedure for installing the Solaris Operating System over the network. The following procedure assumes that you have created an install server, which contains the image of the Solaris CD, and that you have set up the client system to be installed over the network.

Note – The Solaris 9 x86 version of the operating system cannot be installed over a

GigaSwift Ethernet interface.

Before you can install the Solaris Operating System on a client system with a GigaSwift Ethernet adapter, you must first add the GigaSwift Ethernet software packages to the install server. These software packages are on Sun GigaSwift Ethernet Driver CD.

Note – Refer to the Solaris Advanced Installation Guide for more information about

installing the Solaris Operating System over the network.

28 Sun GigaSwift Ethernet Adapter Installation and User’s Guide • August 2004

▼ To Install the Solaris Operating System Over a

GigaSwift Ethernet Network

1. Prepare the install server and client system to install the Solaris Operating System over the network.

The Solaris Advanced Installation Guide describes how to create the install server and set up the client systems.

Note – If you want to install the client system over a network that is not part of the

same subnet, you must also create a boot server. The Solaris Advanced Installation Guide describes how to create a boot server.

2. Find the root directory of the client system.

The client system’s root directory can be found in the install server’s /etc/bootparams file. Use the grep command to search this file for the root directory.

# grep client-name /etc/bootparams client_name root=server-name:/netinstall/Solaris_2.7/Tools/Boot install=server-name:/netinstall boottype=:in rootopts=:rsize=32768

In this example, the root directory for the Solaris 7 client is /netinstall.InStep4, you would replace root-directory with /netinstall.

Note – If the root directory is not found in the /etc/bootparams file, refer to the

Solaris Advanced Installation Guide for configuration instructions.

3. Insert the Sun GigaSwift Ethernet Driver CD into the install server’s CD-ROM drive.

The CD should automatically mount to the /cdrom/cdrom0 directory. If the CD does not mount to this directory, see Appendix A for mounting instructions.

Chapter 3 Network Configuration 29

4. On the install server, install the GigaSwift Ethernet software to the client’s root directory, as determined in Step 2.

Replace root-directory with the location of the client’s root directory.

# cd /cdrom/cdrom0/GigaSwiftEthernet/Packages # ls SUNWce* SUNWcea SUNWceax SUNWced SUNWcedu SUNWcem # pkgadd -R root-directory/Solaris_2.7/Tools/Boot -d . SUNWced SUNWcem SUNWcedu # cd /

Note – If the commands above do not work correctly, refer to the documentation

that shipped with your version of the Solaris Operating System.

5. Eject the Sun GigaSwift Ethernet Driver CD from the CD-ROM drive.

Note – Perform the following steps on the client system.

6. Shut down and halt the client system.

Use the shutdown command to display the OpenBoot ( ok) prompt.

# shutdown -i0 -g0 -y . . . (shutdown command messages omitted) . . . ok

7. At the ok prompt, use the show-nets command to find the device path of the GigaSwift Ethernet device.

The show-nets command lists the system devices. You should see the full path name of the network device, similar to the example below. In this example, the

network@4 device is the Sun GigaSwift Ethernet adapter.

ok show-nets a) /pci@8,600000/network@1 b) /pci@8,700000/network@5,1 q) NO SELECTION Enter Selection, q to quit: q

30 Sun GigaSwift Ethernet Adapter Installation and User’s Guide • August 2004

8. At the ok prompt, boot the client system using the full device path of the Gigabit Ethernet device.

The following examples show the options available:

■ Booting in autonegotiated mode:

ok boot:link-param, -v

■ Booting in autonegotiated verbose mode at 1000 Mbps half-duplex:

ok boot /pci@1f,4000/network@4:speed=1000,duplex=half,link-clock=auto

Note – link-clock must be set to auto.

For this configuration, the highest capability is limited to 1000 Mbps half-duplex and the lowest is 10 Mbps half-duplex. The link is established within this range of capabilities, depending on the configuration of the link partner.

■ Booting in non-autonegotiated verbose mode at 100 Mbps full-duplex:

ok boot /pci@1f,4000/network@4:speed=100,duplex=full, -v

■ Booting in non-autonegotiated verbose mode at 1000 Mbps half-duplex link-clock

master:

ok boot /pci@1f,4000/network@4:speed=1000,duplex=half,link-clock=master

Note – For a link to be s uccessfully established, the link partner must be configured

to 1000 Mbps half-duplex link-clock slave.

9. Proceed with the Solaris Operating System installation.

Refer to the Solaris Advanced Installation Guide for more information about installing the Solaris Operating System over the network.

Chapter 3 Network Configuration 31

10. After installing the Solaris Operating System, install the Sun GigaSwift Ethernet software on the client system.

The software installed in Step 4 was required to boot the client system over the GigaSwift Ethernet interface. You now need to install the software in order for the operating system to use the client’s GigaSwift Ethernet interfaces in normal operation.

Before installing the Sun GigaSwift Ethernet software, make sure that the client system does not already have the software installed. Use the pkginfo command to see if the Sun GigaSwift Ethernet software packages are installed on the client system.

# pkginfo | grep SUNWce system SUNWced Sun Gigabit Ethernet Adapter Driver system SUNWcem Sun Gigabit Ethernet Adapter Driver Man Pages system SUNWcedu Sun Gigabit Ethernet Adapter Driver Headers

■ If the software is installed (as shown in the example above), skip to Step 11.

■ If the software is not installed, install the software from Solaris Supplement CD.

See Appendix A for instructions on installing the required software packages.

11. Confirm that the network host files have been configured correctly during the Solaris installation.

Although the Solaris software installation creates the client’s network configuration files, you may need to edit these files to match your specific networking environment. See “Configuring the Network Host Files ” on page 25 for more information about editing these files.

Booting Over the GigaSwift Ethernet Network

Note – The Solaris 9 x86 version of the operating system cannot be installed over a

GigaSwift Ethernet interface.

The Sun GigaSwift Ethernet adapter can be linked up either with autonegotiation enabled or disabled. When link-up is attempted with autonegotiation enabled (the default), the link parameter capabilities (such as speed in megabits/second, duplex and link-clock mastership only for 1000 Mbps) are automatically negotiated between

32 Sun GigaSwift Ethernet Adapter Installation and User’s Guide • August 2004

the device and its link partner. Attempting to link-up with autonegotiation disabled requires knowledge of the current capabilities at which both the device and its link partner are configured.

The structure of the boot net command line that includes device parameters is as follows:

ok boot device-path:speed=s,duplex=d,link-clock=c,promiscuous,

Where:

s = 1000, 100, 10, auto d = half, full, auto c = master, slave, auto

Note – Refer to the IEEE 802.3 (G)MII register specification for the details on

autonegotiated and non-autonegotiated modes of operation. (This establishes the link successfully so that traffic is transfered without collisions caused by duplex mismatch between the local and remote devices both the local and remote link capabilities must be matched.)

TABLE 3-1 depicts the device link parameters you can specify on the boot net

command line to establish a link between the local and remote device.

TABLE 3-2

shows the speed, duplex and link-clock capabilities at which a link-up will be attempted:

CHAPTER

Configuring Driver Parameters

This chapter describes how to configure the driver parameters used by the Sun GigaSwift Ethernet adapter. This chapter contains the following sections:

■ “GigaSwift Ethernet Driver Parameter Values and Definitions” on page 38

■ “Setting ce Driver Parameters” on page 46

■ “Usability Enhancements to the Driver” on page 52

■ “GigaSwift Ethernet Driver Operating Statistics” on page 54

GigaSwift Ethernet Device Driver Parameters

The ce device driver controls the GigaSwift Ethernet devices. The ce driver is attached to the UNIX pci name property pci108e,abba for the Sun GigaSwift Ethernet adapter (108e is the vendor ID and abba is the PCI device ID).

You can manually configure the ce device driver parameters to customize each Sun GigaSwift Ethernet adapter device in your system. This section provides an overview of the capabilities of the GigaSwift Ethernet device used in the adapter, lists the available ce device driver parameters, and describes how to configure these parameters.

The Sun GigaSwift Ethernet UTP PCI adapter is capable of all the operating speeds and modes listed in “Setting the Autonegotiation Mode” on page 49. The ce device performs autonegotiation with the remote end of the link (link partner) to select a common mode of operation. The ce device also supports Forced mode operation.

GigaSwift Ethernet Driver Parameter Values and Definitions

TABLE 4-1 describes the parameters and settings for the ce device driver.

Chapter 4 Configuring Driver Parameters 39

Note – If a parameter’s initial setting is 0, it cannot be changed. If you try to change

the setting, it will revert back to 0.

If all these parameters are set to 1, autonegotiation uses the highest speed possible. If all these parameters are set to 0, you receive the following error message:

NOTICE: Last setting will leave ce0 with no link capabilities. WARNING: ce0: Restoring previous setting.

Flow Control Parameters

The ce device is capable of sourcing (transmitting) and terminating (receiving) pause frames conforming to the IEEE 802.3x Frame Based Link Level Flow Control Protocol. In response to received flow control frames, the ce device can slow down its transmit rate. The ce device is capable of sourcing flow control frames by requesting the link partner to slow down, provided that the link partner supports this feature. By default, the driver advertises both transmit and receive pause capability during autonegotiation.

TABLE 4-3 provides flow control keywords and describes their function.

TABLE 4-3 Read-Write Flow Control Keyword Descriptions

Keyword Description

adv_asmpause_cap The adapter supports asymmetric pause, which means it

can pause only in one direction. 0=Off (default) 1=On

adv_pause_cap This parameter has two meanings, each depending on the

value of adv_asmpause_cap. (Default=0)

• If adv_asmpause_cap = 1 while adv_pause_cap =1, pauses are received.

• If adv_asmpause_cap = 1 while adv_pause_cap =0, pauses are transmitted.

• If adv_asmpause_cap = 0 while adv_pause_cap =1, pauses are sent and received.

• If adv_asmpause_cap = 0, then adv_pause_cap determines whether Pause capability is on or off.

40 Sun GigaSwift Ethernet Adapter Installation and User’s Guide • August 2004

Gigabit Link Clock Mastership Controls

The concept of link clock mastership was introduced with gigabit twisted-pair technology. One side of the link is the master that provides the link clock and the other side is the slave that uses the link clock. Once this relationship is established, the link is up, and data can be communicated. Two physical layer parameters control whether your side is the master or the slave, or whether mastership is negotiated with the link partner.

TABLE 4-4 Forced Mode Parameters

Parameter Description

master-cfg-enable Determines whether or not during the autonegotiation process

the link clock mastership is setup automatically.

master-cfg-value • If the master-cfg-enable parameter is set, then the

mastership is not set up automatically but depends on the value of master-cfg-value.

• If the master-cfg-value is set then the physical layer expects the local device to be the link master.

• If the master-cfg-value is not set then the parameter expects the link partner to be the master.

• If autonegotiation is not enabled, then the value of mastercfg-enable is ignored and the value of master-cfg-value

is key to the link clock mastership.

• If the master-cfg-value is set, then the physical layer expects the local device to be the link master.

• If the master-cfg-value is not set then the parameter expects the link partner to the master.

Table describes the Forced mode parameters.

Caution – Do not adjust the link clock mastership parameters unless you clearly

understand the settings of the link partner. Incorrect link clock mastership configuration results in link-up failure.

Interpacket Gap Parameters

The ce device supports a programmable mode called enable_ipg0. When an instance receives a packet with enable_ipg0 set (the default), it adds an

additional time delay before transmitting the packet. This delay, set by the ipg0 parameter, is in addition to the delay set by the ipg1 and ipg2 parameters. The additional ipg0 delay helps reduce collisions.

Chapter 4 Configuring Driver Parameters 41

If enable_ipg0 is disabled, the value of ipg0 is ignored and no additional delay is set. Only the delays set by ipg1 and ipg2 will be used. Disable enable_ipg0 if other systems keep sending a large number of back-to-back packets. Systems that have enable_ipg0 set might not have enough time on the network.

You can add the additional delay by setting the ipg0 parameter from 0 to 255, which is the media byte time delay.

TABLE 4-5 defines the enable_ipg0 and ipg0 parameters.

TABLE 4-5 Parameters Defining enable_ipg0 and ipg0

Parameter Values Description

enable_ipg0 0

ipg0 0 to 255 The additional time delay (or gap) before

enable_ipg0 reset enable_ipg0 set (Default=8)

transmitting a packet (after receiving the packet) (Default=8)

The ce device supports the programmable Interpacket Gap (IPG) parameters ipg1 and ipg2. The total IPG is the sum of ipg1 and ipg2. The total IPG is 0.096 microseconds for the link speed of 1000 Mbps.

TABLE 4-6 lists the default values and allowable values for the IPG parameters.

TABLE 4-6 Read-Write Interpacket Gap Parameter Values and Descriptions

Parameter Values

(Byte-time)

ipg1 0 to 255 Interpacket gap 1 (Default = 8) ipg2 0 to 255 Interpacket gap 2 (Default = 4)

Description

By default, the driver sets ipg1 to 8-byte time and ipg2 to 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 ipg1 and ipg2), and if those systems seem to be slow in accessing the network, increase the values of ipg1 and ipg2 to match the longer IPGs of other machines.

42 Sun GigaSwift Ethernet Adapter Installation and User’s Guide • August 2004

Interrupt Parameters

TABLE 4-7 describes the receive interrupt blanking values.

TABLE 4-7 RX Blanking Register for Alias Read

Field Name Values Description

rx_intr_pkts 0 to 511 Interrupt after this number of packets have arrived since

the last packet was serviced. A value of zero indicates no packet blanking. (Default=3)

rx_intr_time 0 to 524287 Interrupt after 4.5 US ticks have elapsed since the last

packet was serviced. A value of zero indicates no time blanking. (Default=1250)

Random Early Drop Parameters

TABLE 4-8 describes the RX random early detection 8-bit vectors, which allow you to

enable random early drop (RED) thresholds. When received packets reach the RED range packets are dropped according to the preset probability. The probability should increase when the FIFO level increases. Control packets are never dropped and are not counted in the statistics.

TABLE 4-8 RX Random Early Detecting 8-Bit Vectors

Field Name Values Description

red_dv4to6k 0 to 255 Random early detection and packet drop vectors for

when FIFO threshold is greater than 4096 bytes and fewer than 6,144 bytes. Probability of drop can be programmed on a 12.5 percent granularity. For example, if bit 0 is set, the first packet out of every eight will be dropped in this region. (Default=0)

Chapter 4 Configuring Driver Parameters 43

TABLE 4-8 RX Random Early Detecting 8-Bit Vectors

Field Name Values Description

red_dv6to8k 0 to 255 Random early detection and packet drop vectors for

when FIFO threshold is greater than 6,144 bytes and fewer than 8,192 bytes. Probability of drop can be programmed on a 12.5 percent granularity. For example, if bit 8 is set, the first packet out of every eight will be dropped in this region. (Default=0)

red_dv8to10k 0 to 255 Random early detection and packet drop vectors for

when FIFO threshold is greater than 8,192 bytes and fewer than 10,240 bytes. Probability of drop can be programmed on a 12.5 percent granularity. For example, if bit 16 is set, the first packet out of every eight will be dropped in this region. (Default=0)

red_dv10to12k 0 to 255 Random early detection and packet drop vectors for

when FIFO threshold is greater than 10,240 bytes and fewer than 12,288 bytes. Probability of drop can be programmed on a 12.5 percent granularity. For example, if bit 24 is set, the first packet out of every eight will be dropped in this region. (Default=0)

PCI Bus Interface Parameters

These parameters allow you to modify PCI interface features to gain better PCI interperformance for a given application.

TABLE 4-9 PCI Bus Interface Parameters

Parameter Description

tx_dma_weight Determines the multiplication factor for granting credit to the TX

side during a weighted round robin arbitration. Values are 0 to 3. (Default=0) 0 means no extra weighting. The other values are power of 2 extra weighting, on that traffic. For example if tx_dma_weight = 0 and rx_dma_weight = 3, then as long as RX traffic is continuously arriving its priority will be 8 access the PCI

times greater than TX to

44 Sun GigaSwift Ethernet Adapter Installation and User’s Guide • August 2004

TABLE 4-9 PCI Bus Interface Parameters

Parameter Description

rx_dma_weight Determines the multiplication factor for granting credit to the RX

side during a weighted round robin arbitration. Values are 0 to 3. (Default=0)

infinite_burst Enables the infinite burst capability to be utilized. When this is in

effect and the system supports infinite burs, the adapter does not free the bus until complete packets are transferred across the bus. Values are 0 or 1. (Default=0)

disable_64bit Switches off 64-bit capability of the adapter.

Values are 0 or 1. (Default=0, which enables 64 bit capability)

Jumbo Frames

The variable accept-jumbo enables the driver to instruct the upper layers that the driver is operating in Jumbo-frame mode.

Note – Jumbo-frame mode is not supported in systems running Solaris 9 x86

software.

TABLE 4-10 accept-jumbo Parameters

Parameter Values Description

accept-jumbo 1 Enables jumbo frames mode and sets MTU

to greater than 1500.

0 Jumbo frames is not enabled. MTU is at

1500.

In the Solaris 8 Operating System, accept-jumbo=1 does not take effect on the next

ifconfig. To get the maximum MTU setting use the following command:

# ifconfig ce0 mtu 9194

In the Solaris 9 Operating System, accept-jumbo=1 takes effect on next ifconfig, and automatically sets the MTU to 9194.

Although jumbo frames is configurable in 10/100 mode, jumbo frames is only supported in the Gigabit (1000Mbps) mode. Configuring jumbo frames enables the Ethernet interfaces to send and receive packets of up to 9216 bytes. However, the actual transfer size depends on the switch capability.

Chapter 4 Configuring Driver Parameters 45

Refer to the documentation that came with your switch for exact commands to configure jumbo frames support.

Jumbo Frames With Trunking 1.3

When using jumbo frames with Trunking 1.3, you must explicitly enable jumbo frames on each link participating in the Trunk.

▼ To Configure Jumbo Frames Using ndd

1. Bring down and unplumb the interface.

2. Set the instance number:

% ndd -set /dev/ce instance 0

In this example, the instance number set is 0.

3. Set the instance to accept jumbo frames:

% ndd -set /dev/ce accept-jumbo 1

4. Plumb the interface up:

% ifconfig ce0 plumb xx.xx.xx.xx up

Where

xx.xx.xx.xx = the IP address of the interface.

Setting ce Driver Parameters

You can set the ce device driver parameters in two ways:

■ Using the ndd utility

■ Using the ce.conf file

If you use the ndd utility, the parameters are valid only until you reboot the system. This method is good for testing parameter settings.

46 Sun GigaSwift Ethernet Adapter Installation and User’s Guide • August 2004

To set parameters so they remain in effect after you reboot the system, create a /platform/sun4u/kernel/drv/ce.conf file 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 ndd Utility

Use the ndd utility to configure parameters that are valid until you reboot the system. The ndd utility supports any networking driver that implements the Data Link Provider Interface (DLPI).

The following sections describe how you can use the ce driver and the ndd utility to modify (with the -set option) or display (without the -set option) the parameters for each ce device.

▼ To Specify Device Instances for the ndd Utility

Before you use the ndd utility to get or set a parameter for a ce 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.

# grep ce /etc/path_to_inst "/pci@8,600000/network@1" 0 "ce"

In this example, the Gigabit Ethernet instance is from the installed adapter. The instance number is in bold italics for clarity.

2. Use the instance number to select the device.

# ndd -set /dev/ce-instance-number

The device remains selected until you change the selection.

Noninteractive and Interactive Modes

You can use the ndd utility in two modes:

■ Noninteractive

■ Interactive

Chapter 4 Configuring Driver Parameters 47

In noninteractive 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.

▼ To Use the ndd Utility in Noninteractive Mode

This section describes how to modify and display parameter values.

● 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/ce driver instance, and assigns the value to the parameter:

# ndd -set /dev/ce parameter value

When you change any parameter, a message similar to the following appears:

ce0: xcvr addr:0x01 - link up 1000 Mbps full duplex

● To display the value of a parameter, specify the parameter name and omit the

value.

When you omit the -set option, the utility queries the named driver instance, retrieves the value associated with the specified parameter, and prints it:

# ndd /dev/ce parameter

▼ To Use the ndd Utility in Interactive Mode

● To modify a parameter value in interactive mode, specify ndd /dev/ce:

# ndd /dev/ce name to get/set? (Enter the parameter name or ? to view all parameters)

After you enter the parameter name, the ndd utility prompts you for the parameter value (see

TABLE 4-1 through TABLE 4-12).

48 Sun GigaSwift Ethernet Adapter Installation and User’s Guide • August 2004

● To list all the parameters supported by the ce driver, type ?.

Setting the Autonegotiation Mode

By default, autonegotiation is set to on. This means that the adapter communicates with its link partner to determine a compatible network speed, duplex mode, and flow control capability.

Chapter 4 Configuring Driver Parameters 49

▼ To Disable Autonegotiation Mode

If your network equipment does not support autonegotiation, or if you want to specify your network speed, you can set autonegotiation to off on the ce device.

Note – Disabling autonegotiation mode can cause collisions.

1. Set the following driver parameters to the values that are described in the documentation that shipped with your link partner (for example, a switch):

■ adv-1000fdx-cap

■ adv-100fdx-cap

■ adv-100hdx-cap

■ adv-10fdx-cap

■ adv-10hdx-cap

■ adv-asmpause-cap

■ adv-pause-cap

TABLE 4-2 for the descriptions and possible values of these parameters.

See

Note – According to IEEE 802.3 specifications, when using 1000 Mbps speed over

copper media, autonegotiation is not optional. In the absence of autonegotiation, (for example, while using Forced mode), link syncing between link partners may not happen and the link may not come up.

2. Set the adv-autoneg-cap parameter to 0.

# ndd -set /dev/ce adv-autoneg-cap 0

When you change any ndd link parameter, a message similar to the following appears:

xcvr addr:0x00 - link up 100 Mbps full duplex

Setting Parameters Using the ce.conf File

Specify the driver parameter properties for each device by creating a ce.conf file in the /platform/sun4u/kernel/drv directory. Use a ce.conf file when you need to set a particular parameter for a device in the system. The parameters you can set are the read and write parameters listed in “GigaSwift Ethernet Driver Parameter Values and Definitions” on page 38.

50 Sun GigaSwift Ethernet Adapter Installation and User’s Guide • August 2004

Note – Configuring the parameters by putting ndd commands in rcX.d scripts is

not supported.

The man pages for prtconf(1M) and driver.conf(4) include additional details. The next procedure shows an example of setting parameters in a ce.conf file.

● To access any man page, type the man command plus the name of the man page.

For example, to access man pages for prtconf(1M), type:

% man prtconf

▼ To Set Driver Parameters Using a ce.conf File

1. Obtain the hardware path names for the ce devices in the device tree. a. Check the /etc/driver_aliases file to identify the name associated with a

particular device:

# grep ce /etc/driver_aliases ce "pci108e,abba" ce "pci100b,35"

Note – ce "pci100b, 35" is used by the Sun GigaSwift Ethernet MMF/UTP

adapter.

b. Locate the path names and the associated instance numbers in the

/etc/path_to_inst file.

# grep ce /etc/path_to_inst "/pci@8,600000/network@1" 0 "ce"

■ In this example:

■ The first part within the double quotes specifies the hardware node name in

the device tree.

■ The number not enclosed in quotes is the instance number (shown in bold

italics).

■ The last part in double quotes is the driver name.

■ In the hardware node name, the last component after the last / character and

before the @ character is the device name.

Chapter 4 Configuring Driver Parameters 51

■ The path name before the last component is the parent name.

■ The number after the final @ character within quotes is the unit-address.

To identify a PCI device unambiguously in the ce.conf file, 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 this example:

■ parent = "/pci@8,600000"

■ unit-address = "1"

2. Set the parameters for the above devices in the /platform/sun4u/kernel/drv/ce.conf file.

In the following example, the adv_autoneg_cap and adv_1000fdx_cap parameters are set for all Sun GigaSwift Ethernet devices. See the driver.conf(4) man page for more information.

adv-autoneg-cap=0 adv-1000fdx-cap=0;

In the following example, the adv-autoneg-cap and adv-1000fdx-cap parameters are set for a single instance of the Sun GigaSwift Ethernet device.

name="pci100b,35" parent="/pci@8,600000" unit-address="1" adv-autoneg-cap=0 adv-100hdx-cap=0 adv-100fdx-cap=1 adv-1000fdx-cap=0 adv10hdx-cap=0 adv-10fdx-cap=0 adv-1000hdx-cap=0 adv-100T4-cap=0;

Note – If you omit the name=, parent=, and unit-address= definitions, the

settings become global to all Sun GigaSwift Ethernet instances.

3. Save the ce.conf file.

Usability Enhancements to the Driver

In older Ethernet device drivers, determining the link status for a driver required a two-step process:

First, you had to set the instance:

# ndd -set /dev/ce instance 2

52 Sun GigaSwift Ethernet Adapter Installation and User’s Guide • August 2004

Then you had to get the link status:

# ndd -get /dev/ce link_status 1

Starting in the Solaris 9 Operating System, this method of determining the link status is discouraged, and in some cases, it is removed completely as a driver feature.

The new improved approach moves all read-only parameters from the ndd options into kstat. This simplifies getting link status information by allowing you to do it with one simple command.

● To get the link status of a driver, type the following command:

# kstat ce:# | grep link_up link_up 0

Where # = instance. For more information about the kstat command, refer to the kstat man page.

CHAPTER

Configuring VLANs

This chapter explains VLANs in detail and provides configuration instructions and examples.

VLANs: Virtual Local Area Networks (VLANs) are commonly used to split up groups of network users into manageable broadcast domains, to create logical segmentation of workgroups, and to enforce security policies among each logical segment. With multiple VLANs on an adapter, a server with a single adapter can have a logical presence on multiple IP subnets. By default, 128 VLANs can be defined for each VLAN-aware adapter on your server. However, this number can be increased by changing the system parameters.

If your network does not require multiple VLANs, you can use the default configuration, in which case no further configuration is necessary.

■ “Overview of VLANs” on page 63

■ “Configuring VLANs” on page 66

Note – If you change any of the VLAN configuration parameters, you must reboot

the system before the changes take effect. If you make changes and do not reboot, you may experience configuration problems.

Overview of VLANs

VLANs enable you to split your physical LAN into logical subparts, providing an essential tool for increasing the efficiency and flexibility of your network.

VLAN 1 VLAN 2 VLAN 3

VLANs are commonly used to separate groups of network users into manageable broadcast domains, to create logical segmentation of workgroups, and to enforce security policies among each logical segment. Each defined VLAN behaves as its own separate network, with its traffic and broadcasts isolated from the others, increasing the bandwidth efficiency within each logical group.

Although VLANs are commonly used to create individual broadcast domains and/or separate IP subnets, it can be useful for a server to have a presence on more than one VLAN simultaneously. Several Sun products support multiple VLANs on a per port or per interface basis, allowing very flexible network configurations.

64 Sun GigaSwift Ethernet Adapter Installation and User’s Guide • August 2004

Engineering/ Software PC 5 Adapter Gigabit/Tagged (VLAN 1 & 2)

The physical LAN network consists of a switch, two servers, and five clients. The LAN is logically organized into three different VLANs, each representing a different IP subnet.

■ VLAN 1 is an IP subnet consisting of the Main Server, Client 3, and Client 5. This

represents an engineering group.

■ VLAN 2 includes the Main Server, Clients 1 and 2 by means of a shared media

segment, and Client 5. This is a software development group.

■ VLAN 3 includes the Main Server, the Accounting Server and Client 4. This is an

accounting group.

The Main Server is a high-use server that needs to be accessed from all VLANs and IP subnets. The server has a Sun GigaSwift Ethernet adapter installed. All three IP subnets are accessed by means of the single physical adapter interface. The server is attached to one of the SunSwitch’s Gigabit Ethernet ports, which is configured for VLANs 1, 2, and 3. Both the adapter and the connected SunSwitch™ port have tagging turned on. Because of the tagging VLAN capabilities of both devices, the sever is able to communicate on all three IP subnets in this network, but continues to maintain broadcast separation between all of them.

The Accounting Server is available to VLAN 3 only. It is isolated from all traffic on VLANs 1 and 2. The switch port connected to the server has tagging turned off.

Clients 1 and 2 are attached to a shared media hub that is then connected to the switch. They belong to VLAN 2 only, and are logically in the same IP subnet as the Main Server and Client 5. The switch port connected to this segment has tagging turned off.

Client 3 is a member of VLAN 1, and can communicate only with the Main Server and Client 5. Tagging is not enabled on Client 3’s switch port.

Client 4 is a member of VLAN 3, and can communicate only with the servers. Tagging is not enabled on Client 4’s switch port.

Client 5 is a member of both VLANs 1 and 2, and has a Sun GigaSwift Ethernet adapter installed. It is connected to switch port 10. Both the adapter and the switch port are configured for VLANs 1 and 2 and have tagging enabled.

VLAN tagging is only required to be enabled on switch ports that create trunk links to other VLAN-aware Ethernet switches, or on ports connected to tag-capable endstations, such as servers or workstations with VLAN-aware adapters.

Chapter 5 Configuring VLANs 65

Configuring VLANs

VLANs can be created according to various criteria, but each VLAN must be assigned a VLAN tag or VLAN ID (VID). The VID is a 12-bit identifier between 1 and 4094 that identifies a unique VLAN. For each network interface (ce0, ce1, ce2 and so on), 4094 possible VLAN IDs can be selected. Because IP subnets are commonly used, it is best to use IP subnets when setting up a VLAN network interface. This means that each VID assigned to a VLAN interface of a physical network interface will belong to different subnets.

Tagging an Ethernet frame requires the addition of a tag header to the frame. The header is inserted immediately following the Destination MAC address and the Source MAC address. The tag header consists of two bytes of Ethernet Tag Protocol Identifier (TPID, 0x8100) and two bytes of Tag Control Information (TCI). shows the Ethernet Tag Header format.

By default, a single VLAN is configured for every port, which groups all ports into the same broadcast domain, just as if there were no VLANs at all, VLAN tagging for the switch port turned off.

Note – If you configure a VLAN virtual device for an adapter, all traffic sent or

received by that adapter must be in VLAN-tagged format.

66 Sun GigaSwift Ethernet Adapter Installation and User’s Guide • August 2004

▼ To Configure Static VLANs

1. Create one hostname6.cenumber file for each VLAN that will be configured for each adapter on the server.

Use the following naming format that includes both the VID and the physical point of attachment (PPA):

VLAN logical PPA = 1000 * VID + Device PPA

ce123000 = 1000*123 + ce

This format limits the maximum number of PPAs (instances) you can configure to 1000 in the /etc/path_to_inst file.

For example, on a server with the Sun GigaSwift Ethernet adapter having an instance of 0, that belongs to a member of two VLANs, with VID 123 and 224, you would use ce123000 and ce224000, respectively, as the two VLAN PPAs.

2. Use the ifconfig(1M) to configure a VLAN virtual device, for example:

# ifconfig ce123000 plumb up # ifconfig ce224000 plumb up

The output of ifconfig -a on a system having VLAN devices ce123000 and ce224000:

Installing the Software Manually

This appendix describes how to install the driver software manually. It contains the following sections:

■ “Installing the Driver Software Manually” on page 69

■ “Verifying Patches” on page 74

Installing the Driver Software Manually

The Sun GigaSwift Ethernet Adapter CD contains the driver software required to operate the adapter. When you update your Solaris operating system, refer to the documentation that shipped with the Solaris Supplement CD-ROM for a listing of the available network drivers. Install the Sun GigaSwift Ethernet driver for your updated version of the Solaris operating system.

▼ To Install the Driver Software Manually

1. Become superuser.

2. Insert the Sun GigaSwift Ethernet Adapter CD into a CD-ROM drive that is connected to your system.

■ If your system is running Sun Enterprise Volume Manager™, it should

automatically mount the CD-ROM to the /cdrom/cdrom0 directory.

■ If your system is not running Volume Manager, mount the CD-ROM as follows:

# mkdir /cdrom # mkdir /cdrom/cdrom0 # mount -F hsfs -o ro /dev/dsk/c0t6d0s2 /cdrom/cdrom0

You will see the following files and directories in the

/cdrom/sun_gigaswift_ethernet_driver directory or the /cdrom/cdrom0 directory, depending on how you mounted the CD-ROM.

Note – If you intend to use VLAN, you must install VLAN packages when you

install the software packages.

3. Determine if the ce and vlan drivers are installed on the system:

■ If you are using a Solaris SPARC system:

#/usr/bin/pkginfo SUNWced SUNWcedx SUNWvld SUNWvldx system SUNWced Sun GigaSwift Ethernet Adapter (32-bit Driver) system SUNWcedx Sun GigaSwift Ethernet Adapter (64-bit Driver) system SUNWvld Sun Ethernet Vlan Utility Routines system SUNWvldx Sun Ethernet Vlan Utility Routines (64-bit)

■ If you are using a Solaris x86 system:

#/usr/bin/pkginfo SUNWced SUNWvld system SUNWced Sun GigaSwift Ethernet Adapter system SUNWvld Sun GigaSwift Ethernet Adapter

■ If the output of the command is similar to the appropriate example in Step 3, skip

to Step 6.

Appendix A Installing the Software Manually 71

■ If nothing is reported back on SUNWced or SUNWcedx, then proceed to Step 4 and

select SUNWcea, SUNWceax, SUNWced.u, SUNWcedx.u, SUNWcedu, and SUNWcem (if present).

■ If nothing is reported back for SUNWvld or SUNWvldx, then proceed to Step 4 and

select SUNWvld, SUNWvldx, and SUNWvldu packages.

■ If nothing is reported back, then proceed to Step 4 and select "all" packages.

4. Install the software packages by typing the following at the command line, replacing the OS_VER with your version of the Solaris operating system:

■ If your system is running Solaris 7 or 8 software type the following:

# /usr/sbin/pkgadd -d /cdrom/cdrom0/GigaSwiftEthernet/Solaris_OS_VER/Packages/

Where OS_VER is 7 or 8 For example, if your system is running the Solaris 8 operating system, you would

type the following:

# /usr/sbin/pkgadd -d /cdrom/cdrom0/GigaSwiftEthernet/Solaris_8/Packages/

■ If your system is running Solaris 9 SPARC software type the following:

# /usr/sbin/pkgadd -d /cdrom/cdrom0/GigaSwiftEthernet/Solaris_9/Sparc/Packages/

72 Sun GigaSwift Ethernet Adapter Installation and User’s Guide • August 2004

■ If your system is running Solaris 9 x86 software type the following:

# pkgadd -d /Solaris_9/i386/Packages/

A menu similar to the following displays:

The following packages are available: 1 SUNWcea Sun GigaSwift Ethernet Adapter Driver 32 bit adb Macros (sparc) 1.0,REV=2001.05.04 2 SUNWceax Sun GigaSwift Ethernet Adapter Driver 64 bit adb Macros (sparc) 1.0,REV=2001.05.04 3 SUNWced.u Sun GigaSwift Ethernet Adapter (32-bit Driver) (sparc.sun4u) 1.0,REV=2001.05.04 4 SUNWcedu Sun GigaSwift Ethernet Adapter Driver Headers (sparc) 1.0,REV=2001.05.04 5 SUNWcedx.u Sun GigaSwift Ethernet Adapter (64-bit Driver) (sparc.sun4u) 1.0,REV=2001.05.04 6 SUNWcem Sun GigaSwift Ethernet Adapter Driver Man Pages (sparc) 1.0,REV=2001.05.04 7 SUNWvld Sun Ethernet Vlan Utility Routines (sparc) 1.0,REV=2001.05.04 8 SUNWvldu Sun Ethernet Vlan Utility Headers (sparc) 1.0,REV=2001.05.04 9 SUNWvldx Sun Ethernet Vlan Utility Routines (64-bit) (sparc) 1.0,REV=2001.05.04

Select package(s) you wish to process (or ’all’ to process all packages). (default: all) [?,??,q]:

5. Select the packages you want to install:

■ Press Return or type all to accept the default and install all packages (if neither

the GigaSwfit Ethernet Driver nor VLAN Utility packages are installed).

■ Type the numbers of all but the optional packages if you prefer not to install

them. See

TABLE A-1 to identify the optional packages.

6. If the packages are already installed, verify the patch version.

See the following section.

Appendix A Installing the Software Manually 73

Verifying Patches

Verify whether your system has the needed patches for your version of the Solaris Operating System to ensure that you do not need to add patches.

Note – If patches meet the requirements, nothing needs to be installed on the install

system.

TABLE A-2 lists and describes the patch versions:

TABLE A-2 Patch Versions

Table describes the patch versions.

▼ To Install Patches

1. Determine the version of the Solaris Operating System your system is running:

2. Verify patch versions for the GigaSwift Etnernet driver:

74 Sun GigaSwift Ethernet Adapter Installation and User’s Guide • August 2004

■ To verify patches for the Solaris 8 Operating System, type the following:

# showrev -p | grep 111883

The patch version should be -24 or greater.

■ To verify patches for the Solaris 9 SPARC Operating System, type the following:

# showrev -p | grep 112817

The patch version should be -17 or greater.

■ To verify patches for the Solaris 9 x86 Operating System, type the following:

# showrev -p | grep 117714

The patch version should be -01 or greater.

3. If the patch is not present or the patch version is not correct, install the correct patch:

# cd /cdrom/cdrom0 # patchadd GigaSwiftEthernet/OS/Patches/patch-id

■ If your system is running Solaris 7 or 8 software type the following:

# patchadd GigaSwiftEthernet/OS/Patches/patch-id

Where: OS_VER = Solaris 7 or Solaris 8 patch-id = 112327-18 for Solaris 7 or 11883-24 for Solaris 8

■ If your system is running Solaris 9 SPARC software type the following:

# cd /cdrom/cdrom0 # patchadd GigaSwiftEthernet/Solaris_9/sparc/Patches/112817-17

Appendix A Installing the Software Manually 75

■ If your system is running Solaris 9 x86 software type the following:

# cd /cdrom/cdrom0 # patchadd GigaSwiftEthernet/Solaris_9/i386/Patches/117714-01

▼ To Install a Sun VLAN Utility Patch

Note – The VLAN Utility is only supported in Solaris 8 and Solaris 9 software.

1. Determine the version of the Solaris Operating System your system is running:

2. Verify patch versions for the VLAN utility software:
