▼ 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.

14 Sun GigaSwift Ethernet Adapter Installation and User’s Guide • February 2003

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

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

You may 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 again.

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 cables.

■ For the Sun GigaSwift Ethernet MMF PCI Bus card, connect the fiber optic cable

(850nm, SC) to the PCI adapter and to a fiber optic Ethernet network.

Chapter 2 Installing the Adapter 15

FIGURE 2-2 Cat-5 Twisted-Pair Cable

▼ To Verify the 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
Solaris Handbook for Sun Peripherals manual or your Solaris documentation for the
detailed instructions.

Note – Verification is not required if your system supports dynamic reconfiguration

(DR).

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.

If the card is properly installed and the cables are properly connected to a
compatible network, you will see the following message:

xcvr addr:0x00 - link up 1000 Mbps full duplex

16 Sun GigaSwift Ethernet Adapter Installation and User’s Guide • February 2003

2. List the network devices on your system.

ok show-nets

Use the show-nets command to list the system devices. You should see the full
path name of the network devices, similar to the Ultra 30 system example below. In
this example, the network@4 device is the Sun GigaSwift Ethernet adapter and the

network@1,1 is the onboard Ethernet device.

ok show-nets
a) /pci@1f,2000/pci@1/network@4
b) /pci@1f,4000/network@1,1
q) NO SELECTION
Enter Selection, q to quit: q

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

and, if necessary, reinstall the adapter.

3. View the device that you installed.

Using the previous example, type:

ok cd /pci@1f,0/pci@1/network@4

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

/pci@1f,0/pci@1/network@4. While your device path may be different, it will be

similar. You will need this information to make changes to the ce.conf file. See
“Setting Parameters Using the ce.conf File” on page 51.

Chapter 2 Installing the Adapter 17

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

It might be difficult to tell if the devices on your network are GigaSwift Ethernet
devices or other network interface cards. The.properties command displays the
specific information about the installed adapter.

At the ok prompt, use the .properties command to make sure that the device you
just installed is connected to the network. Your output may look different from the
following example:

The phy-type will have its value assigned as follows:

Media type phy-type

Fiber pcs
Copper mif

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

local-mac-address of your device at this time. See “Setting the local-mac­address Property” on page 19 for more information.

Setting the local-mac-address Property

Note – Setting the local-mac-address property is only required if you will be

booting from the network.

The network interface of the Sun GigaSwift Ethernet adapter has been assigned a
unique media access control (MAC) address that represents the 48-bit Ethernet
address for that interface. The OpenBoot firmware reports this MAC address via the
local-mac-address property in the device nodes corresponding to the network
interface.

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

The device driver, or any other adapter utility, can use the network device’s MAC
address (local-mac-address) while configuring it. In the Solaris operating
environment, you can use the MAC address when booting over the network.

The mac-address property of the network device specifies the network address
(system-wide or local-mac-address) used for booting the system. 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

Chapter 2 Installing the Adapter 19

▼ To Set the GigaSwift Ethernet Device Primary Boot Device

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

1. List the network devices on your system.

ok show-nets
a) /pci@1f,2000/pci@1/network@4
b) /pci@1f,4000/network@1,1
q) NO SELECTION
Enter Selection, q to quit: q

2. Set the Sun GigaSwift Ethernet device to be your default boot device, type:

ok setenv boot-device /pci@1f,2000/pci@1/network@4

Note that the correct command has a space rather than = between boot-device
and /pci@1f,2000/pci@1/network@4.

Rebooting the System

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

ok boot -r

20 Sun GigaSwift Ethernet Adapter Installation and User’s Guide • February 2003

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 (1) connecting
the attachment point and (2) configuring its occupant. In most cases, the
cfgadm(1M) command can perform both steps at once.

▼ To Install an Adapter in a Dynamic

Reconfiguration System

1. Verify that the selected board slot is ready for the adapter.

# cfgadm

The states and conditions should be:

Receptacle state—Empty
Occupant state—Unconfigured
Condition—Unknown

Or:

Receptacle state—Disconnected
Occupant state—Unconfigured
Condition—Unknown

Chapter 2 Installing the Adapter 21

2. If the status of the slot is not “empty” or “disconnected”, type:

# cfgadm -c disconnect sysctrl#:slot#

where the sysctrl# = 0 for the Enterprise 10000 and slot#= the slot available for the
adapter. For example, if you were installing the adapter into slot #3 on an Enterprise
10000, you would type the following:

# cfgadm -c disconnect sysctrl0:3

3. Physically insert the adapter into the slot and look for an acknowledgement on
the console, such as, “name board inserted into slot3.”

After the adapter is inserted, the states and conditions should become:

Receptacle state—Disconnected
Occupant state—Unconfigured
Condition—Unknown

Any other states or conditions should be considered an error.

4. Connect any peripheral cables and interface modules to the adapter.

5. Connect the cables to the card and to an Ethernet network.

6. Configure the adapter with the following command:

# cfgadm -v -c configure sysctrl#:slot#

This command should both connect and configure the receptacle. Verify with the
cfgadm command.

The states and conditions for a connected and configured attachment point should
be:

Receptacle state—Connected
Occupant state—Configured
Condition—OK

22 Sun GigaSwift Ethernet Adapter Installation and User’s Guide • February 2003

Now the system is also aware of the usable devices which reside on the adapter and
all devices may be mounted or configured to be used.

If the command fails to connect and configure the adapter and slot (the status should
be shown as “configured” and “ok”), do the connection and configuration as
separate steps:

a. Connect the adapter and slot:

# cfgadm -v -c connect sysctrl#:slot#

The states and conditions for a connected attachment point should be:

Receptacle state—Connected
Occupant state—Unconfigured
Condition—OK

Now the system is aware of the adapter, but not the usable devices which reside
on the adapter. Temperature is monitored and power and cooling affect the
attachment point condition.

b. Configure the adapter and slot:

# cfgadm -v -c configure sysctrl#:slot#

The states and conditions for a configured attachment point should be:

Receptacle state—Connected
Occupant state—Configured
Condition—OK

Now the system is also aware of the usable devices which reside on the adapter and
all devices may be mounted or configured to be used.

7. Reconfigure the devices on the adapter

# drvconfig; devlinks; disks; ports; tapes;

The console should now display a list of devices and their addresses.

Chapter 2 Installing the Adapter 23

CHAPTER

3

Network Configuration

This chapter describes how to edit the network host files after the adapter has been
installed on your system. The 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 Environment Over a GigaSwift Ethernet

Network” on page 29

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@1f,4000/network@4"

In the example above, 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. While your device path and instance may be

different, it will be similar. You will need this information to make changes to the
ce.conf file. See “Setting Parameters Using the ce.conf File” on page 51.

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

0

"ce"

25

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’s IP
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 set-up that will remain 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 for the

appropriate ce interface.

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

/etc/hosts file.

■ The host name should 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

26 Sun GigaSwift Ethernet Adapter Installation and User’s Guide • February 2003

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 1.0 Update 1 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 operating environment does 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 will be:

/export/root/client_name

Chapter 3 Network Configuration 27

2. Insert the Sun GigaSwift Ethernet Driver 1.0 Update 1 CD into the server’s CD-ROM
drive.

The CD should automatically mount to the /cdrom/cdrom0 directory. If the CD did
not get mounted to this directory, refer to “Installing the Driver Software” on page 9
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.

You will need to 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 /

4. Eject the Sun GigaSwift Ethernet Driver 1.0 Update 1 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 in the diskless client’s root directory.

You will need to 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. Be sure to 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

28 Sun GigaSwift Ethernet Adapter Installation and User’s Guide • February 2003

Installing the Solaris Operating
Environment Over a GigaSwift Ethernet
Network

The Solaris Advanced Installation Guide describes the full procedure for installing the
Solaris operating environment over the network. The procedure below 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.

Before you can install the Solaris operating environment 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 1.0 Update 1 CD.

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

installing the Solaris operating environment over the network.

▼ To Install the Solaris Environment Over a

GigaSwift Ethernet Network

1. Prepare the install server and client system to install the Solaris operating
environment 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.

Chapter 3 Network Configuration 29

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 the example above, the root directory for the Solaris 7 client is /netinstall.In
Step 4, 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 1.0 Update 1 CD into the install server’s CD­ROM drive.

The CD should automatically mount to the /cdrom/cdrom0 directory. If the CD did
not get mounted to this directory, refer to “Installing the Driver Software” on page 9
for mounting instructions.

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 – The directory paths for these files might change in future Solaris releases. If

the commands above do not work correctly, refer to the documentation that shipped
with your version of the Solaris operating environment.

5. Eject the Sun GigaSwift Ethernet Driver 1.0 Update 1 CD from the CD-ROM drive.

Note – Perform the following steps on the client system.

30 Sun GigaSwift Ethernet Adapter Installation and User’s Guide • February 2003

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@1f,2000/pci@1/network@4
b) /pci@1f,4000/network@1,1
q) NO SELECTION
Enter Selection, q to quit: q

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

Following are several examples, which show the different options available:

■ Booting in Auto-Negotiated mode:

ok boot:link-param, -v

■ Booting in Auto-Negotiated 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, hence the link will be established within
this range of capabilities, depending on the configuration of the link partner.

Chapter 3 Network Configuration 31

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

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

■ Booting in non-Auto-Negotiated 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 link to be successfully established the link partner must be configured to

1000 Mbps half duplex link-clock slave.

9. Proceed with the Solaris operating environment installation.

Refer to the Solaris Advanced Installation Guide for more information about installing
the Solaris operating environment over the network.

10. After installing the Solaris operating environment, 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.

Refer to “Installing the Driver Software” on page 9 for instructions on installing
the required software packages.

32 Sun GigaSwift Ethernet Adapter Installation and User’s Guide • February 2003

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

The Sun GigaSwift Ethernet adapter can be linked up either with Auto-Negotiation
enabled or disabled. When link-up is attempted with Auto-Negotiation 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
the device and its link partner. Attempting to link-up with Auto-Negotiation
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,

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 Device Driver Parameters” on page 37

■ “Setting ce Driver Parameters” on page 47

■ “Usability Enhancements to the Driver” on page 53

■ “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 50. 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 a forced mode of operation.

37

Note – The syntax for the Sun GigaSwift Ethernet driver parameters has changed.

The syntax for parameters formerly included an underscore, for example,

adv_autoneg_cap. The current syntax uses a dash instead, for example,
adv-autoneg-cap. During the transition phase, either format is acceptable.

However, be sure to check the Platform Notes: Sun GigaSwift Ethernet Device Driver in
your version of the Solaris operating environment.

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

it, it will revert back to 0.

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

NOTICE: Last setting will leave ce1 with no link capabilities.
WARNING: ce1: 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. On the other hand, the ce device is capable of sourcing flow control
frames, 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.

40 Sun GigaSwift Ethernet Adapter Installation and User’s Guide • February 2003

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 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.

Chapter 4 Configuring Driver Parameters 41

Gigabit Link Clock Mastership Controls

The concept of link clock mastership introduced with one gigabit twisted-pair
technology. This concept requires one side of the link to be the master that provides
the link clock and the other to be 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. Those parameters are as
follows.

TABLE 4-4 Forced Mode Parameter

Parameter Description

master-cfg-enable Determines whether or not during the auto-negotiation process

the link clock mastership is setup automatically.

master-cfg-value If the master-cfg-enable parameter is set then the mastership

is not setup automatically but is dependant on the value of
master-cfg-value.Ifthemaster-cfg-value is set then the
physical layer expects the local device to be the link master. If it is
not set then it expects the link partner to be the master.
If Auto-negotiation is not enabled then the value of

master-cfg-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 it’s not set then it expects the
link partner to the master.

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 a driver 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 to reduce collisions.

42 Sun GigaSwift Ethernet Adapter Installation and User’s Guide • February 2003

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

1

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 machines seem to be slow in accessing the network, increase the values of
ipg1 and ipg2 to match the longer IPGs of other machines.

Chapter 4 Configuring Driver Parameters 43

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=8)

rx-intr-time 0 to 524287 Interrupt after 4.5 microseconds ticks have elapsed since

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

44 Sun GigaSwift Ethernet Adapter Installation and User’s Guide • February 2003

Random Early Drop Parameters

TABLE 4-8 describes the RX random early detection 8-bit vectors, which allows 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 less
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)

red-dv6to8k 0 to 255 Random early detection and packet drop vectors for

when FIFO threshold is greater than 6,144 bytes and
less than 8,192 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)

red-dv8to10k 0 to 255 Random early detection and packet drop vectors for

when FIFO threshold is greater than 8,192 bytes and
less than 10,240 bytes. Probability of drop can be
programmed on a 12.5 percent granularity. For
example, if bit 1 and 6 are set the second and seventh
packets 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
less than 12,288 bytes. Probability of drop can be
programmed on a 12.5 percent granularity. If bit 2, 4
and 6 are set then the third, fifth and seventh packets
out of every eight will be dropped in this region.
(Default=0)

Chapter 4 Configuring Driver Parameters 45

PCI Bus Interface Parameters

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

Parameter Description

tx-dma-weight Determine the multiplication factor for granting credit to the TX

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

are power of 2 extra weighting, on that traffic. For example
of tx-dma-weight = 0 and rx-dma-weight = 3 then as long as
RX traffic is continuously arriving its priority will be 8 times
greater than TX to access the PCI

rx-dma-weight Determine 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 Allows the infinite burst capability to be utilized. When this is in

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

means no extra weighting. The other values

disable-64bit Switches off 64 bit capability of the adapter. In some cases, it is

useful to switch off this feature.
Values are 0 or 1. (Default=0, which enables 64 bit capability)

46 Sun GigaSwift Ethernet Adapter Installation and User’s Guide • February 2003

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.

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, which 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.

Chapter 4 Configuring Driver Parameters 47

▼ 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@1f,2000/pci@1/network@0"
"/pci@1f,2000/pci@2/network@0"
"/pci@1f,2000/pci@4/network@0"

In the example above, the three GigaSwift Ethernet instances are from the installed
adapters. The instance numbers are in bold italics for clarity.

2. Use the instance number to select the device.

# ndd -set /dev/ce instance instance#

The device remains selected until you change the selection.

2

"ce"

1

"ce"

0

"ce"

Noninteractive and Interactive Modes

You can use the ndd utility in two modes:

■ Noninteractive

■ Interactive

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.)

48 Sun GigaSwift Ethernet Adapter Installation and User’s Guide • February 2003

Using 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 it to the
parameter:

# ndd -set /dev/ce parameter value

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

xcvr addr: 0x00 - 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, 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/ce parameter

Using the ndd Utility in Interactive Mode

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

below.

The ndd utility then prompts you for the name of the parameter:

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

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

TABLE 4-1 through TABLE 4-11).

Chapter 4 Configuring Driver Parameters 49

● To list all the parameters supported by the ce driver, type ndd /dev/ce.

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.

50 Sun GigaSwift Ethernet Adapter Installation and User’s Guide • February 2003

▼ 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-1000hdx-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

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 on a per-device basis 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 set
are read and write parameters that are listed in “Driver Parameter Values and
Definitions” on page 38.

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

not supported.

Chapter 4 Configuring Driver Parameters 51

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 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"

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

/etc/path_to_inst file.

# grep ce /etc/path_to_inst
"/pci@9,700000/network@2"
"/pci@8,700000/pci@5/network@0"
"/pci@8,700000/pci@5/network@1"

0

"ce"

3

"ce"

4

"ce"

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

the @ character is the device name.

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

■ The number after the final @ character within quotes is referred to as 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 the first line in the previous example:

■ parent =“pci@9”

■ unit-address =“2”

In the second line in the previous example:

■ parent =“pci@5”

52 Sun GigaSwift Ethernet Adapter Installation and User’s Guide • February 2003

■ unit-address =“0”

In the third line in the previous example:

■ parent =“pci@5”

■ 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="pci108e,abba" parent="pci@9,600000" unit-address="2"
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 – The difference between setting parameters for all Sun GigaSwift Ethernet

devices and setting parameters for a single instance of the device depends on
whether you include the name=, parent=, and unit-address=. If you omit these
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/hme instance 2

Chapter 4 Configuring Driver Parameters 53

■ Then you had to get the link status:

# ndd -get /dev/hme link-status
1

Starting with the Sun GigaSwift Ethernet adapter in the Solarlis 9 operating
environment 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:n | grep link_up
link_up 0

where n=instance.
For more information about the kstat command, refer the kstat man page

These statistics are part of the statistics presented by the netstat -k command.

CHAPTER

5

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.

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

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

An Overview of VLANs

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

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.

63

Although VLANs are commonly used to create individual broadcast domains and/
or separate IP subnets, it is sometimes 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.

FIGURE 5-1 Example of Servers Supporting Multiple VLANs with Tagging Adapters

The example network has the following features:

■ 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 via 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.

64 Sun GigaSwift Ethernet Adapter Installation and User’s Guide • February 2003

■ The Main Server is a high-use server that needs to be accessed from all VLANs

and IP subnets. The server has an Sun GigaSwift Ethernet adapter installed. All
three IP subnets are accessed via 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.

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. Only 512 unique IDs can be
used simultaneously. 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.

Chapter 5 Configuring VLANs 65

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).

VID

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.

▼ To Configure Static VLANs

1. Create one hostname6.cenum file for each VLAN which will be configured for each
adapter on the server, using 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.

66 Sun GigaSwift Ethernet Adapter Installation and User’s Guide • February 2003

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:

# ifconfig -a
lo0: flags=1000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4> mtu 8232 index 1
inet 127.0.0.1 netmask ff000000
hme0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
inet 129.144.131.91 netmask ffffff00 broadcast 129.144.131.255
ether 8:0:20:a4:4f:b8
ce123000: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 3
inet 199.199.123.3 netmask ffffff00 broadcast 199.199.123.255
ether 8:0:20:a4:4f:b8
ce224000: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 4
inet 199.199.224.3 netmask ffffff00 broadcast 199.199.224.225
ether 8:0:20:a4:4f:b8

3. On the switch, set VLAN tagging and set VLAN ports to coincide with the VLANs
you’ve set up on the server. Using the examples in Step 2, you would set up VLAN
ports 123 and 224 on the switch.

Refer to the documentation that came with your switch for specific instructions for
setting VLAN tagging and ports.

Diagnostic Software and
Troubleshooting Issues

This appendix provides an overview of the SunVTS diagnostic application and
instructions for testing the adapter using the onboard FCode self-test. There is also a
section outlining some common troubleshooting issues. This appendix contains the
following sections:

■ “SunVTS Diagnostic Software” on page 73

■ “Using the OpenBoot PROM FCode Self-Test” on page 74

■ “Troubleshooting Issues” on page 76

SunVTS Diagnostic Software

The SunVTS software executes multiple diagnostic hardware tests from a single user
interface and is used to verify the configuration and functionality of most hardware
controllers and devices. The SunVTS software operates primarily from a graphical
user interface, enabling test parameters to be set quickly and easily while a
diagnostic test operation is being performed.

The nettest and the netlbtest check all the networking interfaces on a system,
including the Sun GigaSwift Ethernet adapter. Refer to the SunVTS User’s Guide for
more information on how to run the nettest diagnostic test.

Note – To use the nettest or netlbtest diagnostic, you must have the SunVTS

software installed on your system. Refer to the Solaris Sun Hardware Platform Guide,
which was shipped with the Solaris Supplement CD, for instructions on how to install
the SunVTS software.

73

Using the OpenBoot PROM FCode Self­Test

The following tests are available to help identify problems with the adapter if the
system does not boot.

You can invoke the FCode self-test diagnostics by using the OpenBoot user interface
test or test-all commands. If you encounter an error while running diagnostics,
appropriate messages will be displayed. Refer to the appropriate OpenBoot Command
Reference Manual for more information on the test and test-all commands.

The FCode self-test exercises most functionality sub-section by sub-section and
ensures the following:

■ Connectivity during adapter card installation

■ Verification that all components required for a system boot are functional

▼ Running the Ethernet FCode Self-Test Diagnostic

To run the Ethernet diagnostics, you must first bring the system to a stop at the
OpenBoot prompt after issuing a reset. If you do not reset the system, the diagnostic
tests might cause the system to hang.

For more information about the OpenBoot commands in this section, refer to the
appropriate OpenBoot Command Reference Manual.

1. Shut down the system.

Use the standard shutdown procedures described in the Solaris Handbook for Sun
Peripherals.

2. At the ok prompt, set the auto-boot? configuration variable to false.

ok setenv auto-boot? false

3. Reset the system.

ok reset-all

74 Sun GigaSwift Ethernet Adapter Installation and User’s Guide • February 2003

4. Type show-nets to display the list of devices.

You should see a list of devices, similar to the example below, specific to the adapter:

ok show-nets
a) /pci@1f,0/pci@1/network@4
b) /pci@1f,0/pci@1,1/network@1,1
q) NO SELECTION
Enter Selection, q to quit:

5. Type the following to run the self-test using the test command:

ok test device path

The following tests are run when the test command is executed:

■ ce register test (happens only when diag-switch? is true)

■ internal loopback test

■ link up/down test

If the test passes, you see these messages:

ok test /pci@1f,0/pci@1/network@4
ce register test --- succeeded.
Internal loopback test -- succeeded.
Link is -- up

If the card is not connected to a network, you see the following messages:

ok test /pci@1f,0/pci@1/network@4
ce register test --- succeeded.
Internal loopback test -- succeeded.
Link is -- down
ok

6. After testing the adapter, type the following to return the OpenBoot PROM to
standard operating mode:

ok setenv diag-switch? false

Appendix B Diagnostic Software and Troubleshooting Issues 75

7. Set the auto-boot? configuration parameter to true.

ok setenv auto-boot? true

8. Reset and reboot the system.

or other pre- or non-IEEE 802.3z standard compliant network equipment. If you
experience difficulties with noncompliant equipment, set the adapter and switch
autonegotiation properties to off and try to configure the interface manually.
