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 – If you have a Sun Enterprise system that supports dynamic reconfiguration
(DR), refer to the Sun Enterprise Dynamic Reconfiguration User’s Guide and your
system’s documentation for further information about dynamic reconfiguration. DR
is not supported in the Solaris x86 operating system.
Using the Installation Script
The Sun 10-Gigabit Ethernet CD provides automated installation for the Sun 10-
Gigabit Ethernet PCI-X driver software. In most cases, you can use the following
procedure and execute the installation script. If you have any problems, see
Appendix C for manual installation procedures.
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 9 or 10 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 installed version, the script exits with an appropriate message.
▼ To Install the Software Using the Installation
Script
1. At the system console, become superuser (root).
2. Insert the Sun 10-Gigabit 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/cdrom0directory.
▼ If your system is not running Sun Enterprise Volume Manager, mount the CD-
ROM as follows:
# mount -F hsfs -o ro /dev/dsk/c0t6d0s2 /cdrom/cdrom0
Note – If you are installing the software from the download site, follow the online
download instructions.
3. Change to the directory were the installation script resides:
# cd /media-path/
where:
▼
media-path = /cdrom/cdrom0, if you are installing from the CD-ROM.
▼
unzipped 10-Gigabit-path/Sun_10-Gigabit_Ethernet_Driver, if you
downloaded the driver from the Sun download center.
4. Execute the installation script:
# ./install
Note – After the installation script runs, you see a summary of the software package
or patch that was installed. You can also find a log of the installation in /var/tmp.
The log file information is displayed when the installation completes unless the
software meets or exceeds the required package or patch level.
You’ll see the following output:

Configuring the Network Host Files
After installing the driver software, you must create a hostname.ixgenumber file
where number = the instance number of the ixgeinterface.) 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/hostsfile.
Caution – Ensure that the optical transceiver is correctly seated before configuring
the interface.
1. At the command line, use the grepcommand to search the /etc/path_to_inst
file for ixgeinterfaces.
# grep ixge /etc/path_to_inst
"/pci@9,600000/ethernet@1" 0 "ixge"
In the example above, the device instance is from a Sun 10-Gigabit Ethernet PCI-X
adapter. For clarity, the instance number is in bold italics.
2. Use the ifconfigcommand to set up the adapter’s ixgeinterface.
Use the ifconfigcommand 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 ixge0 plumb ip-address up
Caution – If the optical transceiver is unplugged after the interface has been
configured using the ifconfigcommand, you must unconfigure and reconfigure
the interface.
On Solaris operating systems, use the following commands to unconfigure and
reconfigure the interface:
# ifconfig ixge0 down
# ifconfig ixge0 unplumb
# ifconfig ixge0 plumb ip-address up

On Linux operating systems, use the following commands:
ifconfig ethnumber down
ifconfig ethnumber up
Where number corresponds to the device instance of the Sun 10-Gigabit Ethernet
PCI-X adapter you plan to configure.
Refer to the ifconfig(1M) man page and the Solaris or Linux documentation for
more information.
▼ If you want a setup that remains the same after you reboot, create an
/etc/hostname.ixgenumber file, where number corresponds to the instance
number of the ixgeinterface you plan to use.
To use the adapter’s ixgeinterface in the Step 1 example, create an
/etc/hostname.ixge0file, where 0is the number of the ixgeinterface. If the
instance number were 1, the filename would be
/etc/hostname.ixge1.
▼ Do not create an /etc/hostname.ixgenumber file for a Sun 10-Gigabit Ethernet
adapter interface you plan to leave unused.
▼ The /etc/hostname.ixgenumber file must contain the hostname and IP address
for the appropriate ixgeinterface.
▼ The host name and IP address must be listed in the /etc/hostsfile.
▼ The host name must be different from any other host name of any other interface,
for example: /etc/hostname.ixge0and /etc/hostname.ixge1cannot share
the same host name.
The following example shows the /etc/hostname.ixgenumber file required for a
system called zardozthat has a Sun 10-Gigabit Ethernet adapter (zardoz-11).
# cat /etc/hostname.hme0
zardoz
# cat /etc/hostname.ixge0
zardoz-11

For example:
# cat /etc/hosts
#
# Internet host table
#

10-Gigabit Ethernet Device Driver
Parameters
The ixgedevice driver controls the Sun 10-Gigabit Ethernet PCI-X adapter. The
ixgedriver is attached to the UNIX pciname property pci8086,1048for the Sun
10-Gigabit Ethernet PCI-X adapter (8086is the vendor ID and 1048is the PCI
device ID).
You can manually configure the ixgedevice driver parameters to customize each
Sun 10-Gigabit Ethernet adapter device in your system. This section provides an
overview of the capabilities of the 10-Gigabit Ethernet driver used in the adapter,
lists the available ixgedevice driver parameters, and describes how to configure
these parameters.

Flow Control Parameters
The ixgedevice sources (transmits) and terminates (receives) pause frames
conforming to the IEEE 802.3x Frame Based Link Level Flow Control Protocol. In
response to received flow control frames, the ixgedevice can slow down its
transmit rate. The ixgedevice 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.

▼ To Configure Jumbo Frames in a Linux
Environment
1. Ensure that the ixgesoftware is installed.
2. Plumb the Sun 10-Gigabit Ethernet PCI-X interface:
# modprobe ixge
# ifconfig eth2 xxx.xxx.xx.xxx up
# ifconfig eth2 mtu 8170
where xxx.xxx.xx.xxx = the IP address of the interface.
Setting ixgeDriver Parameters
You can set the ixgedevice driver parameters in two ways:
▼ Using the nddutility
▼ Using the ixge.conffile
If you use the nddutility, 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/ixge.conffile and add parameter values to this
file when you need to set a particular parameter for a device in the system.
Setting Parameters Using the nddUtility
Use the nddutility to configure parameters that are valid until you reboot the
system. The nddutility supports any networking driver that implements the Data
Link Provider Interface (DLPI).
The following sections describe how you can use the ixgedriver and the nddutility
to modify (with the -setoption) or display (without the -setoption) the
parameters for each ixgedevice.
Chapter 3 Configuring Driver Parameters
Download from Www.Somanuals.com. All Manuals Search And Download.
23
▼ To Specify Device Instances for the nddUtility
Before you use the nddutility to get or set a parameter for a ixgedevice, you must
specify the device instance for the utility.
1. Check the /etc/path_to_instfile to identify the instance associated with a
particular device.
# grep ixge /etc/path_to_inst
"/pci@9,600000/ethernet@1" 0 "ixge"
In this example, the 10-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/ixge instancenumber
The device remains selected until you change the selection.
Noninteractive and Interactive Modes
You can use the nddutility 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.
▼ To Use the nddUtility in Noninteractive Mode
This section describes how to modify and display parameter values.
24
Sun 10-Gigabit Ethernet PCI-X Adapter Installation and User’s Guide • December 2005
Download from Www.Somanuals.com. All Manuals Search And Download.
▼ To modify a parameter value, use the -setoption.
If you invoke the nddutility with the -setoption, the utility passes value, which
must be specified, down to the named /dev/ixgedriver instance, and assigns the
value to the parameter:
# ndd -set /dev/ixge parameter value
When you change any parameter, a message similar to the following appears:
ixge0: xcvr addr:0x01 - link up 10000 Mbps full duplex
▼ To display the value of a parameter, specify the parameter name and omit the
value.
When you omit the -setoption, the utility queries the named driver instance,
retrieves the value associated with the specified parameter, and prints it:
# ndd /dev/ixge parameter
▼ To Use the nddUtility in Interactive Mode
▼ To modify a parameter value in interactive mode, specify ndd /dev/ixge:
name to get/set? (Enter the parameter name or ? to view all
parameters)
After you enter the parameter name, the nddutility prompts you for the parameter
value (see TABLE 3-1 through TABLE 3-6).

Note – By default, autonegotiation is set to off. This adapter operates only at full-
duplex.
Specify the driver parameter properties for each device by creating a ixge.conffile
in the /platform/sun4u/kernel/drvdirectory. Use a ixge.conffile 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 “10-Gigabit Ethernet Driver
Parameter Values and Definitions” on page 20.
Note – Configuring the parameters by putting nddcommands in rcX.dscripts 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 ixge.conffile.
▼ To access any man page, type the mancommand 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 ixge.conf
File
1. Obtain the hardware path names for the ixgedevices in the device tree.
a. Check the /etc/driver_aliasesfile to identify the name associated with a
particular device:
# grep ixge /etc/driver_aliases
ixge "pci8086,1048.108e.7036"
Note – ixge "pci8086,1048.108e.7036" is used by the Sun 10-Gigabit Ethernet
adapter.
b. Locate the path names and the associated instance numbers in the
/etc/path_to_instfile.
# grep ixge /etc/path_to_inst
"/pci@9,600000/ethernet@1" 0 "ixge"

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.
▼
▼
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 ixge.conffile, use the name, parent
name, and the unit-address for the device. Refer to the pci(4) man page for more
information about the PCI device specification.
2. Set the parameters for the above devices in the
/platform/sun4u/kernel/drv/ixge.conffile.
In the following example, the accept-jumbo parameter is set to enable jumbo
frames for all Sun 10-Gigabit Ethernet devices. See the driver.conf(4)man page
for more information.
accept-jumbo=1;
In the following example, the accept-jumbo parameter is set to enable jumbo
frames is set for a single instance of the Sun 10-Gigabit Ethernet device.
In this example:
▼ parent= "/pci@8,600000"
▼ unit-address= "0"
name="pci8086,1048.108e.7036" parent="pci@8,600000" unit-address=
"0" accept-jumbo=1;
Note – If you omit the name=, parent=, and unit-address= definitions, the
settings become global to all Sun 10-Gigabit Ethernet instances.
3. Save the ixge.conffile.

Configuration Checking
The jumbo frame configuration checking occurs at Layer 2 or Layer 3, depending on
the configuration method.
Layer 2 Configuration Checking
You can view the MTU configuration of a ixgeinstance at any time using the kstat
command. The kstatmac_mtu variable represents the complete size of the
Ethernet frame, which includes the Ethernet header, maximum payload, and crc.
This value is consistent with the definition of MTU presented by switch vendors.
Use the following command to get the information:.
# kstat ixge:0 | grep mac_mtu
mac_mtu
8192
Layer 3 Configuration Checking
You can check the Layer 3 configuration by invoking the ifconfigcommand on a
preconfigured interface as shown in the previous examples:.
# ifconfig ixge138000
ixge138000: flags=

CHAPTER

Configuring VLANs
This chapter explains Virtual Local Area Networks (VLANs) in detail and provides
configuration instructions and examples. It contains the following sections:
▼ “Overview of VLANs” on page 37
▼ “Configuring VLANs” on page 39
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 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.
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.

FIGURE 4-1 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.
38

▼ 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 10-Gigabit 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 switch’s Gigabit Ethernet ports, which is configured for
VLANs 1, 2, and 3. Both the adapter and the connected switch 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 following list describes the
components of this network:
▼ 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 10-Gigabit 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 end-
stations, 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 (ixge0, ixge1,
ixge2and 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

39
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). FIGURE 4-2
shows the Ethernet Tag Header format.

FIGURE 4-2 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.
▼ To Configure Static VLANs
1. Create one hostname6.ixgenumber file for each VLAN that will be configured for
each adapter on the server.
Use the following naming format, which includes both the VID and the physical
point of attachment (PPA):
VLAN logical PPA = 1000 * VID + Device PPA
ixge123000 = 1000*123 + ixge
This format limits the maximum number of PPAs (instances) you can configure to
1000 in the /etc/path_to_instfile.
For example, on a server with the Sun 10-Gigabit Ethernet adapter having an
instance of 0, belonging to a member of two VLANs, with VID 123 and 224, you
would use ixge123000and ixge224000, respectively, as the two VLAN PPAs.
40

2. Use the ifconfig(1M)to configure a VLAN virtual device, for example:
# ifconfig ixge123000 plumb up
# ifconfig ixge4000 plumb up
The output of ifconfig -aon a system having VLAN devices ixge123000and
ixge224000:
# ifconfig -a

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.

TABLE D-1 Tunable ixgeDriver Parameters for Linux Operating Systems
Keyword
Description
FlowControl
Valid Range: 0-3 (0=none, 1=Rx only, 2=Tx only, 3=Rx&Tx)
Default: Read from the EEPROM
If EEPROM is not detected, default is 3.
This parameter controls the automatic generation (Tx) and response
(Rx) to Ethernet PAUSE frames.
RxDescriptiors Valid Range: 64-4096
Default Value: 1024
This value is the number of receive descriptors allocated by the driver.
Increasing this value allows the driver to buffer more incoming packets.
Each descriptor is 16 bytes. A receive buffer is also allocated for each
descriptor and can be either 2048, 4056, 8192, or 16384 bytes, depending
on the MTU setting. When the MTU size is 1500 or less, the receive
buffer size is 2048 bytes. When the MTU is greater than 1500 the receive
buffer size will be either 4056, 8192, or 16384 bytes. The maximum MTU
size is 16114.
RxIntDelay
Valid Range: 0-65535 (0=off)
Default Value: 72
This value delays the generation of receive interrupts in units of 0.8192
microseconds. Receive interrupt reduction can improve CPU efficiency
if properly tuned for specific network traffic. Increasing this value adds
extra latency to frame reception and can end up decreasing the
throughput of TCP traffic. If the system is reporting dropped receives,
this value may be set too high, causing the driver to run out of available
receive descriptors.
TxDescriptors
XsumRX
Valid Range: 64-4096
Default Value: 256
This value is the number of transmit descriptors allocated by the driver.
Increasing this value allows the driver to queue more transmits. Each
descriptor is 16 bytes.
Valid Range: 0-1
Default Value: 1
A value of 1 indicates that the driver should enable IP checksum offload
for received packets (both UDP and TCP) to the adapter hardware.
