Note – In RHEL5.0 and later releases, the driver is packaged in the kmod driver binary package format. This packaging allows forward and backward driver binary compatibility within the same flavors of RHEL5 releases. Driver packages nxge version 2.0.0 and later are not compatible with the earlier nxge-1.x-x releases. To upgrade from 1.x-x to 2.x.x rpm package, it is necessary to remove nxge-1.xx package before installing the 2.x.x package. The RHEL5 nxge 2.x.
7. Use the ethtool command to check the parameter configurations that apply to the nxge driver. (For 10G) # ethtool -i eth4 driver: nxge version: 2.0.1 firmware-version: 2XGF PXE1.47 FCode 3.9 07/04/24 bus-info: 0000:84:00.0 (Equivalent for 1G) # ethtool -i eth4 driver: nxge version: 2.0.1 firmware-version: QGC PXE1.47 FCode 3.9 07/04/24 bus-info: 0000:02:00.2 ▼ To Remove the Driver From a Linux Platform ● To remove the driver packages from a Linux Platform use the rpm -e command: # rpm -e nxge-1.
CHAPTER 3 Installing the Adapter This chapter describes how to install the Sun x8 Express Dual 10 Gigabit Ethernet Fiber XFP Low Profile Adapter in your system and verify that it has been installed correctly.
Caution – Sun x8 Express Dual 10 Gigabit Ethernet Fiber XFP Low Profile Adapter mechanical fit limitations: Do not install the Sun x8 Express Dual 10 Gigabit Ethernet Fiber XFP Low Profile Adapter in slot-2 of a Sun Fire T2000 system. The SATA cables from the adjacent card slot prevent the proper installation of an Sun x8 Express Dual 10 Gigabit Ethernet Fiber XFP Low Profile Adapter in this slot. (Note that this issue does not exist for Sun Fire T2000 that is RoHS compliant.
Note – These illustrations show the Sun x8 Express Dual 10 Gigabit Ethernet Fiber XFP Low Profile Adapter being installed into a Sun Fire T2000, which requires a standard height bracket for the low profile adapter. 6. Open the retaining clip at the edge of the PCI-E opening. 7. Holding the adapter by the edges, align the adapter edge connector with the PCI-E slot. Slide the adapter face plate into the small slot at the end of the PCIE opening. 8.
9. Secure the retaining clip Caution – Do not use excessive force when installing the adapter into the PCI-E 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. 10. Detach the wrist strap and close the system unit.
11. Install the optical transceivers. Note – Illustrations for installing the adapter and installing the optical transceiver show different systems. This difference in systems provides the maximum clarity for installing the optical transceiver and shows the most complicated adapter installation. Installing an Optical Transceiver The Sun x8 Express Dual 10 Gigabit Ethernet Fiber XFP Low Profile Adapter requires an optical transceiver in each port to create and Ethernet connection.
▼ To Install an Optical Transceiver 1. Pull the white locking handle into the full horizontal position. You will feel the handle click into position when it is fully opened. Note – If you are installing an optical transceiver in a Sun Fire T1000, ensure that the label and the edge connector is visible to you. 2. Holding the optical transceiver by the edges, align the transceiver with the slot in the Sun x8 Express Dual 10 Gigabit Ethernet Fiber XFP Low Profile Adapter and slide it into the opening. 3.
4. Push the handle closed to lock the optical transceiver in place. 5. Repeat Step 1 through Step 4 to install the second optical transceiver 6. Detach the wrist strap. Caution – If you pull the locking handle down when the optical transceiver is installed, remove the optical transceiver entirely and reinstall it. The handle operates an internal lock. Pulling the handle down can disconnect the optical transceiver, even though it might appear to be connected.
7. Connect the Ethernet cables. Verifying the Hardware Installation After you have installed the Sun 10-Gigabit 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 dynamic reconfiguration (DR). Verification is not supported if your system is running Solaris x86 software. ▼ To Verify the Hardware Installation 1.
3. View the device that you installed. Using the previous example, type: ok cd /pci@7c0/pci@0/pci@8/network@0,1 4. Use the .properties command to display a list of device properties. The .properties command displays the specific information about the device. If you are using the Sun x8 Express Dual 10 Gigabit Ethernet Fiber XFP Low Profile Adapter, your output will be similar to the following: ok .
5. Type the following when you finish looking at the .properties values: ok device-end Rebooting the System After verifying the adapter installation, use the boot -r command to perform a reconfiguration boot on your system.
CHAPTER 4 Network Configuration This chapter describes how to edit the network host files after the adapter has been installed on your system.
1. At the command line, use the grep command to search the /etc/path_to_inst file for nxge interfaces. # grep nxge /etc/path_to_inst # "/pci@7c0/pci@0/pci@9/network@0" 0 "nxge" # "/pci@7c0/pci@0/pci@9/network@0,1" 1 "nxge" # In this example, the device instance is from a Sun x8 Express Dual 10 Gigabit Ethernet Fiber XFP Low Profile Adapter installed in slot 1. Be sure to write down your device path and instance, which in the example is "/pci@7c0/pci@0/pci@9/network@0" 0.
■ The host name must be different from any other host name of any other interface, for example: /etc/hostname.nxge0 and /etc/hostname.nxge1 cannot share the same host name. The following example shows the /etc/hostname.nxgenumber file required for a system called zardoz that has a Sun x4 PCI-Express Gigabit Ethernet driver (zardoz-11). # cat /etc/hostname.nxge0 zardoz # cat /etc/hostname.nxge1 zardoz-11 3. Create an appropriate entry in the /etc/hosts file for each active nxge interface.
▼ To Set Up a 10-Gigabit 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. Download the software for Sun x8 Express Dual 10 Gigabit Ethernet Fiber XFP Low Profile Adapter onto the server’s drive. 3.
Installing the Solaris Operating System Over a 10-Gigabit 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.
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_10/Tools/Boot install=server-name:/netinstall boottype=:in rootopts=:rsize=32768 In this example, the root directory for the Solaris 10 client is /netinstall.
5. Shut down and halt the client system. Use the shutdown command to go to the OpenBoot (ok) prompt. # shutdown -i0 -g0 -y . . . (shutdown command messages omitted) . . . ok 6. At the ok prompt, use the show-nets command to find the device path of the 10-Gigabit Ethernet device. The show-nets command lists the system devices. You should see the full paths and names of the network devices, similar to the example below.
■ If the software is installed, the previous command will return the package name you typed in. In that case, skip to Step 10. ■ If the software is not installed, install the software from the download center. See Chapter 2 for instructions on installing the required software packages. 10. Confirm that the network host files have been configured correctly during the Solaris installation.
4. Plug the Ethernet cable to the adapter port. 5. Power on the system. 6. Press the F2 key or the Control/E keys to go to the BIOS. 7. Check and make sure that the boot order of Hard Drive is higher than network devices. 8. Refer the boot-device-order image. The reconfiguration boot attaches the driver to the adapter. You can now configure the driver parameters for your Sun x8 Express Dual 10 Gigabit Ethernet Fiber XFP Low Profile Adapter. 9.
10. Press the F12 key to install the OS from the network. If the cable is connected to the right port, you should see the MAC address that you assigned to your PXE server displayed by BIOS. image : pxe-mac-addr PXE-E61: Media test failure, check cable PXE-MOF: Exiting Intel Boot Agent.

CHAPTER 5 Configuring the nxge Device Driver Parameters The nxge device driver controls the Sun x8 Express Dual 10 Gigabit Ethernet interfaces. You can manually set the nxge driver parameters to customize each device in your system. This chapter lists the available device driver parameters and describes how you can set these parameters.
processing. The Sun 10-Gigabit Ethernet Adapter utilizes Sun’s own innovative MAC Controller to map the 10-Gigabit XAUI interface onto the PCI Express form factor. It supports 10 Gb/sec bandwidth using eight transmit and eight receive lanes. Setting nxge Driver Parameters on a Solaris Platform You can set the nxge device driver parameters in two ways: ■ Using the ndd utility ■ Using the nxge.conf file If you use the ndd utility, the parameters are valid only until you reboot the system.
▼ To Specify Device Instances for the ndd Utility Before you use the ndd utility to get or set a parameter for a nxge 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.
After you enter the parameter name, the ndd utility prompts you for the parameter value. 2. To list all the parameters supported by the nxge driver, type ?.
▼ To Set Driver Parameters Using an nxge.conf File 1. Obtain the hardware path names for the nxge devices in the device tree. a. Check the /etc/driver_aliases file to identify the name associated with a particular device: # grep nxge /etc/driver_aliases nxge "pciex108e,abcd" b. Locate the path names and the associated instance numbers in the /etc/path_to_inst file.
# 10 gigabit related parameters ( i.e adv_10gfdx_cap) # apply only to 10gigabit ports. # Half duplex is not supported on any NIU card. # # adv-autoneg-cap # Advertise auto-negotiation capability. # default is 1 # adv-autoneg-cap = 1; # # adv_10gfdx_cap # Advertise 10gbps Full duplex capability. # default is 1 # adv_10gfdx_cap = 1; # # adv_1000fdx_cap # Advertise 1gbps Full duplex capability. # default is 1 # adv_1000fdx_cap = 1; # # adv_100fdx_cap # Advertise 100mbps Full duplex capability.
# # #------- Receive DMA Configuration ---------------------------# # rxdma-intr-time # Interrupts after this number of NIU hardware ticks have # elapsed since the last packet was received. # A value of zero means no time blanking (Default = 8). # # rxdma-intr-pkts # Interrupt after this number of packets have arrived since # the last packet was serviced. A value of zero indicates # no packet blanking (Default = 20). # # Default Interrupt Blanking parameters.
b. The following parameters operate on a per port basis and can be set using the /platform/sun4u/kernel/drv/nxge.conf file. # # # # # # # # # # # # # # # # # # # = # # = # # = # # = # ------- How to set parameters for a particular interface -------The example below shows how to locate the device path and set a parameter for a particular nxge interface.
d. The following example shows ports on two different cards being set. Only one node needs to be specified. name = "pciex108e,abcd" parent = "/pci@780/pci@0/pci@8/" unit-address = "0" class-opt-ipv4-tcp = 0x100; name = "pciex108e,abcd" parent = "/pci@7c0/pci@0/pci@9/" unit-address = "0" class-opt-ipv4-tcp = 0x40; 3. Save the nxge.conf file.
3. Add the following to a startup script, or use ndd before plumbing the interface: # ndd -set /dev/ip ip_soft_rings_cnt 8 Utilizing more soft-rings provided by the Solaris TCP/IP stack significantly improves bulk throughput for Rx. The default number of soft-rings is 2, but changing it to 8 improves performance. (You can increase the number to 16 in UltraSparc-T1 based systems). ▼ To Improve Performance on an AMD CPU Based Sun Platform 1.
▼ To Obtain Higher Throughput Using the Generic Tunables for the Solaris TCP/IP Stack ● To obtain higher throughput, add the following to a startup script: ndd ndd ndd ndd ndd ndd -set -set -set -set -set -set /dev/tcp /dev/tcp /dev/tcp /dev/tcp /dev/tcp /dev/tcp tcp_conn_req_max_q 8192 tcp_conn_req_max_q0 8192 tcp_max_buf 4194304 tcp_cwnd_max 2097152 tcp_recv_hiwat 400000 tcp_xmit_hiwat 400000 Chapter 5 Configuring the nxge Device Driver Parameters 43

CHAPTER 7 Configuring Link Aggregation This chapter describes how to configure link aggregation. It contains the following sections: ■ “Overview of Link Aggregation” on page 57 ■ “Configuring Link Aggregation in a Linux Environment” on page 60 Overview of Link Aggregation Link Aggregation allows one or more network links to be aggregated together to form a link aggregation group. This link aggregation group appears to MAC clients as a regular link. Link aggregation is defined by IEEE 802.
Configuring Link Aggregation in a Solaris Environment This section explains how to configure link aggregation in a Solaris environment. ▼ To Configure Link Aggregation in a Solaris Environment 1. Aggregate nxge0 and nxge1 to form an aggregation and a random number 33 as key. a. Unplumb the interfaces to be aggregated: # ifconfig down unplumb nxge0 # ifconfig down unplumb nxge1 b.
2. Plumb up the interface aggrkey, which is aggr33 is this case: # ifconfig aggr33 plumb # ifconfig aggr33 aggr33: flags=1000842 mtu 1500 index 8 inet 0.0.0.0 netmask 0 ether 0:3:ba:d8:9d:e8 # ifconfig aggr33 192.168.1.1/24 broadcast + up # ifconfig aggr33 aggr33: flags=1000843 mtu 1500 index 8 inet 192.168.1.1 netmask ffffff00 broadcast 192.168.1.255 ether 0:3:ba:d8:9d:e8 3.
Configuring Link Aggregation in a Linux Environment This section explains how to configure link aggregation in a Linux environment. ▼ To Configure Bonding for Multiple nxge Interfaces 1. Modify the /etc/modprobe.conf file for 2.6 kernels file by adding these lines: alias bond0 bonding options bonding max_bonds=2 mode=4 miimon=1000 where: ■ bond0 is the bonding device. ■ max_bonds is the number of bond interfaces to be created. ■ mode specifies the bonding policies.
CHAPTER 8 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 61 ■ “Configuring VLANs in a Solaris Environment” on page 63 ■ “Configuring VLANs in a Linux Environment” on page 65 With multiple VLANs on an adapter, a server with a single adapter can have a logical presence on multiple IP subnets.
FIGURE 8-1 shows an example network that uses VLANs. FIGURE 8-1 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.
Gigabit Ethernet ports, which is configured for VLANs 1, 2, and 3. Both the adapter and the connected switch port have tagging turned on. The tagging VLAN capabilities of both devices enable the sever to communicate on all three IP subnets in this network, yet continue to maintain broadcast separation among the three subnets. 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.
FIGURE 8-2 Ethernet Tag Header Format Octet 1 TPID (0x8100 3 bits 1 bit User_priority CFI 12 bytes 2 3 4 VID By default, a single VLAN is configured for every port. This groups all ports into the same broadcast domain, just as if there were no VLANs at all, VLAN tagging for the switch port is 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 hostname.
2. Use the ifconfig(1M) to configure a VLAN virtual device, for example: # ifconfig nxge123000 plumb up # ifconfig nxge224000 plumb up The output of ifconfig -a on a system having VLAN devices nxge123000 and nxge224000: # ifconfig -a lo0: flags=1000849 mtu 8232 index 1 inet 127.0.0.1 netmask ff000000 hme0: flags=1000843 mtu 1500 index 2 inet 129.144.131.91 netmask ffffff00 broadcast 129.144.131.
2. Plumb Oracle’s Sun x8 Express Dual 10 Gigabit Ethernet Fiber XFP Low Profile Adapter interface: # ifconfig eth2 xxx.xxx.xx.xxx up where xxx.xxx.xx.xxx = the IP address of the interface. 3. Insert the VLAN module: # /sbin/modprobe 8021q 4. Add the VLAN instance (VID): # /sbin/vconfig add eth2 5 5. Configure the nxge VLAN (eth2 in this example): # ifconfig eth2.5 xxx.xxx.xx.xxx up where xxx.xxx.xx.xxx = the IP address of the interface.
