Sun Microsystems 10GBE XFP manual # modprobe nxge

Page 28

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-xreleases. To upgrade from 1.x-x to 2.x.x rpm package, it is necessary to remove nxge-1.x- x package before installing the 2.x.x package.

The RHEL5 nxge 2.x.x kmod package contains two separate packages: One for the driver and another one for applications like nxge_config. You must install both of the following packages:

kmod-nxge-rhel-2.0-1.x86_64.rpm	(driver binary package)
nxge-apps-rhel-2.0-1.x86_64.rpm	(application package)

To install the complete package, enter the following:

#rpm -ivh nxge-apps-rhel-2.0-1.x86_64.rpm kmod-nxge-rhel-2.0-1.x86_64.rpm

To ensure that the driver is loaded after the rpm installation, enter the following:

#modprobe nxge

5.Verify the new network interface instances corresponding to the Sun x8 Express Dual 10 Gigabit Ethernet Fiber XFP Low Profile Adapter:

# ifconfig -a grep eth
eth0	Link encap:Ethernet	HWaddr 00:14:4F:20:F1:DC
eth1	Link encap:Ethernet	HWaddr 00:14:4F:20:F1:DD
eth2	Link encap:Ethernet	HWaddr 00:14:4F:20:F1:DE
eth3	Link encap:Ethernet	HWaddr 00:14:4F:20:F1:DF
eth4	Link encap:Ethernet	HWaddr 00:14:4F:6C:78:E8
eth5	Link encap:Ethernet	HWaddr 00:14:4F:6C:78:E9

The Sun x8 Express Dual 10 Gigabit Ethernet Fiber XFP Low Profile Adapter instances, eth4 and eth5, are shown in bold italics.

6.Add the nxge interfaces to the /etc/modules.conf file to automatically load the driver after system reboot:

alias eth4 nxge alias eth5 nxge
