LAN over USB Linux Driver Installation
Use this information to install the LAN over USB driver for Linux.
Current versions of Linux, such as RHEL5 Update 2 and SLES10 Service Pack 2,
support the LAN over USB interface by default. This interface is detected and
displayed during the installation of these operating systems. When you configure
the device, use a static IP address of 169.254.95.130 with a subnet mask of
255.255.0.0.
Note: Older Linux distributions might not detect the LAN over USB interface, and
might require manual configuration. For information about configuring LAN over
USB on specific Linux distributions, see the IBM white paper Transitioning to UEFI
and IMM on the IBM web site (see "Related documentation" on page 7 for
information on how to find publications for your blade server).
The IMM LAN over USB interface requires that the usbnet and cdc_ether drivers
be loaded. If the drivers have not been installed, use modprobe to install them.
When these drivers are loaded, the IMM USB network interface shows up as a
network device in the operating system. To discover the name that the operating
system has assigned to the IMM USB network interface, type:
dmesg | grep -i cdc ether
The interface is configured with ifconfig to have an IP address in the range
169.254.xxx.xxx. For example:
ifconfig IMM_device_name 169.254.1.102 netmask 255.255.0.0
This interface is configured to come up with an IP address in the 169.254.xxx.xxx
range each time that the operating system is booted.
