Installing the LAN over USB Linux device driver
Versions of Linux since RHEL5 Update 3 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.
See Table 3 on page 48 for information about the IP addresses.
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 http://www.ibm.com/support/entry/
portal/docdisplay?lndocid=MIGR-5083207.
The IMM2 LAN over USB interface requires that the usbnet and cdc_ether device
drivers be loaded. If the drivers have not been installed, use modprobe to install
them. When these drivers are installed, the IMM2 USB network interface is shown
as a network device in the operating system. To discover the name that the
operating system has assigned to the IMM2 USB network interface, type
dmesg | grep -i cdc ether
Potential conflicts with the LAN over USB interface
In some situations, the LAN over USB interface can conflict with certain network
configurations, applications, or both. For example, Open MPI attempts to use all
the available network interfaces on a server or compute node. Open MPI detects
the IMM2 LAN over USB interface and attempts to use it to communicate with
