4.4.3.2 Static IPoIB Configuration

If you wish to use an IPoIB configuration that is not based on DHCP, you need to supply the

installation script with a configuration file (using the ‘-n’ option) containing the full IP configu-

ration. The IPoIB configuration file can specify either or both of the following data for an IPoIB

interface:

• A static IPoIB configuration

• An IPoIB configuration based on an Ethernet configuration

See your Linux distribution documentation for additional information about configuring IP

addresses.

The following code lines are an excerpt from a sample IPoIB configuration file:

# Static settings; all values provided by this file

IPADDR_ib0=11.4.3.175

NETMASK_ib0=255.255.0.0

NETWORK_ib0=11.4.0.0

BROADCAST_ib0=11.4.255.255

ONBOOT_ib0=1

# Based on eth0; each '*' will be replaced with a corresponding octet

# from eth0.

LAN_INTERFACE_ib0=eth0

IPADDR_ib0=11.4.'*'.'*'

NETMASK_ib0=255.255.0.0

NETWORK_ib0=11.4.0.0

BROADCAST_ib0=11.4.255.255

ONBOOT_ib0=1

# Based on the first eth<n> interface that is found (for n=0,1,...);

# each '*' will be replaced with a corresponding octet from eth<n>.

LAN_INTERFACE_ib0=

IPADDR_ib0=11.4.'*'.'*'

NETMASK_ib0=255.255.0.0

NETWORK_ib0=11.4.0.0

BROADCAST_ib0=11.4.255.255

ONBOOT_ib0=1

4.4.3.3 Manually Configuring IPoIB

This manual configuration persists only until the next reboot or driver restart.

To manually configure IPoIB for the default IB partition (VLAN), perform the following steps:

Step 1. To configure the interface, enter the ifconfig command with the following items:

• The appropriate IB interface (ib0, ib1, etc.)

• The IP address that you want to assign to the interface

• The netmask keyword
