Configuring the IPoIB Network Interface
The following instructions show you how to manually configure your OpenFabrics
IPoIB network interface. This example assumes that you are using
sh or bash as
your shell, all required InfiniPath and OpenFabrics RPMs are installed, and your
startup scripts have been run (either manually or at system boot).
For this example, the IPoIB network is 10.1.17.0 (one of the networks reserved for
private use, and thus not routable on the Internet), with a /8 host portion, and
therefore requires that the netmask be specified.
This example assumes that no hosts files exist, the host being configured has the
IP address 10.1.17.3, and DHCP is not used.
1. Type the following commands (as root):
# ifconfig ib0 10.1.17.3 netmask 0xffffff00
2. To verify the configuration, type:
# ifconfig ib0
The output from this command will be similar to this:
ib0 Link encap:InfiniBand HWaddr
00:00:00:02:FE:80:00:00:00:00:00:00:00:00:00:00:00:00:00:00

TX packets:0 errors:0 dropped:0 overruns:0 carrier:0

RX bytes:0 (0.0 b) TX bytes:0 (0.0 b)
3. Type:
# ping -c 2 -b 10.1.17.255
The output of the ping command will be similar to the following, with a line
for each host already configured and connected:
WARNING: pinging broadcast address
PING 10.1.17.255 (10.1.17.255) 517(84) bytes of data.
174 bytes from 10.1.17.3: icmp_seq=0 ttl=174 time=0.022 ms

64 bytes from 10.1.17.7: icmp_seq=0 ttl=64 time=0.073 ms (DUP!)
The IPoIB network interface is now configured.
NOTE:
Instructions are only for this static IP address case. Configuration methods
for using DHCP will be supplied in a later release.
