IPoIB Network Interface Configuration
3-4 IB0054606-02 A
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 command (as a root user):
ifconfig ib0 10.1.17.3 netmask 0xffffff00
2. To verify the configuration, type:
ifconfig ib0
ifconfig ib1
The output from this command will be similar to:
ib0 Link encap:InfiniBand HWaddr
00:00:00:02:FE:80:00:00:00:00:00:00:00:00:00:00:00:00:00:

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

(DUP!)
64 bytes from 10.1.17.7: icmp_seq=0 ttl=64 time=0.073 ms
(DUP!)
The IPoIB network interface is now configured.
4. Restart (as a root user) by typing:
/etc/init.d/openibd restart
NOTE
Instructions are only for this static IP address case. Configuration methods
for using DHCP will be supplied in a later release.
