94 Implementing Cisco InfiniBand on IBM BladeCenter

This completes the IPoIB configuration process.

5.2.4 Verifying the IPoIB communication

To verify IPoIB functionality on Linux hosts:

1. Login in to the hosts and ensure that the IPoIB interfaces on the source and destination

nodes are up by using the ifconfig command specified in Example 5-6 on page 86.

2. Issue a ping command between a source node to a destination node to ensure successful

IPoIB communication as shown in Figure 5-12.

Figure 5-12 Verify IPoIB communication across the blades

To test a Windows host, use the same steps, except instead of using ifconfig to verify the

ib0/1 interfaces are present and configured, use the ipconfig command.
