Sorry if this is too crude, but the simplest answer is to disable one network at a time, on all the servers in the cluster. This can be done in software, with a usually minor edit of the OS configuration files (which ones depends on the particular linux you’re running) then restarting the network services. Rebooting is not usually required.
I’m assuming that, since you’re running benchmarks, you have dedicated hardware that you can tweak as desired.

I have a cluster in which all nodes are connected through both Ethernet and Infiniband. But I am lost as to how to configure Storm to perform communication over Infiniband in one case and Ethernet in another. From what I understand, Storm does not allow us to specify the IPs of slave (supervisor) nodes, or else we could have just entered the address if Inifininand interconnect there.
