Hi Ali, I want to add flow entry to my switch for a slice running NOX controller, and FlowVisor is running too. Can you send me some examples of how to add flow? Both FlowVisor and NOX are running on the same host(I.e. same IP), but different port, and the host is running Ubuntu Server LTS 12.04, and my switch is NetGear GSM7328 with Indigo OF flash loaded.
