Hi, I've just joined the list and found this in the archive. I don't know how to respond to an older thread, so I post it here:
Have you had any success yet? I'm also working with Ryu and HP switches and experienced similar behaviours. As far as I understand this, it's not an issue with Ryu but rather that the switch accepts the command because the syntax is correct but can't install the flow. HP switches have some limitations on what types of actions and matches the can install in certain tables. Per default flows in table 100 will be handled by hardware and flows in table 200 will be handled in software. So if you try to install a flow in a 'hardware table' and the switch can't process that flow in hardware it simply won't install the flow and also don't give an error message. I'm thinking of implementing 2 solutions: First I don't let users install flows the switch can't process. (This is tricky to implement because I don't yet fully grasp which flows HP supports) and secondly after a add-flow I get all flows and check if it has been installed. If not I throw a warning in the interface. Hope this helps a little. Cheers Marvin And props to the Ryu Team. I really like this controller!
