HP ProCurve 3500-24 Openflow Connectivity

[philipisaia]

Hi everyone,

I am trying to configure HP ProCurve 3500-24 (J9470A) to work as an openflow switch with an openflow controller (POX).

What I did is that I created a VLan that has 1 port and is used for the controller (HP recommends the controller to be in a separate VLan) and also I have create a VLan than has 4 ports and that will be used by the hosts as the openflow switch.  Then I have created a controller with IP address and ID.

I have used several configurations but none of them was able to connect to the POX controller.  One forum that I visited says that there is a problem with openflow in the new K.15.10.0003 firmware, which is the one I use.

Is that a problem of the firmware? Or is it a problem with my configuration? 

just to mention that once I connect the four hosts, I can ping between hosts, so it seems that it works perfectly as a normal switch, but not as an openflow.

Here is my pcc configuration file.  Is there anything that you can suggest?

Hi,

I won't admit to knowing much about OpenFlow, so please excuse me if this is a silly question, but wouldn't the OpenFlow controller's IP address need to be different to the VLAN 10 gateway IP address?

Does the POX controller just need a stipulated VLAN to communicate with the switch(s)? i.e. VLAN10 is your controller VLAN, but the IP of the controller and the switches that are members of it need to all be on different IPs?

Hi philipisaia,

How is your problem? Now i face the same problem as you.

If you can solve it, can you share us?

Thanks
