Hi,
I recently met the following problem. I tried to communicate NOX with Pronto switches which are based on OVS. And I tested IP packets flow. However when IP packets arrive controller, I find that these packets have VLAN tags. Therefore the NOX will treat them as VLAN packets and set the type= 0x8100. However this flow entry will not work on next packets at all. I used attributes = extract_flow(packet) to get all the attributes which include type= 0x8100. I need change the type to 0x8000 (i.e. IP). Is it possible to do that?Which syntax should I run? Thanks very much. Weiyang
