Hi, corey Sorry, OVS 2.8.0 has a problem so it may be difficult to run it...
OVS 2.8.0 can not work with passive controller connection, it will crash. The fix has been merged to master, but it is not released yet: https://github.com/openvswitch/ovs/commit/1ea2184501d43352ec40764f5eaa3cbd07e3fee3 I think it is better to try with OVS 2.7.2. It is stable . Could you try with it? Thanks, Fujimoto On 2017年09月27日 20:00, corey ross wrote:

Please confirm the followings: * Using the latest version of Ryu(4.17) * (If you use OVS,) Using the latest version of OVS(2.8.0) If confirmed, would you send me the whole of your code?

What is the correct way to request for table features (during) handshake?
