Hi Ben, Thank you for your analysis.
>From output of "ovs-ofctl ofp-parse-pcap", I want to understand that below is parsing for Vendor message sent from controller. 192.168.6.8.6633 > 192.168.6.2.37637: NXT_SET_FLOW_FORMAT (xid=0x7): format=nxm It seems that vendor message is setting flow format.It might be setting flow format of flow mod sent as 6th packet. Can you please help me in telling ways to get vendor reply from switch? What I should send from controller to get vendor reply in response from Switch?
