Ensure your flow includes the following two Stanzas:

<match>
 <ethernet-match>
    <ethernet-type>
      <type>2048</type>
    </ethernet-type>
 </ethernet-match>

and

 <ip-match>
  <ip-protocol>6</ip-protocol>
 </ip-match>
</match>

using ip-protocol 6 will make it match on TCP, it's not for the ip version, which I can see how you might think ipv6. I think it should still be ok without, but if you want to limit to just TCP that's how: https://en.wikipedia.org/wiki/List_of_IP_protocol_numbers

Many thanks runamuck. BTW, I was reading your previous posts and answers for such question. :)

So I understand that Ethetype should be written to indicate which protocol is encapsulated in the payload of an Ethernet Frame. So the number indicates 2048 indicates that protocol used is IP v4. But I got confused what does it mean by <ip-protocol>6</ip-protocol>?

Could I find the documentation for the details of these XML tags?

Thanks again

As Jamo wrote, proto 6 means TCP. In terms of documentation, it's pretty sparse. What I like to do is use ovs-vsctl to create flows and then reverse-engineer in ODL to get the XML.
