[nox-dev] Matching flows on port numbers
Hi, I'm trying to install a flow that matches on IP as well as port numbers. I'm using the flow provided by calling extract_flow() on a packet as the argument to install_datapath_flow() but if I use 'dpctl dump-flows' on a switch the flow displayed does not have entries for tp_dst or tp_src. Is there something else I need to be doing in order to get matching on port numbers?

Re: [nox-dev] Multiple Nox with spanning_tree Running the same in the Machine
It looks like either the socket was left open from an ungraceful shutdown last time you ran NOX, or another application happens to be using the port that jsonmessenger is trying to use. If I recall, that would be port 2703. If you run lsof -i | grep 2703 you should be able to see which application is using that port. If it is a zombie NOX (or some other program you don't care about) you can kill it and try rerunning. Alternatively (if a program you care about is using 2703), you can try to make jsonmessenger use another different port. I think the command for that would be jsonmessenger=tcpport=portnumber On Wed, Sep 28, 2011 at 1:33 PM, Rafael Lopes rafaell...@gmail.com wrote: When i try to run two nox with the spanning_tree i get this error below.

Re: [nox-dev] Multiple Nox with spanning_tree Running the same in the Machine
I think in this case, the other program is another instance of NOX being run simultaneously. :) So the last suggestion applies. The commandline to start the second instance should be something like: ./nox_core -v -i ptcp:6635 jsonmessenger=tcpport=2704 spanning_tree routing -- Murphy On Sep 28, 2011, at 2:08 PM, Kyriakos Zarifis wrote: It looks like either the socket was left open from an ungraceful shutdown last time you ran NOX, or another application happens to be using the port that jsonmessenger is trying to use.

Re: [nox-dev] Matching flows on port numbers
I'd suggest that the first thing you do is examine the traffic from the controller to the switch. Wireshark with the OpenFlow dissector is the easiest way to do this. Take a look at the flow_mod on the wire and see if it looks like you think it should (whether tp_src and tp_dst are set right, etc.). -- Murphy On Sep 28, 2011, at 8:13 AM, Shrutarshi Basu wrote: Hi, I'm trying to install a flow that matches on IP as well as port numbers.
