Hi, ryu team:
When I run ryu simple_switch_13 on mininet emulator with a tree topo, I
can't get the flow table. the dedatil shows in below:
run mininet with tree topo:
sudo mn --controller remote --topo tree,depth=2 --switch
ovs,protocols=OpenFlow13 --mac
mininet> pingall
*** Ping: testing ping reachability
h1 -> h2 h3 h4
h2 -> h1 h3 h4
h3 -> h1 h2 h4
h4 -> h1 h2 h3
*** Results: 0% dropped (12/12 received)
mininet> dpctl dump-flows
*** s1 ------------------------------------------------------------------------
2014-11-02T06:27:42Z|00001|vconn|WARN|unix:/var/run/openvswitch/s1.mgmt:

ovs-ofctl: s1: failed to connect to socket (Broken pipe)
*** s2 ------------------------------------------------------------------------
2014-11-02T06:27:42Z|00001|vconn|WARN|unix:/var/run/openvswitch/s2.mgmt:

ovs-ofctl: s2: failed to connect to socket (Broken pipe)
*** s3 ------------------------------------------------------------------------
2014-11-02T06:27:42Z|00001|vconn|WARN|unix:/var/run/openvswitch/s3.mgmt:
version negotiation failed (we support version 0x01, peer supports version 0x04)
ovs-ofctl: s3: failed to connect to socket (Broken pipe)
I only get the "version negotiation failed" error message.
Any help is much appreciated.
Thanks!
