Hi, Nicholas
Umm.... That's strange. I couldn't reproduce your situation with my
environment.
I took the following step.
1. run mininet
$ sudo mn --topo single,2 --mac --switch ovsk --controller remote -x
2. set OpenFlow version to s1
s1> ovs-vsctl set Bridge s1 protocols=OpenFlow13
3. run application
c0> ryu-manager ryu/app/simple_switch_13.py ryu/app/ofctl_rest.py
4. send ping
mininet> h1 ping h2
5. get flow stats
c0> curl -X GET http://localhost:8080/stats/flow/1
(I got "OUTPUT:CONTROLLER", "OUTPUT:1", "OUTPUT:2")
6. clear flows
c0> curl -X DELETE http://localhost:8080/stats/flowentry/clear/1
7. send ping again
mininet> h1 ping h2
(the ping is not reachable at this time)
8. get flow stats
c0> curl -X GET http://localhost:8080/stats/flow/1
(I got no flows)
It may be that you use older version of Ryu or OVS, could you confirm it?
Please hit the following command for Ryu and OVS.
$ ryu-manager --version
ryu-manager 4.16
$ovs-ofctl -V
ovs-ofctl (Open vSwitch) 2.7.90
Thanks,
Fujimoto

Hi Fujimoto! I run ofctl and simple_switch_13.py. I would like to use
OpenFlow 1.3 but if it isn't possible...thanks!

Hi, Nicholas
I think you may use simple_switch_xx.py for OpenFlow < 1.3.
In OpenFlow < 1.3, the packet which is not matched to any flows will
be sent as Packet-In (OUTPUT:CONTROLLER).
It may be that the controller installs OUTPUT:1 and OUTPUT:2 in
Packet-In handler.
In any case, I would like to know what applications you ran, could
you let me know?
Thanks,
Fujimoto

Hi guys! In my web-app with REST call Ryu, I have found a possible
bug. When I launch url -X DELETE
http://localhost:8080/stats/flowentry/clear/1 to delete every flow
in switch 1, the OUTPUT:CONTROLLER (flow of controller Ryu) deleted
with OUTPUT:1 and OUTPUT:2. But if I launch h1 ping h2 in terminal,
if I launch http://localhost:8080/stats/switches
<http://localhost:8080/stats/switches/clear/1> I don't see
OUTPUT:CONTROLLER flow but only OUTPUT:1 and OUTPUT:2. Why?? Thanks,
Nicholas.
