Hi, Nicholas
I launch ryu-manager ryu/app/simple_switch_13.py ryu/app/ofctl_rest.py in
another new terminal
It is not a problem. It's all right if you can run your application in
somewhere.
However...
OVS' version: 2.0.2.
You use an older version of OVS, almost 3 years ago.
And I succeeded to reproduce your situation with OVS 2.0.2.
(I think this version does not comply completely with OpenFlow1.3.)
Please use the latest version of OVS.
It should fix your problem.
Thanks,
Fujimoto

Hi, Fujimoto.
First of all, I don't go like you for 3. run application. I launch ryu-manager
ryu/app/simple_switch_13.py ryu/app/ofctl_rest.py in another new terminal, not
in C0 (because error: Traceback (most recent call last):

My Ryu's version: 4.15, OVS' version: 2.0.2.

Oggetto: Re: [Ryu-devel] Bug REST Ryu Delete all flow entry
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.
