Re: [Ryu-devel] Starting up InBand Ryu controller
Hi Soliman,
I cannot answer for the contents of the Blog post you mentioned, because it is
not the official document of Ryu project and this issue seems be on Mininet
script side.

I tried this script on my machine, but OVS switches does not seem to try to
connect to Ryu's host.
How about getting contact to the creator of this script?
Thanks,
Iwase

On the one hand, I have no problem when I use these instructions on
http://tocai.dia.uniroma3.it/compunet-wiki/index.php/In-band_control_with_Open_vSwitch
(sudo mn --topo linear,5 --switch ovsk,inband=True
--controller=remote,ip=10.0.0.3)
when I check the disable-in-band="true" by
sudo ovs-vsctl --columns=other_config list bridge | grep "disable-in-band"
I get nothing as it is expected, and I can run the topology well. (pingall)
On the other hand, when I use the other topologies in (for example)
https://techandtrains.com/2013/10/05/in-band-controller-with-mininet-part-2/
or
https://github.com/hmd1st/mn_test/blob/master/inband_delay_link.py
I check the disable-in-band="true"
I get --> other_config: {datapath-id="0001",
disable-in-band="true"}
and I can't do ping betwwen all hosts.
my ovs is 2.0.2 which support Of 1.0 as default so I uses simple_switch.py as
a controller
And as I told you, I upgraded my ovs and tried to use the suitable controller(
simple_switch_13.py ), but nothing happens.
I know my problem might be simple, but I have no idea why I cannot start up the
controller well.
Thanks in advance.

You are using the OpenFlow version 1.3, right?
"ryu/app/simple_switch.py" supposes the OpenFlow version 1.0, then you should use
"ryu/app/simple_switch_13.py" instead.
To confirm which version a Ryu application supports, please check "OFP_VERSIONS"
attribute on each application class.
