Hi,
I am new to RYU controller, so kindly pardon me if this is a basic
question.
I am using the Ryu controller and a switch to setup a basic ping experiment
where I want to verify that two laptops connected to the same openflow
switch are able to ping each other.
I have installed OpenFlow 1.3 on a Linksys WRT54G router. I have installed
RYU controller on my laptop. I connect my laptop to port 4 on the switch,
and another laptop to port 2 on the switch.
Then I start the controller, and load the ofctl_rest.py app.
When I connect the switch to the controller, I get a log line saying that
the switch has connected successfully. I am also able to verify that ping
from my laptop to another laptop (and vice-versa) works fine.
Now I want to look at the stats of the switch, so I do
curl "http://127.0.0.1:8080/stats/switches";
but this returns me an empty json response []. Since I have at least 1
switch connected to the controller, I expect at least some output.
I also look at the controller and it has the log line
127.0.0.1 - - [15/Sep/2013 17:41:25] "GET /stats/switches HTTP/1.1" 200 109
0.004117
so I know that my request was correct.
I am not able to understand what am I doing wrong, so kindly help.
If it helps in answering, I am pasting the entire controller output below -

And here is the command output -

Thanks,
