unsupported version 0x01. If possible, set the switch to use one of the versions [4]

Hello, just wanted to let you know that this looks extremely promising for issuing bandwidth control on physical networks as well. For right now, I am just trying to make it through your README but am encountering an OpenFlow protocol problem. When I try

ryu-manager Switch.py

or

ryu-manager Rest.py

I encounter the error that the title of this issue shows. Do you have any idea how I may resolve this issue? I am a little perplexed because I thought Ryu adapted to any OpenFlow version and when I run these files without opening mininet first I still get this error. Any insights on how to get past this?

Hello,
I think the problem is that you are using a switch which doesn't support OpenFlow 1.3. The error log says that you are using OpenFlow 1.0.
In the example topology I use CPqD Switch, which support both: OpenFlow 1.3 and meter tables.
I recommend you checking the switch that you are using to run the script.
Regards.

Isn't the switch in theory whatever the mininet topology [topo.py] says it
is? [Isn't this tutorial entirely virtual networking?] So if I am using
this topology then why am I getting the error?

Did you use the CPdQ switch instead of mininet's virtual OpenFlow switches
because you were unable to get them to perform the tasks you wanted?

I used cpqd because it has the meter table implemented, which I use to control the bw.
If you are using the topo.py to create the topology, I don't know why this error happen, maybe the UserSwitch implemented in mininet is not cpqd anymore (this project is about 1 year ago), so check that. (Ovs doesn't support meter tables)
Regards.
