I was trying to see a demo in the learning switch application that is given in below uRL.
I followed the steps given in above URL, compilation of both learning switch and the controller codes are successful. but when i launch the mininet as per the document, i am not able to ping from the hosts, also i am continuously seeing the message (above screen shot). is it normal? when i switch off the mininet the message stops updating in the controller console.
Any idea friends?
