Hi, I tried to run pyswitch component but it still does not see that the switches have been added into the network.only when i dont add IP address to the controller then i can see the switches communicate to the controller.
Inside the topology, i used node class which is to add the IP address of controller , defaultIP = "10.0.0.250" instead of loopback address, 127.0.0.1 Regards, Anthony On Sun, Jun 10, 2012 at 2:20 PM, Anthony Salim < [email protected]> wrote: > Hi, > > I am just using ovswitch from mininet and not starting any components.
