I started to remove switches and discovered one was causing issues. I have not yet investigated why.
What I am trying to accomplish is a proof of concept with 4 switches in a ring topology. Two of the four switches are connected to different subnets. So 192.168.0.x is connected to switch1 and 192.168.1.x is connected to switch3. All switches are controlled by a single controller, and the goal is to be able to dynamically reroute traffic between the subnets within the ring based on higher-level rules passed into the controller. So in normal traffic flows from switch1 to switch3, a rule can tell the controller to route switch1 to switch2 to switch4, for example. I basically have it working, I am now trying to get statistics setup to report on existing traffic flows.
