You have to do it manually. It was expected that a higher-level API would be implemented that might be a reasonable place to implement such a feature, but such has never materialized.
You could hack it in yourself, by patching the Connection.send() method to check the outgoing data for flow-mods, which isn't particularly elegant. A cleaner approach is to implement your own send_flow_mod() function or something and have this do whatever you need before forwarding on to Connection.send(). Of course, if you were using other components, they'd need to know to call this when appropriate. -- Murphy On Aug 4, 2014, at 5:17 AM, Adam Pavlidis <adampavli...@gmail.com> wrote: > Hello, > I am trying to code a module that need to performs some action when other > modules (or the same module that is beside the point) install a flow rule on > a switch.
