Offhand, I think it should work. Which version of POX are you using, and if you're using dart, is it up to date?
A bunch of the handler stuff got rewritten semi-recently. I think there were some bugs, and it's possible there still are. Also... are you sure you're getting flow stats messages from the switch? You've verified they're on the wire using Wireshark or something? One thing you can do to help diagnose is to set the handler "manually" using core.openflow.addListener(pox.openflow.FlowStatsReceived, self._handle_openflow_FlowStatsReceived) or something like that. See if the handler fires then. -- Murphy On Oct 17, 2014, at 12:16 PM, Alison Chan <chan7...@kettering.edu> wrote: > Hello, > If I understand core.listen_to_dependencies correctly, it > automatically registers event handlers in a component if they are > named according to a scheme.
