The first thing I'd do is write a simple application that just installs a flow with a timeout and then does nothing. Then I'd try some of the following:
1) run wireshark on the control connection and make sure the timeouts in the flow_mod look correct 2) leave the controller connected and see if the flows expire 3) try the same code on a different switch (e.g., Open vSwitch or the reference software switch) I'd hope one of those would tell me something interesting. :) Good luck! -- Murphy On Apr 11, 2012, at 1:45 PM, Weiyang Mo wrote: > Hi,all, > > I use "self.install_datapath_flow(dpid, attrs, 120, 120, actions, bufid, > openflow.OFP_DEFAULT_PRIORITY, inport, packet)" > to insert a flow-entry to my Pronto switch and I can see such flow-entries in > the flow-table. > > However the timeout doesn't work.
