Hi, corey Sorry, I couldn't see the reconnection with your code, it seems to work.
Please confirm the followings: * Using the latest version of Ryu(4.17) * (If you use OVS,) Using the latest version of OVS(2.8.0) If confirmed, would you send me the whole of your code? Thanks, Fujimoto On 2017年09月25日 20:24, corey ross wrote:
Hello, I am trying to send and parse table feature message. This is my code: @set_ev_cls(ofp_event.EventOFPSwitchFeatures, CONFIG_DISPATCHER) def switch_features_handler(self, ev): """ Send miss-table flow entry to datapaths and send the table feature request. """ datapath = ev.msg.datapath ofproto = datapath.ofproto parser = datapath.ofproto_parser msg = ev.msg self.logger.info <http://self.logger.info>("switch:%s connected", datapath.id <http://datapath.id>) # install table-miss flow entry match = parser.OFPMatch() actions = [parser.OFPActionOutput(ofproto.OFPP_CONTROLLER, ofproto.OFPCML_NO_BUFFER)] self.add_flow(datapath, 0, match, actions) # send_table feature request stats = parser.OFPTableFeaturesStatsRequest(datapath, 0, []) datapath.send_msg(stats) @set_ev_cls(ofp_event.EventOFPTableFeaturesStatsReply, MAIN_DISPATCHER) def _table_features_handler(self, ev): """ It get the max entries for a table and store it in max_table_capacity. """ msg = ev.msg datapath = msg.datapath # print(msg.body) for stat in msg.body: if stat.table_id == 0: self.table_body[datapath.id <http://datapath.id>]['body'] = stat self.logger.debug('table_body: %s', self.table_body[datapath.id <http://datapath.id>])but as you can see when I run the program it causes the switches to reconnect:switch:2 connected switch:6 connected switch:7 connected switch:4 connected switch:1 connected switch:3 connected switch:5 connected switch:7 connected switch:6 connected switch:1 connected switch:4 connected switch:5 connected switch:3 connected switch:2 connectedWhat could be wrong? What is the correct way to request for table features (during) handshake?Thank you ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Ryu-devel mailing list Ryu-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/ryu-devel
