Its ok now. I am using the following code and i am getting the *datapath id*
along with the rest of the information.
*@set_ev_cls(dpset.EventDP, MAIN_DISPATCHER)*
* def _event_dp_handler(self, ev): *
* self.logger.info <http://self.logger.info>("dp.id <http://dp.id>=%i,
dp.address=%s", ev.dp.id <http://ev.dp.id>, ev.dp.address) *
* for p in ev.ports:*
* self.logger.info <http://self.logger.info>("port_no= %s,
hw_addr= %s, interface= %s", p.port_no, p.hw_addr, p.name <http://p.name>)*
Is this method correct?. If there is a better way kindly indicate.
Thanks
Hadem
