Hi,
Thanks for your reply kindly.
I tried your code. It can run to achieve my goal.
But i tried to add them to the function switch_features_handle of
simple_switch_13.
The result returned empty dict. Why?
@set_ev_cls(ofp_event.EventOFPSwitchFeatures, CONFIG_DISPATCHER)
def switch_features_handler(self, ev):
datapath = ev.msg.datapath
ofproto = datapath.ofproto
parser = datapath.ofproto_parser
match = parser.OFPMatch()
actions = [parser.OFPActionOutput(ofproto.OFPP_CONTROLLER,
ofproto.OFPCML_NO_BUFFER)]
self.add_flow(datapath, 0, match, actions)
switches = self.dpset.get_all()
mac_addresses = [(s[0],
s[1].ports[ofproto_v1_3.OFPP_LOCAL].hw_addr)
for s in switches]
print("mac_addresses {}".format(mac_addresses))
Thanks,
Regards,
Alan
