Hi, Tomonori, In fact I have written 'super(MyApp, self).__init__(*args,
**kwargs)' in my __init__ function.
To make it simple, I just add start() in the ryu simple_switch_13.py, like this:
class SimpleSwitch13(app_manager.RyuApp):
OFP_VERSIONS = [ofproto_v1_3.OFP_VERSION]
def __init__(self, *args, **kwargs):
super(SimpleSwitch13, self).__init__(*args, **kwargs)
self.mac_to_port = {}
def start(self):
print "HELLO................."
super(SimpleSwitch13, self).start()
@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
self.logger.info("datapath in: %s", datapath.address[0])
But I still cannot see the log 'HELLO.............' outputted. So I am
confused. I run the simple_switch_13.py like this:
root@openflow:/home/workspace/ryu/ryu/app# ryu-manager simple_switch_13.py
loading app simple_switch_13.py
loading app ryu.controller.ofp_handler
instantiating app simple_switch_13.py
instantiating app ryu.controller.ofp_handler
datapath in: 10.10.0.36
datapath in: 10.10.0.35
datapath in: 10.10.0.33
packet in 295606521832913 74:25:8a:bf:22:3d 01:80:c2:00:00:0e 48
Do I miss something ?
Best Regards,
Kun Liu

Try something like the following code:
=
from ryu.base import app_manager
class ExampleApp(app_manager.RyuApp):
def __init__(self, *args, **kwargs):
super(ExampleApp, self).__init__(*args, **kwargs)
def start(self):
print "hello"
super(ExampleApp, self).start()
