Hi Vinay,
You can use EventSwitchEnter and EventSwitchLeave.
(Note that this API is supported only by OpenFlow 1.0 and 1.3)
----------
from ryu.base import app_manager
from ryu.controller.handler import set_ev_cls
from ryu.topology import switches
from ryu.topology.event import EventSwitchEnter, EventSwitchLeave
class SwitchEventApp(app_manager.RyuApp):
_CONTEXTS = {
'switches': switches.Switches,
}
@set_ev_cls(EventSwitchEnter)
def _ev_switch_enter_handler(self, ev):
print('enter: %s' % ev)
@set_ev_cls(EventSwitchLeave)
def _ev_switch_leave_handler(self, ev):
print('leave: %s' % ev)
----------
Regards,
Satoshi
