Hi All,
I am trying to write a simple Ryu controller app which on receiving a
packet_in would reply back with a packet out with action=FLOOD. I found the
function provided in the simple_switch.py already does this. I have used
the same function as-is in my app (which handles other events as well,
hence i could not directly take simple_switch.py script). I am using 1.3 OF
version. I see the following error on controller console when a packet in
message arrives:
EVENT ofp_event->SndRcvRoleMsg EventOFPPacketIn
Traceback (most recent call last):
File "/usr/lib/pymodules/python2.7/gevent/greenlet.py", line 405, in run
result = self._run(*self.args, **self.kwargs)
File
"/usr/local/lib/python2.7/dist-packages/ryu-1.8-py2.7.egg/ryu/base/app_manager.py",
line 106, in _event_loop
handler(ev)
File "/home/openflow/ryu/ryu-master/role_msg_pin.py", line 71, in
_packet_in_handler
msg.in_port)
*AttributeError: 'OFPPacketIn' object has no attribute 'in_port'*
<Greenlet at 0xa62a0ec: <bound method SndRcvRoleMsg._event_loop of
<role_msg_pin.SndRcvRoleMsg object at 0xa62c36c>>> failed with
AttributeError
After browsing the code a bit, i could see that OFPPacketIn class really
does not have 'in_port' as attribute. Not sure what is wrong. Can someone
please help?
Thanks,
Nitish
