Hi everybody.
I can't receive MultipartReply messages from switches, even though I had
defined the handler below and watched those messages using wireshark.
Does anybody have any idea about what is going on?
---
@set_ev_cls(ofp_event.EventOFPMultipartReply, [HANDSHAKE_DISPATCHER,
CONFIG_DISPATCHER, MAIN_DISPATCHER])
def switch_multipart_reply_handler(self, ev):
multipart_reply = ev.msg
datapath = ev.msg.datapath
print '>>> openflow %s MultipartReply message has been received from swich
%i' %(self.print_version(echo_request.version), datapath.id)

Here is the trace of execution of ryu using the 'SwitchCommander', an
application built to watch some of the OpenFlow messages received by the
controller.
