Hi, Iwase. Thanks for answering.
Actually, I've explicitly added the types of MultipartReply messages as
the code you shown. Unfortunately, I still don't see any of them (even
though they exist). The trace below shows what I'm talking about:

As a final point, here is the event handler:

], 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)
