Oops. It was in the original code that was deleted by mistak later.
Yes. It inmproved but still the entry is missing my match filelds
with this updated flow, the entry installed
cookie=0x0, duration=147.754s, table=0, n_packets=0, n_bytes=0, idle_age=147,
dl_type=0x8000 actions=NORMAL
But now pin works and subsequently, l2_learning can add aditional flows that
look like

Please see if I miss anything such that my match fileld are not added in the
flow
My code:
My code:
def _vn_addNormalFlow(self, vn_context):
print 'Adding VN flow for dpid %s' %(vn_context["dpid"])
print "ip converted :",IPAddr(vn_context["src_ip"])
print "ip input :", vn_context["src_ip"]
msg = of.ofp_flow_mod()
msg.flags = of.OFPFF_CHECK_OVERLAP
msg.command = of.OFPFC_ADD
# msg.match.nw_src = IPAddr(vn_context["src_ip"])
msg.match.nw_src = IPAddr("192.167.10.10")
msg.match.nw_dst = IPAddr("192.167.20.10")
# msg.match.nw_dst = IPAddr(vn_context["dst_ip"])
msg.match.dl_type = 0x8000
msg.match.nw_proto = vn_context["proto"]
# msg.match.tp_src = vn_context.tcp_src
msg.match.tp_dst = vn_context["tcp_dst"]
print "tp_dst:",msg.match.tp_dst
msg.actions.append(of.ofp_action_output(port = of.OFPP_NORMAL))
# core.openflow.sendToDPID(str_to_dpid(vn_context["dpid"]),msg)
con = core.openflow.getConnection(str_to_dpid(vn_context["dpid"]))
con.send(msg)
return True

Your first problem is that you need to specify dl_type = 0x0800 if you want to
match IP addresses and TCP/UDP ports.
