Dear all,
I want to send the packet out of the switch port and I write the code.
# Method for just sending a packet to any port (broadcast by default)
def send_packet (event,dst_port):
msg = of.ofp_packet_out(in_port=event.ofp.in_port)
if event.ofp.buffer_id != -1 and event.ofp.buffer_id is not None:
# We got a buffer ID from the switch; use that
msg.buffer_id = event.ofp.buffer_id
else:
# No buffer ID from switch -- we got the raw data
if event.ofp.data:
# No raw_data specified -- nothing to send!
return
msg.data = event.ofp.data
msg.actions.append(of.ofp_action_output(port = dst_port))
event.connection.send(msg)
## Create packet flow
def _handle_PacketIn (event):
packet = event.parsed
if packet.src == "00:00:00:00:00:01":
send_packet(event, 2)
else:
send_packet(event, 3)
def launch ():
core.openflow.addListenerByName("PacketIn", _handle_PacketIn)
When packet arrive at switch although it have mac address
"00:00:00:00:00:01" , it always go to the else condition
" else:
send_packet(event, 3)"
Please give me some suggestion
