Hi all,
I want to manually set a flow for test. The switch sends a packet_in message to
pox controller.
This is the code:
from pox.core import core
import pox.openflow.libopenflow_01 as of
from pox.lib.revent import *
from pox.lib.addresses import IPAddr, EthAddr
from collections import namedtuple
from pox.lib.util import str_to_bool, dpid_to_str
from pox.lib.packet.ipv4 import ipv4
from pox.lib.packet.ethernet import ethernet
from pox.lib.packet.tcp import *
from pox.lib.packet.udp import *
import os
log = core.getLogger()
class Test_output_port (EventMixin):
def __init__ (self):
self.listenTo(core.openflow)
def _handle_ConnectionUp (self, event):
packet = event.parsed
msg = of.ofp_flow_mod()
msg.match = of.ofp_match.from_packet(packet, event.port);
msg.buffer_id = event.ofp.buffer_id
msg.idle_timeout = 10
msg.idle_timeout = 30
msg.actions.append(of.ofp_action_output(port = 1))
msg.data = event.ofp
event.connection.send(msg),
def launch ():
'''
Starting the Firewall module
'''
core.registerNew(Test_output_port)
When test, it shows the following error. If anybody knows the reason, and can
give some help, I will appreciate.
