The following code should work as you expect.
=
import logging
import struct
import array
from ryu.controller import handler
from ryu.controller import ofp_event
from ryu.ofproto import ofproto_v1_2
from ryu.ofproto import ofproto_v1_2_parser
from ryu.base import app_manager
LOG = logging.getLogger('ryu.app.l2')
class L2Switch(app_manager.RyuApp):
OFP_VERSIONS = [ofproto_v1_2.OFP_VERSION]
def __init__(self, *args, **kwargs):
super(L2Switch, self).__init__(*args, **kwargs)
@handler.set_ev_cls(ofp_event.EventOFPPacketIn, handler.MAIN_DISPATCHER)
def packet_in_handler(self, ev):
msg = ev.msg
dp = msg.datapath
for f in msg.match.fields:
if f.header == ofproto_v1_2.OXM_OF_IN_PORT:
in_port = f.value
actions = [dp.ofproto_parser.OFPActionOutput(dp.ofproto.OFPP_FLOOD, 0)]
out = dp.ofproto_parser.OFPPacketOut(
datapath=dp, buffer_id=msg.buffer_id, in_port=in_port,
actions=actions)
LOG.debug("Sending message out %s", out)
dp.send_msg(out)
