Hi list,
Using OF 1.2 I'm trying to match different header fields of incoming packets.
Unfortunately on the in_port field seems to exist:
Code:
@set_ev_cls(ofp_event.EventOFPPacketIn, MAIN_DISPATCHER)
def packet_in_handler(self, ev):
msg = ev.msg
dp = msg.datapath
ofp = dp.ofproto
dpid = dp.id
pkt = packet.Packet(array.array('B', msg.data))
in_port = ''
eth_src = ''
eth_dst = ''
eth_type = ''
fields = msg.match.fields
print len(fields)
for f in fields:
if f.header == ofp.OXM_OF_IN_PORT:
in_port = f.value
print f.value
elif f.header == ofp.OXM_OF_ETH_SRC:
eth_src = f.value
print f.value
elif f.header == ofp.OXM_OF_ETH_DST:
eth_dst = f.value
elif f.header == ofp.OXM_OF_ETH_TYPE:
eth_type = f.value
print f.value
print 'in_port: {}, eth_src: {}, eth_dst: {}, eth_type:
{}'.format(in_port, eth_src, eth_dst, eth_type)
Output:
1 (#length of field)
4294967294 (# port no.)
in_port: 4294967294, eth_src: , eth_dst: , eth_type:
am I missing something?
Thanks,
Michael
