Hello,
I'm seeing a weird flow mod issue in Destiny but not in Zaku.
I'm running the following code:
flow = {}
flow[core.DL_TYPE] = ethernet.IP_TYPE
flow[core.DL_SRC] = packet.src
flow[core.NW_SRC] = packet.next.srcip
flow[core.NW_DST] = packet.next.dstip
flow[core.NW_PROTO] = ipv4.TCP_PROTOCOL
flow[core.TP_SRC] = packet.next.next.srcport
flow[core.TP_DST] = packet.next.next.dstport
actions = [
[openflow.OFPAT_SET_DL_DST, inst.Agents[dpid]['mac']],
[openflow.OFPAT_SET_NW_DST, inst.Agents[dpid]['ip']],
[openflow.OFPAT_SET_TP_DST, TCP_REDIRECT_PORT ],
[openflow.OFPAT_OUTPUT, [0, inst.Agents[dpid]['inport']]]
]
print "----------------------------------"
print actions
print packet
print ip_to_str(packet.next.srcip)
inst.install_datapath_flow(dpid, flow, CACHE_TIMEOUT,
openflow.OFP_FLOW_PERMANENT, actions,
bufid, openflow.OFP_DEFAULT_PRIORITY,
inport, buf)
print "----------------------------------"
And I see the exact same output versions:
----------------------------------
[[5, array('B', [0, 0, 0, 0, 0, 4])], [7, 2189370920], [10, 9877], [0, [0, 3]]]

130.127.38.36
----------------------------------
Though the when I dump the flows at the switch Zaku install:
cookie=0x0, duration=3.213s, table_id=0, n_packets=1, n_bytes=74,
idle_timeout=5,tcp,dl_src=00:00:00:00:00:03,nw_src=130.127.38.36,nw_dst=130.127.39.5,tp_src=9877,tp_dst=37857
actions=mod_dl_dst:00:00:00:00:00:04,mod_nw_dst:130.127.38.40,mod_tp_dst:9877,output:3
Where destiny installs:
cookie=0x0, duration=1.371s, table_id=0, n_packets=1, n_bytes=74,
idle_timeout=5,tcp,dl_src=00:00:00:00:00:03,nw_src=130.127.38.36,nw_dst=130.127.39.5,tp_src=9877,tp_dst=57759
actions=mod_dl_dst:00:00:00:00:00:04
Any ideas here?
Thanks,
Aaron
