Hi everyone.
When I run simple_switch_14.py application in mininet environment, the
ping of hosts works just fine.
Then I change the following strings of code:
1) "from ryu.ofproto import ofproto_v1_4" to "from ryu.ofproto import
ofproto_v1_5"
2) "OFP_VERSIONS = [ofproto_v1_4.OFP_VERSION]" to "OFP_VERSIONS =
[ofproto_v1_5.OFP_VERSION]"
3) "out = parser.OFPPacketOut(datapath=datapath, buffer_id=msg.buffer_id,
in_port=in_port, actions=actions, data=data)" to "out =
parser.OFPPacketOut(datapath=datapath, buffer_id=msg.buffer_id,
match=parser.OFPMatch(in_port=in_port), actions=actions, data=data)"
it means that I am trying to run this application in openflow 1.5 version
environment.
I get following error:
EVENT ofp_event->SimpleSwitch14 EventOFPPacketIn
packet in 1 00:00:00:00:00:01 ff:ff:ff:ff:ff:ff 1
EventOFPErrorMsg received.

`-- data: version=0x6, msg_type=0xd, msg_len=0x38, xid=0x703a0cc
`-- msg_type: OFPT_PACKET_OUT(13)
so, I am wondering, why it generates error related to 'bad out port', what
has changed in 'out ports' or in 'actions' between v1.4 and v1.5 of
openflow protocols?
Cheers,
