Hi Mahdieh,
Excuse me for jumping in.

Hi, Fujimoto
Thank you very much for the prompt reply. It works.
But I have another problem in developing my app. In my app when I'm installing rules on tables, I
have a rule for two situations in a switch:
1. when a packet is incoming to in_port_1 and will go to out_port_2
2. when a packet is incoming to in_port_2 and will go to out_port_2
should I have two separate rules for these situations? May I have a common action for them? Is there
any ryu action for changing the input_port field in ovs switch, like this:
» ovs-ofctl add-flow br0 in_port=2,actions=load:0->NXM_OF_IN_PORT[],2
How about using OFPActionSetField?
This action is almost equivalent to "load" action of OVS.
http://ryu.readthedocs.io/en/latest/ofproto_v1_3_ref.html#ryu.ofproto.ofproto_v1_3_parser.OFPActionSetField
If you want to use "load" action of OVS via Ryu, please refer to the following
document.
http://ryu.readthedocs.io/en/latest/nicira_ext_ref.html#ryu.ofproto.ofproto_v1_3_parser.NXActionRegLoad
Thanks,
Iwase
Thanks

Hi, Mahdieh
You can use "ofproto.OFPP_IN_PORT" to do it.
actions = [parser.OFPActionOutput(ofproto.OFPP_IN_PORT)]
self.add_flow(datapath, 0, match, actions)
Then, the flow shown below will be installed.
$ovs-ofctl -O OpenFlow13 dump-flows s1
OFPST_FLOW reply (OF1.3) (xid=0x2): cookie=0x0, duration=2.975s,
table=0, n_packets=13,
n_bytes=1026, priority=0 actions=IN_PORT
Thanks,
Fujimoto

Hi,
I want an ovs switch outputs a packet to its receiving port, but in ovs doc
I read:
actions=[action][,action...]
port
output:port
Outputs the packet to OpenFlow port number port. If
port is the packet's
input port, the packet is not output.
so with bellow Ryu code:
» actions = [ofproto_parser.OFPActionOutput(output_port)]
when input_port== output_port, the packet is dropped.
I find a new action in ovs :
in_port
Outputs the packet on the port from which it
was
received.
but I can't find this action in Ryu... could you please help me to write a
code like this:
» if (in_port == port):
actions=[ofproto_parser.OFPActionInPort()]
I'm using ovs 2.7 and openflow 1.3
Thanks in advance
