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
Thanks
