Hi to everyone,
I need an help for my thesis,
I want to identify a control packet from Python RYU-controller. In other words:
How I can to do the following instruction?
If (I receive a OFPT_PACKET_OUT msg from ryu-controller)
do something (for example all control traffic from controller must mirroring
to an output port)
and How can I match this rule?
I saw in OpenFlow v1.3 specification that there is a ofproto.OFPP_CONTROLLER
reserved port: How can I use it as an ingress port?
>From OFv1.3 spec.: "OFPP_CONTROLLER: Represents the control channel with the
>OpenFlow controller. Can be used as an ingress port or as an output port.
When used as an output port, encapsulate the packet in a packet-in message and
send it using the OpenFlow protocol.
When used as an ingress port, identify a packet originating from the
controller."
Thanks for the help.
