Hi,
I am trying to create a new packet that changes some fields from an
existing (received via packet_in) ethernet packet, adds a new vlan header
and then sends back (via packet_out) the packet to the switch, with the
same original ethernet payload....
At this moment I am solving this using some OF13 rules, but I would like to
know how to do this at the controller.
Reading about the packet library I know I can easily build a new ethernet
packet, with a vlan header after it, and that I can even add a bytearray to
the end of the original serialized and newly created packet... what I do
not know is how I can access the right position of the original received
packet that points me to the original ethernet packet's payload.
Could you give some insight on how this can be done?
Best regards,
Ricardo
