Kals, OpenFlow Specification v1.3.2 If a bucket directs a packet explicitly out the ingress port, this packet clone is dropped. If the controller writer wants to forward out the ingress port, the group must include an extra bucket which includes an output action to the OFPP_IN_PORT reserved port.
>From what I understand the virtual / reserved port has to do with how devices are implemented. Use the virtual / reserved OFPP_IN_PORT if you want to send traffic out the ingress port. More interesting questions are, "In order to forward to OFPP_IN_PORT must I define a bucket with an action list that includes a single output to OFPP_IN_PORT? Or can I include this output action in the action list of other buckets?" I would assume the first to be true, and test for the second (on a per device basis) if I really need the function. - Jonathan On Thu, Oct 16, 2014 at 2:48 AM, tech_kals Kals <tech.k...@gmail.com> wrote: > Hi Experts, > > when i go through openflow spec 1.3.1, i am not able to understand the > following lines from 5.6.1.
