Open Stack

Hi all,

I have been trying out networking-sfc to create service function chain in Openstack. I could create all the port pairs, port-pair-groups, flow classifier and the chain but I could not see the packets on the desired hops.
I am trying to create a simple sfc with 3 VMs(vm1 to vm3) in the setup. I just want to check how it works. In my setup, vm1 is the Traffic generator(iperf) and vm3 is the traffic receiver(iperf server). Now, the  2 vms (vm2 and 3) are in the same network with vm1 and I want to move the iperf traffic from vm1->vm2->vm3. In order to achieve this, I have created 2 port pairs of vm2  and vm3 and both pairs are in separate port pair groups (PG1 and PG2), also created a Flow classifier FC1 and finally chain with PG1, PG2 and FC1.  Now my question is, is my setup correct in order to achieve the sfc result as I stated above? Do I need to include the vm1 in the port pair group?
Below is the flow classifier:

Is there any wiki with some example case explained with testing scenario?
