<p class="MsoNormal">Hi all,<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">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.
<o:p></o:p></p>
<p class="MsoNormal">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?
<o:p></o:p></p>
<p class="MsoNormal"><span style="color:#1F497D"> </span><o:p></o:p></p>
<p class="MsoNormal"><span style="color:#1F497D">Cathy> You only need to include VM2 in a port pair group. Traffic source and traffic destination do not need to be included in the chain’s port pair group, instead their IP addresses should be included in the
flow classifier so that the system knows which flow needs to go through the chain. Here is a link to thw wiki.</span><o:p></o:p></p>
