Hi all, I've solved the error. In fact I did not create a router attached to the tenant subnet and according to neutron logs that was the first exception raised while creating port-chain. Now the port-chain has been created and some flows entries have been pushed in br-int. I think I could be interesting to update the wiki.
When running a ping from the source to the dst, I can see ICMP (request and reply) packets from the Tap interface of the source but I can not see them in the Taps of SFs. Is there a way to display packets (with wireshark or tcpdump ) going inbout and outbount of the SFs ?
