Dear Sir, We are testing a simple SFC in OpenStack (Stein) + OpenDaylight (Neon) + Open vSwitch (v2.11.1). It's an all-in-one deployment. We have read the document: https://readthedocs.org/projects/odl-sfc/downloads/pdf/latest/ and https://github.com/opnfv/sfc/blob/master/docs/release/scenarios/os-odl-sfc-n... [image: image.png] Our SFC topology: [image: enter image description here] <https://i.stack.imgur.com/7QMWh.png> All on the same compute node. Build SFC through API: 1. openstack sfc flow classifier create --source-ip-prefix 10.20.0.0/24 --logical-source-port p0 FC1 2. openstack sfc port pair create --description "Firewall SF instance 1" --ingress p1 --egress p1 --service-function-parameters correlation=None PP1 3. openstack sfc port pair group create --port-pair PP1 PPG1 4. openstack sfc port chain create --port-pair-group PPG1 --flow-classifier FC1 --chain-parameters correlation=nsh PC1 Ping from client to server, but packet did not pass through firewall，open vswitch log show: [image: enter image description here] <https://i.stack.imgur.com/eucDz.png> Flow table: [image: enter image description here] <https://i.stack.imgur.com/cx3rJ.jpg> trace flow: [image: enter image description here] <https://i.stack.imgur.com/Jhi8M.png> Is there something wrong with the OpenStack instructions? It seems SFC proxy not work or there may be some bugs in "networking-sfc"? Thanks! Sincerely, Jhen-Hao
