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-noha/scenario.description.rst

Our SFC topology:

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:

Flow table:

trace flow:

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
