Alioune,
The logical-source-port refers to a Neutron port of the VM that
originates the traffic that is to be processed by the port-chain.

Thanks Mohan,
After setting service_plugins and adding sfc tables to neutrondb, I can create port-pair, port-pair-group but classifier creation still claim a logical-source-port parameter.
neutron flow-classifier-create --ethertype IPv4 --source-ip-prefix 55.55.55.2/32<http://55.55.55.2/32> --destination-ip-prefix 55.55.55.9/32<http://55.55.55.9/32> --protocol tcp --source-port 22:22 --destination-port 1:65000 FC1
ERROR:
neutron flow-classifier-create: error: argument --logical-source-port is required
Try 'neutron help flow-classifier-create' for more information.
Please someone can explain what does --logical-source-port correspond to ?
Does the classifier require port-create like SF ?

Alioune,
networking-sfc resources not installed / not reachable , If installation is okay, Possibly you may missed service_plugins entry in neutron.conf ( in case of manual networking-sfc installation)
it should be ,
service_plugins = neutron.services.l3_router.l3_router_plugin.L3RouterPlugin,networking_sfc.services.flowclassifier.plugin.FlowClassifierPlugin,networking_sfc.services.sfc.plugin.SfcPlugin
and restart q-svc services in screen -x
Thanks.,

I've switched from devstack to a normal deployment of openstack/mitaka and neutron-l2 agent is working fine with sfc. I can boot instances, create ports.
However I can not create neither flow-classifier nor port-pair ...

4.1.1
p1,p2,p3,p4 have already been created, I can ping instances attached to these ports.
Since I've not installed networking-sfc, are there additional config to set in neutron config files ?
Or is it due to neutron-client version ?

neutron agent not able to fetch details from ovsdb . Could you check below options 1.restart ovsdb-server and execute ovs_vsctl list-br 2. execute ovs- vsctl list-br manually and try to check error.
3. Could be ovs cleanup issue , please check the output of sudo service openvswitch restart and /etc/init.d/openvswich** restart , both should be same
Thanks.,

Hi Alioune and Cathy,
For devstack on ubuntu14.04, the default ovs version is 2.0.2, so there was the error as Alioune said.
Do we need to install speical ovs version in networking-sfc devstack plugin.sh?

Hi Alioune,
Which OVS version are you using?
Try openvswitch version 2.4.0 and restart the openvswitch-server before installing the devstack.

Probleme with OpenStack SFC
Hi all,
I've installed Openstack SFC with devstack and all module are corretly running except the neutron L2-agent
After a "screen -rd", it seems that there is a conflict between l2-agent and SFC (see trace bellow).
I solved the issue with "sudo ovs-vsctl set bridge br protocols=OpenFlow10,OpenFlow11,OpenFlow12,OpenFlow13" on all openvswitch bridge (br-int, br-ex, br-tun and br-mgmt0).
I would like to know:
- If someone knows why this error arrises ?
- is there another way to solve it ?
Regards,
