[openstack-dev] [neutron][SFC]

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 ...

neutron flow-classifier-create --ethertype IPv4 --source-ip-prefix
22.1.20.1/32 --destination-ip-prefix 172.4.5.6/32 --protocol tcp
--source-port 23:23 --destination-port 100:100 FC1

returns: neutron flow-classifier-create: error: argument
--logical-source-port is required
Try 'neutron help flow-classifier-create' for more information.

 neutron port-pair-create --ingress=p1 --egress=p2 PP1
404 Not Found

The resource could not be found.

Neutron server returns request_ids:
['req-1bfd0983-4a61-4b32-90b3-252004d90e65']

neutron --version
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 ?

Regards
