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 ?
