Creating sfc flow classifier without --logical-source-port dosen't work

steps to reproduce:
1. create network
2. create three ports sf_port, source_port, dest_port
3. create three instances with ports.
4. create flowclassifier (without --logical-source-port option flow classifier doesn't work)
(openstack) sfc flow classifier create --ethertype IPv4 --source-ip-prefix 10.0.0.5/32 --destination-ip-prefix 10.0.0.6/32 --protocol tcp --destination-port 80:80 FC_1
5. create port pairs using
(openstack) sfc port pair create --ingress=sf_port --egress=sf_port PP1
6. create port pair group
(openstack) sfc port pair group create --port-pair PP1 PG1
7. create port chain
(openstack) sfc port chain create --port-pair-group PG1 --flow-classifier FC_1 PC1
8 check communication between source_vm and dest_vm (doesn't work)

note: create ports with security group allow all rules
