As your list of flows in br-int bridge. I don’t see any flow relevant sfc. So maybe your openvswitch-agent can not load sfc extension sucessful.
Please check log of ovs-first. If right, there is a message like “ loaded extensions [‘sfc’]”.
If the list extensions above is None. So the extension is not loaded.

Hi Pham,
I am able to create the port chain now. However, I cannot see it running.
My scenario is simple with 3 VMs: VM1---<net1>--VM2--<net2>--VM3 (Please note: it is not working with single network as well)
I followed the following steps:
openstack port create --no-security-group --disable-port-security --network sfcnet1 net1p1vm1
openstack port create --no-security-group --disable-port-security --network sfcnet1 net1p2vm2
openstack port create --no-security-group --disable-port-security --network sfcnet2 net2p1vm2
openstack port create --no-security-group --disable-port-security --network sfcnet2 net2p2vm3
openstack server create --nic port-id=net1p1vm1 --image cloudUb16 --flavor m1.large vm1
openstack server create --nic port-id=net1p2vm2 --nic port-id=net2p1vm2 --image cloudUb16 --flavor m1.large vm2
openstack server create --nic port-id=net2p2vm3 --image cloudUb16 --flavor m1.large vm3
openstack sfc port pair create --ingress net1p1vm1 --egress net1p1vm1 PoP1
openstack sfc port pair create --ingress net1p2vm2 --egress net2p1vm2 PoP2
openstack sfc port pair create --ingress net2p2vm3 --egress net2p2vm3 PoP3
openstack sfc port pair group create --port-pair PoP1 PPGp1
openstack sfc port pair group create --port-pair PoP2 PPGp2
openstack sfc port pair group create --port-pair PoP3 PPGp3
openstack sfc flow classifier create --protocol icmp --ethertype IPv4 --source-ip-prefix 10.10.10.6/32 --destination-ip-prefix 20.20.20.9/32 --logical-source-port net1p1vm1 --logical-destination-port net2p2vm3 FCx

Due to this error, I am unable to delete the existing chain. I am using openstack queens Full installation. Please let me know how to triage this issue.
