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

I cannot see any relevant flow entries and the port chain is not working.
