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.
