if the switch runs in the fail secure mode then flow will be permanent (hard time out =0 and idle time = 0). To change the mode of ovs to fail secure mode, you could use :

sudo ovs-vsctl set-fail-mode br0 secure

it does not worked. After i stop the controller the switch's dump-flows shows no flow entries.

could you give me details for the installed flow and the output of ovs-vsctl show and ovs-ofctl dump-flows <switch>.
