Is there any work around or changes that i can make for ip

Hi,
i have ovs-controller with default setting (ovs-controller -v
ptcp:6633).
on xenserver host with ovs
*ovs-vsctl get-fail-mode xenbr0*
*secure*
I set it to secure mode to test that host should not use vswitchd for flows
and forward it to controller for generating flow .*
