I'm using OVS

Is there way to disconnect port, thus putting it into DOWN state on VM,
using Openstack API ? This is important for *public clouds* when it can
be necessary to shutdown port of unmanaged (customer's) VM. The only
idea I have is to set admin_state_up to False and, actually, it's the
only command, which control port state.
As I mentioned earlier, it seems it was working in Kilo ("I have checked
the behavior of admin_state_up of Kilo version, when port admin-state-up
is set to False, the port status will be DOWN.") but Ocata shows another
behaviour, ignoring this parameter.
So, any ideas on how to shutdown port on VM using Openstack API?
