Open Stack

Thanks Julia,
My aim here to chk the for any kind of port binding or grouping inorder to
achived redundancy at the baremetal port level.
So scenarion as desired or which i am trying to bring up is :
I have an openstack controller computer setup(simple openstack)
On top of this I am provisioning baremetal node . On this baremetal node i
have one cable connected to one of the port from the switch. We inform
neutron about it before we go for server create. It works and we are able
to see the nodes getting added.
So on the same server we are trying to enable port binding , which we are
not able to do it.
If using cloud init which shall be passed during the server created then
what can be the standard configuration for it ? Or how to move forward?
