Pushing flows, groups, or meters via a northbound REST API to any controller in the team is
supported even if that controller is not the master of the given device. In that case, the controller
will delegate the request to the controller who is the master of the switch and the master controller
will handle the request. If the switch returns an error from the given request (for example, the
meters table is full), the switch responds to the owning controller with a proper Openflow error.
But when that error is sent back to the requesting controller, it is not parsed properly and results
in an error.
Action
If you are pushing a meter or group mod to a connected switch from a controller, that controller
must be the master in order to handle the errors correctly.
