The NMS sets this object to 'createRequest' to establish a new trap host, sets any other columnar instances as needed, and then sets this object to 'valid' to initiate its operation. This can all be done in one PDU. If all default values are acceptable, the NMS can create this row by simply setting this single object to 'valid'. The NMS sets this object to 'invalid' to remove this row and terminate trap reporting to this host.
