This object specifies the QoS profile applied to mirrored traffic as it is associated with a particular forwarding class at the mirror destination. An admin configures this so that copied traffic sent to the monitoring destination is treated with the intended queuing/priority profile rather than defaulting to whatever profile happens to apply. For example, leaving tMirrorDestinationFCProfile at its default value of out means mirrored packets inherit the standard out profile of the associated forwarding class unless explicitly overridden.
