This object sets the scope of a mirror destination by choosing whether it accepts mirrored traffic only from sources on the same node, only from remote nodes reached via a mirroring service, or from both at once. An admin picks both when they want to combine locally mirrored ports with mirrored traffic funneled in from other routers into a single shared monitoring destination. For example, leaving tMirrorDestinationMirrorSourceType at its default of local(1) means only locally mirrored traffic on that node feeds this destination until it is changed to remote or both.
