This object controls the forwarding of unknown
unicast frames to this port. When set to true(1),
the switch will, upon receiving a frame with an
unknown unicast destination address from
another port, transmit the frame to this port.
When set to false(2), switch will filter
and not transmit said frames to this port.
Default value: false(2) for ports using
the security or monitor application;
true(1) for all other usage applications.
