This read-create value is the 802 (MAC) destination address that incoming frames' destination address is compared against, subject to wildcarding defined by a separate mask object, with matching frames potentially subject to this filter entry's associated action. An admin sets this to the specific destination MAC address, or a masked range of addresses, that should trigger this filter's associated processing action. For example, setting this object to a specific device's MAC address configures the filter to match traffic destined specifically to that device.
