A flushing processing unit and method of a switching device in a network using Spanning Tree Protocol (STP). The method includes determining, by a switching device, whether there is a failure link; when there is the failure link, determining, by the switching device, which one of a root port and a designated port connects to the failure link; when it is determined that the root port connects to the failure link, changing, by the switching device, a filtering database and changing port information of a host address registered to the root port into preset alternate port information; and sending, by the switching device, a Transmission Control Protocol (TCP) message through an alternate port.
