A switching apparatus for use in a network includes a packet reception processing unit which generates a reply packet as a response to a request packet having a virtual local area network tag and transmitted for a ping test via a network to the switching apparatus, and sets the same priority class in a virtual local area network tag of the reply packet as that in the virtual local area network tag of the request packet, wherein the switching apparatus performs priority control on the reply packet based on the priority class in the virtual local area network tag of the reply packet.
