Abstract
A layer 2 switch network system includes a terminal, an edge switch, and a Radius server that notifies the edge switch of a temporary MAC address allocated to the terminal. The edge switch stores therein swap data for associating the temporary MAC address with a real MAC address. When receiving a MAC frame from the terminal, the edge switch replaces the real MAC address of a source set in the MAC frame with the temporary MAC address of the source. When transmitting a MAC frame to the terminal, the edge switch replaces the temporary MAC address of a destination set in the MAC frame with the real MAC address of the destination.

22. A layer 2 switch network system that includes a terminal, comprising:
-
a plurality of layer 2 switches including an edge switch that is located at an edge of a layer 2 switch network and serves as a wireless access point; and
a temporary-MAC-address notifying unit that notifies the edge switch of a temporary MAC address allocated to the terminal, wherein the edge switch stores therein swap data which associates a temporary MAC address acquired from the temporary-MAC-address notifying unit with a real MAC address, and, based on the swap data, replaces a real MAC address of a source set in a MAC frame with a temporary MAC address of the source on receipt of the MAC frame, and replaces a temporary MAC address of a destination set in a MAC frame with a real MAC address of the destination to transmit the MAC frame. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36)

37. A terminal device in a layer 2 switch network that includes a plurality of layer 2 switches including an edge switch located on an edge of the layer 2 switch network as a wireless access point, the terminal device comprising:
-
an interface;
a storage unit that stores therein a real MAC address and a temporary MAC address for identifying the interface;
a replacing unit that performs replacement between the real MAC address and the temporary MAC address; and
a communicating unit that communicates with the layer 2 switch networks using the temporary MAC address. - View Dependent Claims (38, 39, 40, 41, 42)
