Abstract:
A quarantine device 1 performs processing on a network provided with a VLAN-aware Layer 2 Switch 7. The quarantine device 1 includes a terminal detection unit 11 that, when a single terminal is connected to a specified port of the Layer 2 Switch 7 through a VLAN-unaware hub, detects a connection of a new terminal 4 to the hub, and a switch control unit 12 that, upon detecting the connection of the new terminal 4, configures the specified port as a trunk port and, furthermore, configures a first VLAN, which transfers only Ethernet frames having preset tags attached thereto, and a second VLAN, which transfers only Ethernet frames having no tags attached thereto, on the specified port.
