To provide a switch device and a control method of the switch device which reduce a burden on a manager in an FCoE communication. A switch device relays the FCoE communication between a storage and a server disposed in an internal network and a FCF disposed in an external network. A reception port receives, from the FCoE, information of an external VLAN in the external network in response to a transmission request for information of a virtual network used in the FCoE communication. A protocol processing unit selects an internal VLAN, corresponding to the external VLAN, in the internal network. A transmission port notifies an end node of information of the internal VLAN as information of the VLAN used in the FCoE communication. A packet processing unit relays the FCoE communication between the end node and the FCF based on the internal VLAN and the external VLAN.
