摘要： In an L2 switch having a VLAN function for configuring a layer 2 network in a star topology, a mesh topology, a ring topology, or the like, a VLAN functional portion maps a frame to a predetermined VLAN, a frame classifying portion assigns to the frame a first tag indicating a priority, and a policing portion assigns to the frame a second tag indicating whether or not the frame can be discarded. Also, an OAM monitor inserts a monitoring frame to the VLAN.

摘要： A transmission device is connected to a layer 2 switch through a transmission path at one side, and to a relay transmission path at the other side. The transmission path includes a transmission path of a active system and a transmission path of a stand-by system. When failure occurs in the transmission path of the active system, the transmission device forcibly shuts down the transmission path of the active system upon detection of link down, to stop packet transmission, and causes the layer 2 switch to perform MAC address flush. The transmission device then switches the transmission path of the stand-by system to the active system, and transmits packets through the transmission path that has become the active system as a result of switching. The layer 2 switch performs MAC address learning to set a port, thereby maintaining communication even after occurrence of the failure.
