Abstract
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.
