A local switching method using a logical link ID (LLID) in an Ethernet passive optical network (EPON) system is disclosed. The local switching method includes a first step of an optical network unit (ONU) receiving and separating data inputted through a user port into a wide area network (WAN) traffic and a local area network (LAN) traffic, allocating the LLID according to a service for each traffic to the separated WAN traffic and LAN traffic, and transmitting the WAN traffic and LAN traffic with the LLIDs allocated thereto; and a second step of an optical line termination (OLT) receiving the WAN traffic and LAN traffic with the LLIDs allocated thereto transferred from the ONU, extracting a destination of the corresponding traffic through the LLIDs, and transmitting the respective traffic accordingly.
