PURPOSE: A line interface statistics collecting method in a distributed processing high speed router is provided to quickly and effectively perform a line interface statistics collection request received from an operator terminal and a network management system by using a high speed router including line cards with a control processor, and stably operate the high speed router. CONSTITUTION: A data is initialized to collect a line interface statistics(S301) and comes in a standby state to wait for a statistics collection request from an operator terminal or a network management system(S302). When the line interface statistics collection request is received from the operator terminal(S303), a line card and a port number requested by the operator terminal are analyzed(S304), and a related transmission and reception counter information desired to be collected by the operator terminal is collected from control processors of the obtained line card(S305). The collected counter information is formatted to a form to be outputted to the operator terminal(S306), and the line interface statistics collection result is provided to the operator terminal(S307). When a line interface statistics collection request is received from the network management system, that is, when a message for an MIB(management information base) object data searching request is received(S308), the received message is analyzed and a PDU(Protocol Data Unit) is extracted(S309), and the requested statistics MIB is searched(S310). A related transmission and reception counter information is collected by using the searched information(S311), and the collected related transmission and reception counter information is combined(S312). The combined related transmission and reception counter information is converted into an MIB object information requested by the network management system and a PDU to be used when responding to the network management system is generated(S313). The MIB object data searching result using the generated PDU is provided to the network management system(S314).
