ABSTRACT:
The present invention has as its object to provide a frame relay switching node for enabling the performance of fault traces without causing insufficiency in the trace area. To achieve this object, in the case where the discarding of a frame has been performed by the frame reception processing section or by the relay frame reception processing section, or in the case where the loss of a frame has occurred within the relay frame reception processing section, the contents of the discarded or lost frame are reported to the frame relay trace control section. The frame relay trace control section is made to set within the trace area only the contents and the discard factors of frames that have been discarded or lost.
