A distributed fabric system has distributed line card (DLC) chassis and scaled-out fabric coupler (SFC) chassis. Each DLC chassis includes a network processor and fabric ports. Each network processor of each DLC chassis includes a fabric interface in communication with the DLC fabric ports of that DLC chassis. Each SFC chassis includes a fabric element and fabric ports. A communication link connects each SFC fabric port to one DLC fabric port. Each communication link includes cell-carrying lanes. Each fabric element of each SFC chassis collects per-lane statistics for each SFC fabric port of that SFC chassis. Each SFC chassis includes program code that obtains the per-lane statistics collected by the fabric element chip of that SFC chassis. A network element includes program code that gathers the per-lane statistics collected by each fabric element of each SFC chassis and integrates the statistics into a topology of the entire distributed fabric system.
