(54) Title: DIAGNOSTICS IN DISTRIBUTED FABRIC SYSTEM

(57) Abstract: 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 communic ation with the DLC fabric ports of that DLC chassis. Each SFC chassis
includes a fabric element and fabric ports. A communication link con
nects each SFC fabric port to one DLC fabric port. Each communica
tion 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 perlane 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 in
tegrates the statistics into a topology of the entire distributed fabric sy s
tem.
