Abstract:
A switch fabric controller comparator system (200) is provided for comparing the contents of a foreground port mapping memory (25) and a background port mapping memory (125). The switch fabric controller comparator system (200) includes the foreground port mapping memory (25), the background port mapping memory (125), and a switch fabric controller comparator (150). Routinely, the switch fabric controller comparator (150) compares the contents of the foreground port mapping memory (25) and the background port mapping memory (125) to determine if any discrepancy exists between the two memories as to which input ports are mapped to which output ports. If a discrepancy or error is found, an error signal is generated by the switch fabric controller comparator (150). The foreground switch fabric controller (24) may log the error signal and enable another signal in response.
