A hub port (400) in a loop network is disclosed. The hub port (400) includes a hub data source (402), first and second detect circuits (414,420), and a processor (416). The hub data source (402) supplies data to the hub port (400) from the loop network. The first detect circuit (414) is configured to detect a first sequence from an attached node port (408) establishing a loop circuit. The second sequence from the attached node port (408) indicates to terminate the loop circuit. The processor (416) is configured to receive the first sequence from the first detect circuit (414). Further, the processor (416) operates to close a detect window and to increment a sequence origination count, if the detect window is open. The second detect circuit (420) is configured to detect the second sequence from the hub data source (402) confirming the termination of the loop circuit.
