Abstract
A hub port in a Fiber Channel loop includes a hub data source, a loop initialization data detect circuit, and a loop initialization counter. The hub data source supplies data to the hub port from the Fiber Channel loop. The loop initialization data detect circuit is configured to detect valid loop initialization sequences from an attached node port and the hub data source. The loop initialization counter is configured to increment a count value of the valid loop initialization sequence from the attached node port if the loop initialization sequence from the node port does not match the valid loop initialization sequence from the hub data source. This state indicates that the loop initialization sequence is initiated by the attached node port.
