Abstract
A hub port in a Fibre Channel loop for detecting and bypassing attached node ports in an OLD-PORT state is disclosed. The hub port includes a hub data source, a detect circuits, and an output control circuit. The hub data source supplies data to the hub port from a Fibre Channel loop. The detect circuit is configured to detect a valid non-Arbitrated Loop sequence from an attached node port indicating that the node port is in an OLD-PORT state. The output control circuit operates to bypass the node port from the loop when the valid non-Arbitrated Loop sequence is detected.
