<p>A loop network hub port (300) with an automatic bypass feature. The automatic bypass feature causes the hub port (300) to enter a bypass mode upon detection of a specified loop initialization sequence (316) from a node port (310) attached to the hub port (300). The hub port (300) does not propagate loop failure initialization data generated by the attached node port (310) upon failure of a data channel from the hub port (300) to the node port (310). The hub port (300) replaces loop initialization data with buffer data (324) and conceals the node port (310) failure from the remainder of the loop. Upon detection of the loop failure initialization sequence received from the node port (310), the hub port (300) enters a bypass mode, connecting input (302) to the output (328) of the loop until a recovery sequence is received.</p> |
