1. A method for regulating link speed for performance enhancement and port diagnosis by a processor device, comprising:

  • in response to identifying an amount of errors in a communications link above a predetermined threshold, selectively reducing (n−

    1) an applicable transmission speed; and

    if errors identified at the reduced transmission speed are found to decrease, flagging a communications port incorporating the communications link as potentially dirty, and if the errors identified at the reduced transmission speed are found to remain constant, flagging the communications port as potentially bad.
