One embodiment relates to a method for automated correction of duplex mismatches. A duplex mismatch is detected at a port of a network device, and characteristics of the duplex mismatch are determined. The configuration of the mismatched port is automatically modified based upon said characteristics. Another embodiment relates to an apparatus for automated correction of duplex mismatches. The apparatus includes a duplex mismatch detector and an automated duplex mismatch fixer. The duplex mismatch detector is configured to detect a duplex mismatch at a port of a network device and to determine characteristics of the duplex mismatch. The automated duplex mismatch fixer is configured to modify a configuration of the mismatched port based upon said characteristics. Other embodiments and features are also disclosed.
