Abstract: An improved method and device for connecting Ethernet network devices at desired settings, including speed and duplex mode. The connected devices include a local device and a link partner device. At least the local device will include auto-negotiation and parallel detection capabilities, along with the decision steps to establish a matched connection, or to fail the connection. The steps include determining and storing the supported device abilities. Parallel detection is performed, and if the link partner device supports auto-negotiation, then a highest compatible connection is established, or a failed connection is indicated as appropriate. If a parallel detect fault occurs, then a failed connection is also indicated. If no parallel detection faults, then the local device is checked for an auto-mode setting. If in auto mode, then the stored link partner abilities are retrieved and the local device is set. If not in auto mode, then the local device is set to user specified settings.
