Methods and systems are providing for configuring a port on a network device for communication with a port on a remote device. In one example, the network device receives, by a local port, a message from a physical coding sublayer (PCS) transmitter on the remote partner device. In one aspect, a port configuration module partitions the port to transfer data on a plurality of sub-ports each having a second data transfer rate if it is determined, by the network device that a local PCS receiver failed to align data received in the message. In another aspect, the port configuration module aggregates the plurality of sub-ports of the port to transfer data on a port having the first data transfer rate if it is determined, by the network device, that the local PCS receiver detected a code violation error in the message on at least one of the plurality of sub-links.
