1. A system for negotiating Ethernet settings in a network, said system comprising:

  • a first network device and a second network device;

    an intermediate device connected to said first network device and said second network device, said intermediate device comprising;

    a first network interface coupled to said first network device and a second network interface coupled to said second network device, said first network interface and said second network interface each comprising an Ethernet PCS sub-layer;

    a first switch coupled to said first network interface, a management module, and said second network interface, said first switch for passing first auto-configuration codes to said management module and said Ethernet PCS sub-layer of said second network interface until said management module detects that a first auto configuration is completed;

    a second switch coupled to said second network interface, said management module, and said first network interface, each of said first and second switch for passing one or more second auto-configuration codes to said management module and said Ethernet PCS sub-layer of each of said second and first network interface, respectively, until said management module detects that said first and a second auto-configuration is completed; and

    said management module programming said first and said second switch into a data mode and configuring a protocol stack of said intermediate device to be compatible with said first and second auto-configuration codes once said management module detects that said first and second auto-configuration are completed.
