This is all very confusing naming-wise, and I at least have no idea what
the configuration is right now. Please lets avoid names such as "eth<N>"
for the purposes of this conversation.

Also, since the chassis is apparently not labelled I don't think it
helps to talk about what things might be labelled if they were. Perhaps
you could take a photo and annotate it up with some names for clarity.

Please can you confirm:

     1. That the physical port associated with the "management
        interface" Ethernet port is wired into the switch.
     2. That the first physical non-management Ethernet port is also
        wired into the switch.
     3. The precise MAC address associated with both of those, in those
        terms (not in terms of the names Linux might have chosen, nor
        whatever might or might not be stencilled on the case)
     4. That the BIOS is configured such that:
             A. all AMT/lightsout/etc management traffic uses the
                management interface Ethernet port;
             B. the management port is not visible to the Operating
                System.
             C. the non-management port is configured solely for the use
                of the Operating System and will never be interfered
                with by any BIOS activity;
