BCM57416 - Mismatching link speed between ports on a 2 port device is not supported.

  • 1.  BCM57416 - Mismatching link speed between ports on a 2 port device is not supported.

    Latest firmware for the BCM57416 Dual port 10GBASE-T card states:

     

      - Mismatching link speed between ports on a 2 port device is not supported. (Eg: 10G on port 1 and 25G on port 2, is not a supported speed combination.)

     

     

    Now, when we purchased these this was not a limitation issued.  I'm trying to get a clear reading on what this is saying.

     

    Does it mean -

     

    A) 1GB line on port (1) and a 10GB line on Port (2) OF THE SAME CARD is not supported 

     

    or

     

    B) 1 GB line on port (1) and a 10GB line on Port (2) OF THE SAME CARD and SAME PORT GROUP is not supported.


    or

    C)  none of the above and it's fine to run lines.

     

     

     

     

    The reason I ask is we utilize these and they are working as card with PORT 1 at 1GB and PORT 2 at 10 GB. We are trying to chase down an unrelated issue on the system and want to clear the cards of possible blame.
