Solution Verified - Updated -


  • when MAC address of existing NIC interface changes, the entry in host details can get duplicated
  • when trying to save any changes to the host details, it fails with error message:
    Some of the interfaces are invalid. Please check the table below.
  • It is not possible to delete the duplicates from GUI, because attempts to save the host details with deleted NICs fail with the same error
  • Can not register system with below error message.
