This MIB is used to configure those devices that support
boot-time hardware diagnostics.  It provides the reports 
about the respective diagnostic tests executed by the 
devices as well. 

Boot-time diagnostics are run after the ROMMON has 
transferred control to the start code of IOS and before 
any IOS subsystem has started. 

Such diagnostics may or may not include those that are 
destructive to the operation of IOS or communications
links that are serviced by IOS and, as such, must be run
before IOS has completed booting and before any subsystem
has started. 

During boot-up from either power-on or a reload, and
before IOS starts, a loop of all such diagnostics is executed
according to the following flow: 

     bank = current_bank 
     for index = 1 to number of diagnostics { 
        if diag[index] is configured AND armed for bank { 
          call diagnostic_function[index]; 
          store results in memory = structure.bank.index; 
        } 

After all the IOS subsystems have started, one can
use either the CLI or this MIB to query the status of the 
diagnostic tests for each bank. 

The diagnostic tests are tabulated on the CLI as
follows.

     FPGA(s) test       YES  FAILED       YES         NO 

     FPGA Diags: FPGA1:F, FPGA2-REG:P, FPGA2-SRAM:P, FPGA3:F


In the table above, there are 3 diagnostic_function 
categories: 

EDAC, EEPROM, and FPGA(s).   The FPGA category has 4
subtests one associated with FPGA1, two with FPGA2, and one
with FPGA3. 

The MIB shall be used to configure the diagnostic tests
to be run on each bank and read the results of the same.  The
selection of a particular bank to run the tests is hardware-
dependent.
