Files Managed by the Router

BootWare file
The BootWare file is used to boot an application. A complete BootWare file includes two segments:
basic and extended.
Application files
By default, the MSR 20- 1 X routers define three application files for booting: main, backup, and secure.
The system selects these three files in sequence to start up the router. Currently only one application file
is stored in the Flash memory of the MSR 20- 1 X routers due to limited memory size. To change the file
selection sequence or modify an application file, refer to
Files on page
The details about the three application files are as follows:
Main file: The file used for booting by default. The default file name is main.bin and the file type is
•
M.
Backup file: The default file name is backup.bin and the file type is B. The system uses the backup
•
file when it fails to boot using the main file.
Secure file: The default file name is secure.bin and the file type is S. The system uses the secure file
•
when it fails to boot using the backup boot file. If the system fails to boot using the secure boot file,
it prompts a boot failure.
NOTE:
The application files for system boot can be type M, B, and S, but not type N (namely, types other than
•
type M, B, or S).
You can modify the name of an application file in storage after the application file is loaded. You cannot
•
modify the type of a type S application file, but you can modify the type of a type M, B, or N application
file using the BootWare menu or using commands after the application file is loaded.
The secure file is the last resort for system boot. You can download it in the BootWare menu and must
•
name it secure.bin. However, you cannot modify the type of this file or change the type of other files to
S. If you change the name of the secure file with the rename command after system boot, the file is
removed from the Flash memory and you need to download it again.
You can store type M, B, S files in storage devices, but only one for each type in each storage device. For
•
example, if a type M+B file exists in the Flash memory, there will be no type M or B file. If you change
the type of a file to B, the M+B file will become a type M file.
Configuration files
The configuration files store configuration information of the router.
