3Set the type of the application image file to change the type of a boot file or order in which the boot files are selected.

The dual image function is available with the router. By default, the system defines and attempts to boot in order with three boot files: main, backup, and secure, provided they are available from Flash memory. If the router fails to boot with the secure boot file, it prompts the boot failure.

The following table gives default names and types of the boot files.

Table 19 Default names and types of the boot files

Boot file

File name

File type

 

 

 

Main boot file

main.bin

M

Backup boot file

backup.bin

B

Secure boot file

secure.bin

S

 

 

 

Note that:

The application images for system boot can be type M, B and S, but not type N/A. You can store them in Flash memory, but only one for each. For example, if an M+B file exists, it is impossible to have another M or B file. If you change the file type of another file to B, the M+B file becomes a type M file.

You can modify the file name of an application image in Flash memory using the command after it boots.

You cannot modify the file type of the type S application image file, but you can modify the file type of type M/B and N/A application image files in the Boot ROM menu or using commands after the application image boots.

Secure boot file is the last resort for system boot. You can download it in the Boot ROM menu and must name it secure.bin. However, you cannot modify this file or change the type of another file to S. If you change the name of the secure boot file with the rename command after the system boots, the file is removed from Flash memory. To use the secure boot file after that, you need to download it again.

Select <3> in Boot Menu. The console screen displays the following menu, provided four application image files have existed in Flash memory:
