Maintaining Software
The software maintenance process is the same for both the A6604 and the A6608. The A6608
is taken as an example in this chapter.
Software Components and Functions
Files
Three types of files need to be managed on the device. They are:
BootWare program file
Application file
Configuration file
BootWare Program File
The BootWare program file is used for booting the application when the router starts and is
stored in the flash memory. The entire BootWare program consists of a basic section and
extended section.
The basic section is used for the basic initialization of the system.
The extended section provides abundant human-computer interaction (HCI) functions and is
used to initialize interfaces and update the applications and the boot system.
After the basic section is loaded, you can load and update the extended section through the
menu of the basic section.
Application Files
The device supports the dual image function. By default, the system defines three types of
application files for boot.
Main application file (with the attribute of M)
Backup application file (with the attribute of B)
Secure application file (with the attribute of S)
These three types of application files are stored in a CF card. By default, they are written into
the built-in CF card before delivery.
If you have uploaded all the three types of application files into the built-in CF card, the system
will boot using these three files in order. For more information about application files, refer to
“
Maintaining Application and Configuration Files
” on page 6-32.
The following gives the default names and types of the application files and their priorities for system
boot.
Main application file. The default name is main.bin. It is the default application file used for
system boot.
Backup application file. The default name is backup.bin. When booting with the main
application file fails, the system boots using the backup application file.
Secure application file. The default name is secure.bin. When booting with the main and
backup application files fails, the system boots using the secure application file. If booting with
the secure application file fails, the system prompts a boot failure.
Note that:
