Configuration Files - H3C SR6608 Installation Manual

H3C SR6608/6604 Routers Installation Manual
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 section 7.6 "Maintaining Application and Configuration Files" on page
7-34.
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:
An application file with the attribute of M, B, or S can be used to boot the system,
but one with an attribute denoted by N/A (that is, an application file without a
specific attribute assigned to it) cannot.
You can modify the attribute of application files using the BootWare menu or the
command line interface (CLI) after the application is started.
As the secure application file is the last resort for system boot, you cannot change
its attribute, or turn another type of application file into a secure application file by
means of attribute modification. You can only download it using the BootWare
menu.
Only one file of the same type (M, B, or S) can exist in the CF card. For instance, if
a file in the CF card has both M and B attributes, no other file with the attribute of M
or B can exist in the CF card. If the attribute of another file is changed from N/A to
B, the existing file that has both M and B attributes will lose its B attribute.

7.1.4 Configuration Files

The configuration files are used to store the configuration information of the router and
load the configuration information at system boot:
1) A system that supports the main and backup attributes of configuration files
defines three types of configuration files by default:
Main configuration file (with the attribute of M)
Backup configuration file (with the attribute of B)
Default configuration file (with the attribute of S)
The main and backup configuration files are used as follows:
