1.1 File Attribute Configuration
1.1.1 Introduction to File Attributes
An app file is an executable file, with .bin as the extension. A configuration file is used to
store and restore configuration, with .cfg as the extension. A Web file is used for
Web-based network management, with .web as the extension.
The app file, configuration file, and Web file have three kinds of attributes: main, backup
and none, as described in Table 1-1.

Descriptions on file attributes
Attribute
name
Description Feature Identifier
main
Identifies main startup files.
The main startup file is used
first for a switch to start up.
In the Flash memory, there
can be only one app file,
one configuration file and
one Web file with the main
attribute.
(*)
backup
Identifies backup startup
files. The backup startup file
is used after a switch fails to
start up using the main
startup file.
In the Flash memory, there
can be only one app file,
one configuration file and
one Web file with the
backup attribute.
(b)
none
Identifies files that are
neither of main attribute nor
backup attribute.
— None
Note:
A file can have both the main and backup attributes. Files of this kind are labeled *b.
If a newly created file is configured to be with the main attribute, the existing file with the
main attribute in the Flash memory will be changed to other attribute. This ensures that
there can be only one app file, one configuration file and one Web file with the main
attribute in the Flash memory. This circumstance also applies to the file with the backup
attribute in the Flash memory.
File operations and file attribute operations are independent. For example, if you delete
a file with the main attribute from the Flash memory, the other files in the flash memory
