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.
An app file, a configuration file, or a Web file can be of one of these three attributes:
main, backup and none, as described in Table 1-1.
Table 1-1 Descriptions on file attributes
Attribute
name
main
backup
none
Note:
A file can have both the main and backup attributes. Files of this kind are labeled as *b.
If a newly created file is configured to be of the main attribute, the existing file in the
Flash that is of the same attribute loses its 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. It is the same with the files in the Flash memory that are of the backup
attribute.
Configuration
Description
Identifies main startup files.
The main startup file is used
first for a switch to startup.
Identifies backup
files. The backup startup file
is used after a switch fails to
startup using the
startup file.
Identifies files that
neither of main attribute nor
backup attribute are of none
attribute.
