1.1 File Attribute Configuration

1.1.1 Introduction to File Attributes

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:
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.
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 and the same type 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. It is the same with the files in the Flash that are of the backup
attribute.
Description
The main attribute identifies
main startup files. The main
startup file is used first for a
switch to startup.
The backup attribute
identifies backup startup
files. The backup startup file
is used after a switch fails to
startup using the
startup file.
Files that are neither of
main attribute nor backup
attribute are of
attribute.
