Table 323 Descriptions on file attributes
Attribute name
none
n
A file can have both the main and backup attributes. Files of this kind are labeled
*b.
Note that, there can be only one app file, one configuration file and one Web file
with the main attribute in the Flash memory. 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 lose its main attribute. 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 will not possess the main attribute. If you download a valid file with
the same name as the deleted file to the flash memory, the file will possess the
main attribute.
After the Boot ROM of a switch is upgraded, the original default app file has the
main attribute.
Configuring File You can configure and view the main attribute or backup attribute of the startup
Attributes file used for the next startup of a switch, and change the main or backup attribute
of the file.
Perform the configuration listed in Table 324 in user view. The display commands
can be executed in any view.
