A configuration file must use .cfg as its extension name and the startup configuration file must be saved
in the root directory of the storage medium of the AP.
Backing Up the Startup Configuration File
Follow the step below to back up the startup configuration file to be used at the next system startup:
To do… Use the command… Remarks
Back up the configuration file to be
used at the next system startup to
the specified TFTP server
backup startup-configuration to
dest-addr [ dest-filename ]
Required
Available in user view
Before backing up the configuration file:
z Make sure that the server is reachable, the server is enabled with TFTP service, and the client has
permission to read and write.
z Use the display startup command (in user view) to view whether you have set the startup
configuration file, and use the dir command to view whether this file exists. If the file is set as NULL
or does not exist, the backup operation fails.
Deleting the Startup Configuration File to Be Used at the Next Startup
You can delete the startup configuration file to be used at the next system startup at the CLI. On a
device that has the main and backup startup configuration files, you can choose to delete either the
main or backup startup configuration file. However, in the case that the main and backup startup
configuration files are the same, if you perform the delete operation for once, the system does not
delete the configuration file but only sets the corresponding startup configuration file (main or backup,
according to which one you specified in the command) to NULL.
You may need to delete the startup configuration file to be used at the next startup for one of these
reasons:
z After you upgrade system software, the existing configuration file does not match the new system
software.
z The configuration file is corrupted (often caused by loading a wrong configuration file).
When the startup configuration file is deleted, the device uses the null configuration when it reboots.
