*** CAUTION ***
This command is used to download a backed-up configuration
for a specific switch. If using a file from a different
switch, this file‘s configuration settings will override
any current switch settings. Downloading a configuration
file, which was uploaded from a different type of switch,
may cause this switch to fail. A switch reboot might be
required for some parameter changes to take effect.
configDownload operation may take several minutes
to complete for large files.
