The Switches provide very convenient function for configuration backup/recovery. No TFTP server is needed. While accessed into the web management interface, if you need to backup the current configuration, you can move to the System/Backup & Recovering menu web page. Click on the Backup the system's parameters link, the function would bring up an application window on your workstation to figure out the location where to save the configuration file.
The configuration recovery function also guides you to restore the configuration from your workstation.
