2110 CHAPTER 115: FTP C ONFIGURATIONc CAUTION: Startup files for next startup must be saved under the root directory.For the details of this command, refer to “Device Management” on page 2005.Configuring the FTPServerConfiguring FTP ServerOperating ParametersThe FTP server uses two modes to update files when you upload files (use the putcommand) to the FTP server:■ In fast mode, the FTP server starts writing data to the Cf after file transfercompletes. This protects the files intended to be overwritten on the device frombeing corrupted in the event that anomalies, power failure for example, occurduring a file transfer.■ In normal mode, the FTP server writes data to the Cf during file transfer. Thismeans that any anomaly, power failure for example, during file transfer mightresult in file corruption on the router. This mode, however, consumes lessmemory space than the fast mode.Follow these steps to configure the FTP server:ConfiguringAuthentication andAuthorization forAccessing FTP ServerTo allow an FTP user to access certain directories on the FTP server, you need tocreate an account for the user, authorizing access to the directories andassociating the username and password with the account.Follow these steps to configure authentication and authorization for FTP server:To do...
