Zorluk: OrtaTFTP and FTP Operations for System Images and Configuration Management

A network administrator needs to back up a Cisco IOS router's running configuration to a remote FTP server that requires user authentication. Arrange the Cisco IOS CLI operational and configuration steps in the correct chronological sequence to perform this transfer.

  1. 1Configure the global FTP username and password using the 'ip ftp username' and 'ip ftp password' commands.
  2. 2Verify Layer 3 reachability to the remote FTP server using the 'ping' command.
  3. 3Execute the 'copy running-config ftp:' command from privileged EXEC mode.
  4. 4Specify the remote host IP address and destination file path when prompted by the CLI.
  5. 5Verify the successful transfer status and byte count output displayed in the terminal.

Cevap

The correct operational sequence begins with defining global FTP credentials ('ip ftp username' / 'ip ftp password'), testing reachability via 'ping', issuing 'copy running-config ftp:', supplying the destination address and file details at the CLI prompts, and finally verifying the completed transfer output.
FTP file management in Cisco IOS relies on control connection authentication and valid network routing. Pre-defining FTP credentials via global configuration ensures seamless connection establishment. Verifying IP reachability with ping confirms path availability before starting data transfer. The interactive 'copy running-config ftp:' command guides the user through target address and filename parameters, culminating in confirmation of the completed transfer.

Adım Adım Çözüm

1
Set the global FTP authentication credentials in global configuration mode.
The IOS device is pre-configured to automatically supply credentials when opening FTP control connections.
FTP requires authentication; configuring 'ip ftp username' and 'ip ftp password' prevents connection drops during transfer.
2
Perform a ping to the FTP server IP address.
ICMP reply confirms Layer 3 IP routing and connectivity to the remote server.
Attempting a file transfer without basic connectivity verification leads to timeout failures.
3
Issue the copy running-config ftp: command in privileged EXEC mode.
Cisco IOS starts the interactive copy wizard for FTP.
This command specifies the running configuration as the source data stream.
4
Provide the remote IP address, destination filename, and confirm prompts.
IOS opens TCP port 21 control connection to the FTP server and streams the file over TCP port 20.
Interactive prompts ensure the file is routed to the exact server path designated by the administrator.
5
Examine the CLI summary output indicating bytes copied and elapsed time.
Confirmation that the configuration file was written cleanly to the remote storage directory.
Verifying transfer statistics ensures early detection of incomplete or corrupted transfers.

Anahtar Kavram

FTP requires pre-configuration of authentication credentials or URL-formatted inline credentials in Cisco IOS prior to initiating copy operations.
