File transfer for configurations and images: TFTP to SFTP

Back up a router's configuration to a server with TFTP, FTP and SCP, try SFTP from the server, compare what each protocol protects, copy a file into flash and verify its hash before an upgrade, and turn another router into an SCP server.

Run this lab

It needs Lite: its 4 nodes are set to 4 vCPU and 4,096 MB in total. That fits the free demo too.

The scenario

Brackenfield College has no configuration backups and a router upgrade coming up. Its new file server (SRV, Ubuntu) offers every common transfer protocol. You'll back up R1's configuration with each one, see what each protects, stage a file in flash and check its hash the way you would before an image upgrade, and finally let the team pull files from R2 over SCP.

DeviceAddressNotes
R110.29.0.1/24router to back up
R210.29.0.2/24will become an SCP server
SRV10.29.0.100/24TFTP root /srv/tftp; FTP user ftpuser / FtpPass2026; SSH, SCP and SFTP user netbackup / Backup2026

What you’ll practise

  • Compare TFTP, FTP, SCP and SFTP: transport, ports, authentication and encryption
  • Explore IOS file systems and back up the running configuration with each protocol
  • Copy a file into flash with SCP and verify it with an MD5 hash
  • Enable the IOS SCP server and understand what it needs
  • Describe the IOS image upgrade procedure

The tasks

  1. Compare the protocols
  2. Explore the router's file systems
  3. Back up with TFTP and FTP
  4. Back up with SCP and SFTP
  5. Stage a file and verify its hash
  6. Make R2 an SCP server

The Lab Tasks pane has the scenario, these tasks, the checks to run, hints and the full solution.

How to open this lab

  1. Sign in to your workspace at lab.cloudlabbox.com.

  2. In File Manager, open Shared, then the folder CCNA 200-301 guided labs.

  3. Open 29 - File transfer for configurations and images - TFTP to SFTP and start its nodes, then open Lab Tasks for the scenario and the steps.

The lab is read-only. You can start the nodes and configure the devices, but changes to the topology can’t be saved. To change it, rebuild it in your own folder.
