I am going to mention two easy methods to backup router / switch configuration file.

• Using Putty logging
• Using TFTP

Using Putty Logging

1. Open router / switch terminal via putty connection.
2. Enter enable mode (by entering enable command).
3. Enter command terminal length 0 (to display show run commands without breaks)
4. Right click putty and select Change Settings.



5. Select Session
• Logging
• All Session output
• Log File Name – path and filename of the config file.



6. Enter command show run on your router/switch.
7. Close the session.

Using TFTP

1. You can transfer file from router/switch to your TFTP server.
2. For TFTP server, you can use open source TFTPD32 application.
• Download Link – http://tftpd32.jounin.net/tftpd32_download.html
3. Configure your TFTPd32 application as shown in screenshot.



• Current Directory – Directory where you want to store your configuration file.
4. Enter following command in enable mode of your router / switch.
• Copy running-config tftp:
• Enter the tftp server address – eg. 192.168.0.101
• Enter the file name of the config – eg. r1-config

Similary you can use this method for copying firewall or other device configurations.
