Save Cisco IOS Configuration using Putty

1. Launch putty and connect to your Cisco router or switch

2. Enter the user exec mode

 

router> enable

or

router> en

 

If password protected, enter password.

 

Password: 

3. Enter the terminal length 0 command

 

router# terminal length 0

 

This will return the entire response at once instead of one screen at a time without the –more– prompts requiring you to hit enter over and over again.

 

4. Right-click on the menu bar at the top of the Putty screen and select “Change Settings”

 

5. Go to Session and click on Logging, select “Log all session output”

 

6. Click on Browse and choose the location and the name of the file  and click apply.

 

8. Now enter the show run command

 

router# show run

 

Confirm that the output was saved and that config.txt file is indeed the correct configuration.
