Network Automation isn't difficult. With just a few CLI commands you can automate the backup of your Cisco networks. Use Kron and archive to back up configs to TFTP, FTP or SCP servers. Don't try to do everything manually. Automate it! Just like cron in Linux, you can use kron on Cisco IOS to schedule things. Schedule backups, schedule TCL scripts and much more.

Amaze others with your knowledge of the Cisco IOS. You don't need python for these scripts. Rock that job interview and show senior network engineers what you can do. Keep on learning and change your life. Get that good paying job by showing your skills.

1) Intro: 0:01

2) IOS requirements: 2:02

3) Lab Setup: 2:42

4) Kron config: 4:24

5) Archive config: 9:01

In later videos I'll show you how to use Python scripts and other cool options on Cisco IOS devices.
