Hello,
I found an interesting feature on Cisco’s website. Here is a nice way to facilitate all network admins and networkers life ! 
EEM is a flexible system designed to customize IOS. It allows you to automate tasks, perform minor enhancements and create workarounds. You develop and run scripts in your own environment, program your own custom actions using Tcl and share your scripts with others by uploading them here. Download examples and useful scripts submitted by others for customization and use in your environment
