TcL Scripting for Cisco IOS

Network professionals are under relentless pressure to accomplish more, and do it faster, with fewer resources. The best way to meet this challenge is to automate mundane or repetitive tasks wherever possible. This book shows how to use the Tcl scripting language to do just that. Three Cisco experts demonstrate how to create simple Tcl scripts that automate and streamline a wide variety of tasks involving IOS router configuration, monitoring, and problem-solving: scripts that can potentially save network administrators many hours per week. You begin by mastering basic commands and concepts needed to write any Tcl script that captures and manipulates data. Once you've mastered these foundational Tcl skills, the authors demonstrate how to write Tcl scripts that query or control equipment in the Cisco IOS environment. Along the way, they present a wide range of downloadable sample scripts designed specifically for IOS, together with practical, detailed guidance for adapting these scripts to any Cisco network environment.
