A guide to building and modifying Tcl scripts to automate network administration tasks

 

Streamline Cisco network administration and save time with Tcl scripting

 

Cisco networking professionals are under relentless pressure to accomplish more, faster, and with fewer resources. The best way to meet this challenge is to automate mundane or repetitive tasks wherever possible. In this book, three Cisco experts show you how to use Tcl scripting for Cisco IOS devices to do just that.

 

You’ll learn easy techniques for creating, using, and modifying Tcl scripts that run directly on Cisco network devices from the Cisco IOS command line. The authors first teach basic Tcl commands and concepts for capturing and manipulating data and for querying or controlling Cisco equipment. Building on these core skills, they show you how to write scripts that automate and streamline many common IOS configuration, monitoring, and problem-solving tasks.

 

The authors walk through the entire script development process, including planning and flowcharting what you want to accomplish, formatting your code, adding comments, and troubleshooting script errors. They also present many downloadable sample scripts, along with practical guidance for adapting them to your own environment.

 

Whatever your role in managing, monitoring, or securing Cisco IOS networks and equipment, this book will help you get the job done more rapidly and efficiently.

  • Automate routine administration tasks you’ve always performed manually
  • Instantly collect and modify IOS router configurations and other data
  • Write Syslog scripts to document failures, monitor network health, collect statistics, and send alarm messages
  • Implement automated network performance measurement using IP SLA
  • Use the Embedded Event Manager’s event detectors, server, and policies to customize device operation
  • Trigger preplanned actions to correct problems as they arise
  • Simplify policy management using the Tcl script refresh feature
  • Protect Tcl script security with digital signatures and PKI
  • Understand how Tcl functions within the Cisco IOS environment
  • Master Tcl syntax and commands through hands-on practice
  • Learn best scripting practices through expert examples
  • Quickly modify this book’s examples for your own environment

This book is part of the Networking Technology Series from Cisco Press®, which offers networking professionals valuable information for constructing efficient networks, understanding new technologies, and building successful careers.

This book is not an easy read cover to cover but it's a great resource for the network engineer who, like me, also enjoys programming. There are tips and samples that can be converted into cool time saving programs

5.0 de un máximo de 5 estrellas TCL Scripting for Cisco IOS 20 de junio de 2010
Por S. Pollock - Publicado en Amazon.com
Formato: Tapa blanda
Though it's been a few years, I was originally a programmer by trade before becoming a network engineer so I was excited to get my hands on Ray and Team's latest book on scripting in TCL for Cisco IOS.

I was not disappointed. This is the definitive book on harnessing the power of EEM and TCL for managing a network and is a "must have" reference for every administrators bookshelf.

I was not fluent in TCL when I began and the chapter on the basics gave me exactly what I needed to know to get started including where to get the distribution (if you don't happen to have access to an IOS router to practice on). , TCL is available on the [...] site, a great place to get other (free) scripting languages as well, Perl being one of my favorites at the moment.

After you learn the basics of TCL and then how to access the IOS command set, they take you on a tour of Embedded Event Manager (EEM) and I must say this has to be one of the best descriptions of EEM functionality I have run across. Then things get serious, this book takes you through some very detailed advanced operations including embedded syslog manager (ESM), embedded menu manager (EMM) and IPS service Level Agreement (IPSLA) measurements as well as SNMP proxy and Remote Procedure Calls.

A complete work, this book is thorough and the examples are relevant. You get a step by step guide on how to write an application from start to finish. The scripts provided are a testament to Ray's attention to detail and I was quite impressed with his vast knowledge of the subject matter. Not only does he provide insight into the use of TCL and IOS but also how to present the output using HTML, javascript, and even a touch of flash for charting.

Leaving no stone unturned, this team provides a very complete study of the security issues surrounding a real world implementation including how to go about signing your TCL scripts using PKI and a very complete, step by step, example is included.

It's getting more rare these days that I get a chance to review technical books and I must say, this one was a real pleasure. I would recommend for anyone that is actively managing networks today.

5.0 de un máximo de 5 estrellas A Good Introduction 22 de marzo de 2011
Por John Matlock - Publicado en Amazon.com
Formato: Tapa blanda
The first thing that I'd say about this book is to second the authors recommendation that you start this whole Tcl project by downloading the Tcl interpreter from tcl.tk onto your PC and practice with it there. They have versions for Windows, Apple and several flavors of Unix. To quote the authors of this book: "This is probably a better place to start, rather than practicing on production equipment, especially if you want to keep your job."

If you are not familiar with it, Tcl (usually pronounced tickle) is a full fledged programming language. It's usually interpreted so that it runs a bit slower than other languages but is much faster to develop programs since you eliminate the compile step. If you've programmed in any language, the introduction in Chapter 2 is probably enough to get you started. There is also a lot of programming information on the tcl.tk web site and several books on the language.

The rest of this book is an introduction to the particular features that Cisco has implemented in their IOS and the way that tcl interfaces to it. It is an introductory book, aimed at getting you started. You could get everything in this book from the tcl web sites and Cisco documentation. But here the material is clearly and neatly organized, all in one place and the writing won't put you to sleep nearly as fast as will the official documentation.

Don't get too excited!

The title "TCL Scripting for Cisco IOS" might make you think you'll be able
to drill the guts out of your router and utilise IOS functions unknown to
most, but that's not the case. This is quite an elementary reference.

Authors take a step by step approach, providing a reference to the TCL
language from chapter 1 through chapter 2. It is quite detailed, and can be
used by a novice programmer to learn the insight of TCL.

In chapter 3, TCL interaction with IOS is addressed, explaining the function
of `tclsh' command interpreter and how it can be used in conjunction with
SNMP.

Chapters 4 through 5 cover the Embedded Event Manager (EEM),
Embedded Syslog Manager (ESM) and Embedded Menu Manager (EMM).
They are well written and provide fine and thorough explanation of the
advanced capabilities they expose to the network administrator. The
examples give a glimpse of what can be achieved in a network's daily
operation.

In chapter 6 the creation of a TCL application is covered. Authors explain in
extreme detail all required steps that a programmer should take in order to
develop an application. There is so much information that it sometimes
becomes cumbersome for an advanced programmer to read.

The last chapter covers the issues of security in TCL scripting. Detailed
steps about script signing and distribution present an excellent guide.

As a final comment, this book is a good starting point for a novice
programmer that needs to interact with a Cisco device but it can easily be
replaced by Cisco's documentation on EEM and a TCL language guide.

It could be enhanced by including information about Cisco TCL libraries
and Cisco Voice which makes extensive use of TCL.

There are also quite a few typos and formatting issues that need to be
addressed in this edition.
