He is currently finishing up his CCVP. He is also focused on mobile technology his company has published over apps forthe iPhone.
He has been a Cisco instructor for 12 years, start-ing with basic courses and now teaching Unified Computing, Nexus switching and otherdata center technology. John lives in Florida with his wife and three kids. This book is dedicated to you. Yesthe person reading this right now. No, Im not beingcheesy, Im serious! The only real way people are truly successful and fulfilled in thiscareer is to love what theyre doing. Because of that, I put much effort within grammati-cal boundaries into not just communicating technical mumbo jumbohey!
MicrosoftWord didnt correct that! Who knew mumbo jumbo was a real word? I hope this book sparks something in you that blooms into aninteresting, fun, and fulfilling career. In case youre curious, dictionary. It also says that mumbo jumbo is a masked man who combats evil in the westernSudan. I dont think either of these was my intention. This book is dedicated to my wife Liana, without whose unflinching support, it mightnever have happened.
You and me, love. AcknowledgmentsJeremy D. Cioara: When you go see a movie, ever notice how the credits roll for about5 minutes with hundreds of names? Its the same with this book. There are probably hun-dreds of names youll never see that had some part in making this book possible. Mythanks goes to all of them! Personally, I give thanks to Jesus Christ who iswell, everything! Without Christ, myworld of color quickly fades to a dull, boring grey. Thanks to my wife, who tirelesslyhomeschools our three kiddos and puts up with my countless Matrix analogies to explainanything under the sun.

The use of the word partner does not imply a partnership relationship between Cisco and any other company. He has been teaching networking classes full-time since January and part-time for three semesters prior to that.
Brent previously worked as a network specialist at the Madison Metropolitan School District, where he managed a network of over 50 schools. Brent has been a regular presenter at the Cisco Academy conferences.
About the Contributing Authors David Bateman is a Certified Cisco Systems instructor with more than 20 years of internetworking experience. David has always enjoyed sharing his knowledge and has been a Cisco instructor for Skyline-ATS since His years of real-world technical and business knowledge allow him to bring a unique perspective to the classroom, where he not only delivers critical technical knowledge but can also explain how technologies can be used to address various business needs.
With over 20 years in the networking industry, he has performed in a number of roles, including network consultant, Certified Cisco Systems Instructor, and engineering director for a telecommunications company.
His accessible, humorous and effective teaching style has demystified Cisco for hundreds of students since he began teaching in He has devel- oped courseware and lab guides both for Cisco Systems and third-party clients. Mike has authored, co-authored, and technically reviewed several Cisco Press titles. He currently works as a Senior Network Engineer based on the East coast. Thankfully for me, this is not the Academy Awards, where the orchestra can cut me off if I go on too long.
I owe her thanks for her willingness to work with a first-time author to produce a lab book for the CCNA Voice certification. I owe her even more thanks for not sending the Cisco Press Ninja Assassins after me when I was late on my deadlines, even though I completely deserved it. Ellie and Mandie had the unfortunate task of working with a first-time author, trying to get me to complete everything and in a readable format. John not only had to correct my writing, but also to translate it into proper English.
To David Bateman and Brian Morgan. Their writing both helped to make this book more complete and kept the deadlines from slip- ping any further. To Brion Washington and Michael Valentine. As technical reviewers, they both made sure that I was as accurate as possible in explanations, and more than once caught areas where I made mistakes. As my dean and department head, respectively, they have made it possible to teach in one of the finest two-year schools in the state of Wisconsin, if not the nation.
They have made sure that my students have access to the equipment and resources in the class- room to succeed in their future jobs. To Cheryl Halle and Curt Chambers. As any instructor will tell you, his or her success is in large part due to the people who provide help, and Cheryl and Curt are the best at running our labs. The labs are so well run that the Cisco Academy has held instructor training qualifications here twice in the past year, and the Academy told us it could not have had an easier time.
There are many students who were guinea pigs for my labs over the past year and worked on my beta versions and many alpha versions. They had to put up with my hands waving in the air as I explained how cool this stuff was, even the QoS portion. However, there are two students who went above and beyond and deserve special recognition: Krzysztof Petrynko and John Endries.
They both put in numerous hours checking my labs and giving me valuable feedback. In addition to dedicating the book to my wife Megan, I also have to thank her for not only keeping things running at home I promise to start cooking dinner more often now that this is done!
She was the one to point out that I needed to hyphenate ever-patient in the dedication. There are few companies in the world that would spend millions of dollars to develop and maintain excellent cur- riculums and then give it to schools at no cost. My former students would not have their great jobs without the fantastic CCNA Exploration curriculum that the Academy offers.
I have found great suc- cess in teaching the Academy curriculum and learned many new things along the way. In actual con- figuration examples and output not general command syntax , boldface indicates commands that are manually input by the user such as a show command. Some of the labs or items in a lab in this book are marked as optional. In other cases, some labs can be completed and require optional hardware to test, but the key concepts can be learned without the hardware.
The goal of this lab book is to help students learn by doing. To that end, these labs contain far more than just step-by-step instructions to complete a task. The ideal scenario is that students understand why they are completing each step. When I first started writing labs, they were just simple lists of the commands to complete a task.
My labs grew longer as I added more descriptions and details. Every time I had more than a few students get stuck or encounter a problem in one place, I would add information on how to avoid the problem or how to troubleshoot the issue in the lab.
The result is the labs in this book. I found that most students love the detail I have put into the labs, and when they encounter a problem, the solution is often found nearby. However, I still have students in my class- room that just want to rush through a lab and skim it to find the commands that are printed in bold. Usually, by the fifth lab, they start to realize that I have commands that only apply in some circum- stances, and the commands will not work in other cases.
They learn to read the lab and carefully go through it. After a student understands the process, he does not get stuck as easily and is instead able to figure out what to do to solve a problem. When proceeding through the labs, it is advisable to save device configurations or back up servers in the case of CUCM at the end of each lab. Having access to this software is important to understanding the top- ics for the certification exam.
If you do not have access to the Cisco Unified Communications applica- tions, study the figures included with the labs, as figures for the most common or difficult items to configure were included in the labs. Alternatively, check with your local Cisco Networking Academy, as it has the ability to offer classes using the Cisco Unified Communications applications at academic pricing. Hardware and Software Used in the Labs This is a list of equipment used to develop the labs. Use the following equipment to ensure the best compatibility.
In a later section, alternatives will be explored. Some labs require two of these: one router for the HQ location and one for the branch office. The Cisco is specifically demonstrated. See Appendix C for more details. The speed of the processor s on this machine is the biggest factor in how fast the virtual machines will perform. Alternative Hardware Resources While the labs were created using the previously listed equipment, in many cases, other equipment will be adequate.
It controls all the functions of the phone calls. Additionally, the routers will be needed for the gateways in some of the CUCM labs. CUCM version 8.
