Read an Excerpt

Chapter 1: Bridging/Switching

This first chapter will introduce you to VLANs and how to configure VLANs on Cisco switches using static VLAN number assignments. Understanding frame tagging within a VLAN will also be discussed.

When there is more than one path through the network, data can come back to the original source. In this situation, Spanning-Tree Protocol (STP) is used in Layer 2 switched networks to prevent these network loops, and to block ports that can allow data to return, causing a loop. We will discuss the basics of STP and how to use STP in a Layer 2 switched internetwork.

Cisco switches can operate in three different LAN switch modes: store-and-forward, cut-through, and FragmentFree. This chapter will discuss all three methods.

The chapter will end with a discussion of the Point-to-Point Protocol (PPP). PPP is used to connect either asynchronous serial or synchronous serial links. Configuration of PPP, as well as PPP authentication, will be discussed.

Switches were placed in networks to replace bridges and hubs in flattopology networks (where there is no segmentation of broadcast or collision domains). As networks grow, so does the amount of broadcast traffic. Not all broadcasts are bad; they are a necessity in today's networking protocols, to allow the location of certain devices to be known throughout the network segment. But when devices on the same network segment number in the hundreds, the result of all these devices sending broadcasts as well as data traffic can slow the network and the devices to a crawl.

Excessive broadcasts reduce the bandwidth available to end users and require every node on the network to process every frame,regardless of whether it is the intended recipient of the data. The processor in each machine is responsible for doing this task, taking away from the processing power needed for the end-user applications.

As more and more broadcasts enter your network, the network can actually grind to a halt. This situation is known as a broadcast storm. Broadcast storms occur when broadcasts throughout the LAN use up all available bandwidth, bringing the network completely to a stop. Switches use VLANs to segment the network into smaller broadcast and collision domains. Let's look at the two different types of VLANs, both static and dynamic.

NOTE Token Ring, Fast Ethernet, Gigabit Ethernet, and Fiber Distributed Data Interface (FDDI) are also interfaces that can be found on Cisco switches.

Static VLANs

If you want to allow different ports on a switch to be part of different subnetworks, you need to create virtual LANs within the switch. A virtual local area network (VLAN) is a logical grouping of network users and resources connected to defined ports on the switch. A VLAN looks like, and is treated like, its own subnet. By using virtual LANs, you're no longer confined to physical locations. VLANs can be created by location, function, department-even by the application or protocol used-regardless of where the resources or users are located.

VLANs are created by an administrator to break up broadcast domains in a Layer 2 switch. The administrator then assigns switch ports to the VLAN. This objective will discuss how VLAN assignments are created and configured on Cisco switches.

Critical Information

The two types of VLAN assignments are static and dynamic. A static VLAN is the typical means of creating a VLAN. The switch port to which you assign a VLAN association maintains that association until an administrator changes the port assignment. This type of VLAN configuration is easy to set up and monitor, working well in a network where the movement of users within the network is controlled. Using network management software to configure the ports can be helpful but is not mandatory.

Dynamic VLANs determine a node's VLAN assignment automatically. Using intelligent management software, you can enable hardware (MAC) addresses, protocols, or even applications to create dynamic VLANs. For example, suppose MAC addresses have been entered into a centralized VLAN management application. If a node is then attached to an unassigned switch port, the VLAN management database can look up the hardware address and assign and configure the switch port to the correct VLAN. This can make management and configuration easier for the administrator. If a user moves, the switch will automatically assign them to the correct VLAN. However, more administration is needed initially to set up the database.

Cisco administrators can use the VLAN Management Policy Server (VMPS) service to set up a database of MAC addresses that can be used for dynamic addressing of VLANs. VMPS is a MAC address-toVLAN mapping database.

Necessary Procedures

To configure VLANs on a switched internetwork, you need to follow the steps listed below:

  • Configure the VLANs.
  • Assign switch ports to VLANs.

It is an okay book to start studying for CCNA with but not the complete bible. It was a bit of disappointment for me. 1. The writer is not methodical, he skips steps. I found asking myself 'how the hell did he get here?' many many times. 2. The software CD the book came with is a blunder. It is a crappiest piece of software. Several commands shown in the book do not work on any of the routers/switches (for ex:int s0/0 did not work on any switch, yet the book mentions it a lot). 3. The writer is poorly organized. 4. Several sections in the book can be well understood if more figures, charts, maps, were included. 5. The publishers have done a terrible job too. If a figure is being referenced frequently, it should be located on the same page or opposing page as the references. I kept flipping pages back and forth to read and look at the figure. This is my pet-peeve about this book.

Follows the objectives pretty closely. Passed the exam on the 2nd attempt. The exam is very hard, but this book covers all the basics that you need to know. Add hands-on or routersim.

I read all the way through this book twice before taking the exam, and it specifically says several technologies (for example RIPv2, & NAT, just to name a couple) would not be covered. I showed up on test day and - you guessed it - I had several questions each on these two and other technologies that I chose not to study! I failed the exam by one question, and had to buy the Cisco Press book. A much much better book.

When I started for my CCNA I knew almost nothing about the material. I used this book in conjunction with the Cisco ICND book (Interconnecting Cisco Networking Devices) and got a passing score of 860. Lammle's book was very easy to learn from, and the simulator and practice tests were fairly good. I found his WAN chapter difficult to learn, so I used the WAN chapter in the ICND book. I didn't feel that his practice tests on the CD were very close to the actual exam, so I'd look elsewhere for practice tests if you feel you need more practice.

I passed the CCNA with 1000 out of 1000. This book does an excellent job of clearly explaining the exam essentials. The practice exams in the book are similar to the actual test questions. Flashcards for the PC are very beneficial too.

If you want to learn IP routing, this book will not take you anywhere close. For that you would need 'Cisco IOS for IP Routing' by Andrew Colton or Doyle's books. However, Lammle's book would probably be all you need to pass the CCNA test. Unless you're a complete beginner, then you may want to add one or two other fine CCNA books.

This book helped me pass the CCNA. It is written for novice users and above and is easy to read. It is direct and down to the point. Plus the testing software that comes with the book is excellent. I would never have been able to pass the CCNA if it weren't for this book. :)

This book has every thing needed to pass the exam. The labs are very nice. If you really want to knock the exam out, add the CCNA Router Simm and you will pass easily. I passed with a 949, first shot.

This book allowed me to pass my CCNA exam with a 903 on the first try. Only 3 weeks of studying and reading the book twice. This book explains all of the neccessary information to learn what it takes to be a CCNA. If you are a perfectionist, though, and want to score 1000, I recommend also reading the Cisco Press book for the extra technical details.

This book does an outstanding all around job explaining the subject matter in plain english. It did miss a few points though, such as supernetting and a better explaination of multicasting. It could also have provided little more info on WAN protocols.

I passed the exam with 947 after using this and the official book. This book is not as detailed as the Cisco Press one, but very easy to read. This book should be used 4 the basics n the other one's CD for the exam

Hi! I have given my exam on 13 September 01. Passed my Cisco CCNA exam on my first try with a score of 956. Thanks Todd for writing this book and making CCNA possible to me. I will highly recommend this book. Todd has covered OSI reference model & layered communication, Network protocols, Routing, Network Management, LAN design, Cisco IOS very well. The only weakness in this book is he has to go in more detail on WAN protocol, Bridging & Switcxhing. Hope this will covered on next edition. There are good sample questions which are very similar with the exam. I realy enjoyed the lab session. Hasan Mahmood MCSE, CCNA ASKCCNA@msn.com

I just passed my CCNA 2.0 test with a score of 924. This book covers everything you need! Along with the virtual lab e-trainer, you will be unstoppable come exam time. Lammle's language is very easy to understand, and his concepts come across easily. A must read for someone looking to break into the Cisco router market!

I bought this book, hoping to revise the key points that I might have missed using the study guide. But as the exam came near I realized the best way to revise is to go through the study guide yourself and there is no subsitute to it. It highlights the main points but the test is more based on your overall ability. I passed my test with 849 so I would say its your call to buy this book or not

Well I work in a company as a networking intern. The only hands on experience I had was upgrading the IOS on switches. I bought this book along with the virtual e-trainer. Didn't study that hard and the last bit on WAN protocols I just read twice, but I passed the Exam with 849 at my first attempt. So I became the third and the youngest certified person in my dept. I would highly reccomend this book and only this book as it covers the topic with enough detail to pass the exam. Others book either over do the details or skip some vital information.

I heard this is one of the best books to use, when preparing for the CCNA. I've been taking Cisco classes for the past two years, but for the past two weeks, i've been preparing for the CCNA test, I take it in 6 days if i pass i'll let you know if the book is good or not.
Guest More than 1 year ago
Just passed CCNA 2.0 today for the first try with score 946! Ok, I graduated in MS. Computer Eng., but I didn't know what IOS is at that time. Just 2 months later I passed with that impressive score. Only read the book and do all the excercises and labs, you're ready to go!!!

This book is good, contains most material needed for your CCNA exam, is well organied and easy to understand, but be careful with the errors.
Guest More than 1 year ago
Read the book about 4 times from cover to cover and took the practice exams. This book is what you need for the 640--507 test.
Guest More than 1 year ago
The book covers all the relevant material as well as being very well written. The author is easy to understand and has examples for every IOS command. The questions at the end of each chapter are also excellent practice for the exam.
Guest More than 1 year ago
Contains about 90% of the CCNA test. This is the only book I use. But it has some errors in the book and attached CD. Overall, this is a easy reading and good book.
Guest More than 1 year ago
I was taking the CCNA program at my community college until I bought the book. It is written clear and easy to understand. All you really need is this book and the e-trainer and you have it down packed!! I hope the CCNP books by Lammle are as good.

I went to the Cisco Academy and was taught version 1.0 all the way through Level III. Then in Level IV we switched to version 2.0 and had to take the version 2 test. I would not have passed my CCNA without this book. It filled in the gaps between the two versions of the Cisco curriculum.
Guest More than 1 year ago
Thanks to Todd and Sybex I just passed the test. This is the only book I used, thought I have a year and half experience with Cisco routers but this still a good book to make you more understand the everything in 'Cisco way'.
Guest More than 1 year ago
I found this to be a very good introduction. A good place to start. If you have the Microsoft MCSE you will find some of the material a good review.
