Comment/Feedback/Suggestion by a Volunteer of DNS 3.....

CCENT Bootcamp-

It's really a very much good program that done by respected lectures...We as a student from DNS 3 July 09F, Would like to take this opportunity to thank all of you who worked hard for this camp to make sure we pass the exam....

Unfortunately not most who was able to fulfill the promise, but we promise the next time will be a record.

It's a situation that cannot be blamed anyone, we should blame our self for our failures.

About this camp we can hope about 20 percent.....the other it's in our hand, So now we all are gonna go to gain an priceless knowledge of working experience...
So just use the free time of yours to just go through the given notes and VCE files.....And mastered those two Cisco Discoveries...

And i planned to retake the CCENT exam on our LI time, Expecting that the coming DN3 student's camp starts after April 29th.....and hope that we all can participate and complete our unfinished business and promise.....

I heard that the coming DNS will be sit for a exam and those who pass will the chosen to sot for the CCENT....i think you guys can understand how lucky we are given a chance....To sit for this Professional Certificate......

Those who still don't understand or know nothing about this professional certificate please wake up from your dream and ask someone who knows the value of it...even you can ask your DAD/MOM......So put your ego a side and start to explore about this....

*Please wake up now and start searching...guys this life is fulfill of treasures you who need to find it with clues that given......Don't regret after...The one who saying this not your age...i hope you guys understand what I'm trying to say....

TIPS:

+If can go for any book stores look for CCENT books - if you ask me you can find it at KINOKUNIYA KLCC Surya, i brought for RM3++.....
+Surf Online for CCENT questions and print out and try to do it by your self.
+Study back all the materials that given in CCNET Boot Camp-That 9tut folder and some more.
+Study back all those two CISCO DISCOVERY.

And by here i would like to wish Ahmad Musyeriey for the success.
Those who didn't achieve this time we will try again...Next time the unbreakable record is ours...

So god bless you and good luck for the practical training and thanks for the respected lectures to give us this priceless chance.

*We really will appreciate if the camp period increased to at least one week. And no slots at night, because that's the time for us to recall back all the learned stuff.

Thanks.

How to create your own Cat 5 patch cables

Networking cables are a dime a dozen. You can get them just about anywhere…in standard sizes. But what happens when you need an odd size or you simply follow the beat of a DIY drum? In those cases you will want to know just how to make your very own Cat 5 Ethernet cables. And whether you need straight-through or crossover cables, TechRepublic has you covered.

In this article I am going to show you how to create both straight-through and cross over network cables.

What you will need

• Cat 5 cable
• RJ 45 Crimping tool
• RJ 45 Connectors
• Wire cutters (Leatherman-like multi-tool is ideal because it also has a knife that you might need)
• Cable Tester

Preparing the cable

The very first thing you need to do is to cut the cable to length. Once you have the cable cut to length, you will want to remove enough of the outer casing on each end to expose the inner wires so you can work. You will want to remove about an inch of the casing at each end. To do this I like to use a knife and very lightly score the outer case and then bend the wire at the score so the casing breaks. The casing should then peel right off the wire.

After you peel the casing off, separate the individual wires. You might have to cut away any insulation that is surrounding or between the inner wires. Once you have the wires separated you will want to make sure those wires are as straight as possible to make alignment and insertion into the RJ 45 connector simple.

Aligning the wires

Now comes the part that usually trips new users up. You have to make sure the color-coded wires are in the right order. First I will show you the order for a straight-through cable. A straight-through cable is a standard Ethernet cable. If you take a look at Figure A you will see the order you should use for straight-through ends.

Figure A

Both ends should be color-coded exactly like you see here.

Now, let’s say you want to create a crossover cable. To do this you will create one end exactly as you see in Figure A and then the other end will be color-coded according to what you see in Figure B.

Figure B

Make sure your color-coding is exactly as you see above on ONE end for a cross over cable.

Attaching the connectors

This is another point of confusion. Pin 1 on the RJ 45 connectors is on the left side of the connector when the clip is on the bottom side. If you are looking at the connector from the top and the clip is on the top side then Pin 1 is on the right side of the connector.

The first thing you need to do is very carefully line the wires up, side by side, in the correct order and then, using the cutting blade on your crimping tool, cut the very ends of the wires off so the edges all line up. After you have that done, carefully slide the wires into the connector, paying close attention that they remain in the correct order.

Once the wires are pushed all the way into the connector slide the connector into the crimping tool (there is only one place the RJ 45 will go into the crimper - see Figure C) and crimp the connector. Take the connected end off and give it a tug to make sure the crimp took.

Figure C

A solid crimp will keep you from having a poor connection later on, but don’t crush the connector.

When one end is complete, repeat the process on the other end, paying attention to whether the cable is either a straight-through or crossover.

Testing the connection

Although you can always just plug the cable into its destination jacks to test, it is always better practice to use a cable tester to make sure the connections you just created work properly. This is always a must if you are creating a number of cables or you are creating cables that will then be deployed to a remote location. The directions for testing will be specific to the tester you own. Make sure, if you are testing a cross over, that you know exactly how to test for this cable before you assume everything to be good to go.

Final thoughts

Making your own Ethernet cables can, in the long run, save you money as well as allow you to make cables in non-standard sizes. And now, when you have the need, you can work your own personal magic on Cat 5 cable so you can have as many different patch cables as you need.

Some interesting twists about Ethernet cabling

Differential signaling

To understand why Ethernet cable is built the way it is, it requires familiarity with how the signals are transmitted over the wires. The fancy term is differential signaling. During a digital pulse, each wire in the pair carries a signal that is the same voltage, but opposite polarity. The slide below (courtesy of Wikipedia) exemplifies the process:

The greater the difference between the input pulses, the larger the output pulse, making it easier for the receiver logic to differentiate ones and zeros. I might add that this becomes more important as throughput rates increase.

As you can see in the slide, differential signaling has some noise-canceling capability, but not enough when it comes to Ethernet cabling. That’s because two types of interference come into play, electromagnetic radiation from sources such as power wires or crosstalk from other pairs in the same cable. Both introduce noise that reduces the differential. If there is enough noise, the receiver can misread what was sent.

It’s all about the twists

The Ethernet cabling most of us are familiar with consists of four pairs of wires, twisted together, and enclosed in a single insulating cover jacket. Those twists are a pain when making connections, but are there for a reason. Transmitting Ethernet signals over a cable that small would not be possible without them.

To understand the importance of twisting the wires requires learning about common-mode rejection. It seems that digital electronics connected with balanced lines, such as twisted pair Ethernet cabling are capable of rejecting noise, as long as the spurious emission is common to both leads in the twisted pair.

It might help to use an example. I mentioned crosstalk earlier. If pairs were not twisted in Ethernet cabling, it is entirely possible for two wires in adjacent pairs to be next to each other for the entire length of the cable. That could skew the results by adding cross talk to only one leg of the pairing.

If the wires in the pair were twisted, both wires in the pair would be affected the same. Then the receiver using common-mode rejection would be able to filter out the crosstalk interference.

Geek trivia alert: This phenomenon was discovered by Alexander Graham Bell. In fact, telegraph wires were the first twisted pair. The wires switched position on the pole after a certain distance (courtesy of Wikipedia):

Another twist

Ever notice that some of the twisted pairs are easier to un-ravel? There is a reason for that. If adjacent pairs have an equivalent twist rate or pitch, the same wires of each pair could be next to each other for the entire run, negating differential signaling. In order to prevent that, Ethernet cable manufacturers use different twist rates (courtesy of Wikipedia):

One last note, according to cabling best practices, pair wires should not be untwisted more than 13 mm. This comes into play when using punch-down blocks.

UTP versus STP

There are two types of Ethernet cabling, Unshielded Twisted Pair (UTP) and Shielded Twisted Pair (STP). Everything that I mentioned up until now, applies to both. STP cabling is used if there is an abnormal amount of electromagnetic interference. STP uses metal-foil shielding that directs any external noise to ground. The metal foil can surround each twisted pair (STP), all the twisted pairs S/UTP), or both (S/STP).

Some installation tips

Every time I work with cable installers, I bug them mercilessly, trying to learn what they consider important. Here are some of their pointers:

• For solid wire UTP, the minimum bend radius is eight times the outside diameter of the cable. Anything less affects the twist rate, reducing noise rejection.
• When installing long runs be careful not to stretch the cable, doing so could alter the twist rate, again reducing noise rejections.
• Due to the high frequency of digital transmissions, the phenomenon of skin effect comes into play. So be careful not to nick the copper wire.
• Make sure to use plenum-rated Ethernet cabling, if the run is located in a space that is used for air circulation.
• Run Ethernet cabling at least 15 cm from any high-voltage lines, 30 cm is better.
• If Ethernet cabling must cross a high-voltage line, do so at a 90 degree angle.

If I missed a tip you feel is important, please share it with the rest of us.

Final thoughts

As digital throughput rates keep increasing the margin for error decreases rapidly. Make sure to keep those pairs twisted.

Hate networking? Here are some tips

Devora Jack is the author of Networking for People Who Hate Networking.

Q: A lot of peoples consider themselves introverts, so networking for a job is really difficult for them. What are some of the “special techniques” you recommend for these people?

"My book is really filled with a myriad techniques designed for introverts to network in sync with their natural strengths, rather than fighting against who they are. This is validating, energizing, and infinitely more productive for the 50% of the population who identify as introverts.

Until now, introverts have been hit over the head with a single set of rules for “successful networking” - rules that directly contradict the introvert’s natural sensibilities. Seemingly, the only options are to behave falsely (an intolerable choice for an introvert) or to avoid networking altogether. Fortunately, now introverts can work with their strengths rather than assume they are doomed networkers.

The book offers techniques for numerous, typical networking situations - meetings and events, business travel, job searching, and so on. Here are a few samples:

Ask well-formed questions

Display a sincere interest in others. Inquiry into others’ interests and backgrounds is a tremendous networking skill. People love when others display an interest in them, and introverts don’t need to drum up ideas for typical, dull small talk. It is a brilliant networking strategy for introverts.

Do less

Prioritize your time, manage your energy. Shining bright at one event is smarter than straggling into every networking opportunity crossing your path. Grant yourself mini-recharge breaks at programs. Head outside for a breather, step away to refresh, decompress on a brisk walk, or check messages. Let go of what you should do; free yourself up to what appeals. You will be more appealing to others in the process.

Volunteer

Arrange in advance to help out. Many networking-haters are most comfortable when in a designated, structured role. Working the event provides you with a specific reason to engage with others, rather than poking around for small talk.

Get to events early

It is better to enter a room with a few people than one with a crowd packed close together. Gatherings are cozier near the beginning and participants more accessible.

Follow up

If you aren’t following up, you aren’t networking. The time you invest in networking is wasted without follow-up. Write a personal note within 48 hours, while you still remember each other. Be useful - include an article link, provide relevant information, or connect your new acquaintance with a valuable resource. Want to really stand out? Mail a handwritten note. Because introverts are frequently gifted writers, this is an opportunity to shine.

Network on your own terms

As a previous networking-hater myself, I know you can exceed your wildest networking expectations while having a great time in the process.

Q: You introduce a new term in your book–centrovert. What exactly is a centrovert?

Until now, we have been limited to two descriptors on the introvert-extrovert temperament continuum. This dichotomy neglects slight introverts and slight extroverts. Centroverts can relate nearly equally to both extremes of the spectrum. The term centrovert reminds us that personality types have infinite variations and few of us are on the extreme end. More specifically, it provides centroverts with a better understanding of their own strengths. Those in the middle can be made to think they are somehow weak or wishy-washy. Instead, they are in the best position to mediate, negotiate, and collaborate simply because they have an inherent understanding of different styles that is more challenging for the rest of us to develop."

What you need to know about Cisco's CCNA certification

Well, hello guys this is my another article that i have collected with resources, this is a continues part of my previous written article BOOT CAMP ,Eight ways to strengthen your Cisco networking skills...
I hope it will useful for us.

#1: What’s the value of a CCNA?

Before we discuss the value of the CCNA certification, let’s talk about the value of certifications in general.

The value of certifications programs is not in the “piece of paper” you receive — it’s in the knowledge you gain in the process. Unfortunately, not everyone who completes a program gains the same level of knowledge and skills.

In my opinion, here’s the value in pursuing CCNA certification:

• Prove your knowledge to yourself, and prove — and document — that knowledge to your boss or a hiring manager.
• Use your CCNA to stand out from others applying for the same job.
• Justify asking for a raise.
• Challenge yourself.
• Learn more about networking in general.

#2: Who should pursue CCNA certification?

In my opinion, anyone interested in networking should go for the CCNA. Obviously, anyone working with Cisco equipment on a daily basis is also a good candidate.

However, sometimes it isn’t that obvious. Here are a couple examples:

• Windows and Linux network administrators: Why not understand the network and learn how to solve problems more quickly? Learn to communicate with the “network guys.”
• IT managers: Learn how to better communicate with your network administrators, fill in for the network admin, and understand how the network works.

#3: How do I get a CCNA?

This is the easiest question of them all. To earn a CCNA, you have two paths to choose from:

• One test: You can just take test 640-802 — a single test that incorporates both parts of the ICND course material.
• Two tests: You can take tests 640-822 and 640-816. By passing test 640-822, you would earn the CCENT. Then by passing test 640-816, you would have both your CCENT and your CCNA certifications.

Note: Cisco exams 640-801 CCNA, 640-821 INTRO, and 640-811 ICND all expire on Nov. 6, 2007. While the study material for those tests is still very much applicable, you should watch out for topical differences that have changed.

#4: Can I pass the CCNA?

Absolutely. Before the recent introduction of the CCENT, the CCNA was Cisco’s introductory certification.

Next to Microsoft’s MCSE certification, the CCNA is the single most popular certification when it comes to available training material. There are router and switch simulators, test preparation applications, books, study guides, flash cards, training videos, Web sites, and more, available from both Cisco and third parties. The resources are immense! Sometimes the more difficult question is “where do I start?”

#5: What resources should I use to prepare for the CCNA?

People ask me this question all the time. Here’s my short list:

• Cisco’s CCNA Prep Center
• CCNA Self-Study Resources from Cisco Press (The best-known title is the CCENT/CCNA ICND1Official Exam Certification Guide by Wendell Odom.)
• Train Signal’s CCNA Training video series
• CBT Nuggets: Cisco CCNA Certification Package
• Cisco CCNA Routing Quiz
• TechRepublic’s 500+ resources for the CCNA keyword search

Summary

The CCNA is a valuable certification, but the level of value definitely depends on whom you ask. And, of course, certification is only as valuable as the experience it accompanies.

Weigh in with your opinion! What’s the value of the CCNA to you and to your company? What are the best resources available to prepare for the CCNA?

Eight ways to strengthen your Cisco networking skills

In the past couple of weeks, I’ve written a couple of articles about Cisco certification that generated a lot of response from DNS members. The most recent article, CCNA BOOT CAMP garnered a lot of excellent comments, many of which focused on gaining experience.

More than once, the old “chicken or the egg” conundrum came to mind as readers asked, “How do I get a Cisco job with no experience, and how do I get Cisco experience without a job?” TechRepublic member nacht probably said it best:

“What you have here is a chicken and egg problem: You can’t get the experience because you don’t have the certification, but the certification doesn’t help when you don’t have ‘enough’ experience.”

So how do you get the Cisco experience you need to get your foot in the door? Here are eight ways you can start strengthening your Cisco experience.

#1: Work for free

Two years ago, a friend of mine had no Cisco networking knowledge; today, he earns a significant salary as a network engineer. What happened? He got his experience by volunteering to work on Cisco equipment for free.

In his case, he volunteered at his church. Someone donated a Cisco VoIP Call Manager and phones, along with a bunch of Cisco switches, to the church. While working at the church in another area, he spent his spare time reading and researching the new Cisco equipment, learned how it worked, hooked it up, and managed to earn his CCNA certification in the process. After a number of months maintaining the system, he found a full-time job as a network engineer.

In other words, one way to get Cisco experience is to offer to help for free. Let’s say you’re a Windows expert. Plenty organizations out there need your help, and many of them also have Cisco equipment. Besides doing good by helping a local organization, you can also gain valuable experience that you can list on your resume and use during a technical interview.

#2: Use simulators or rent a rack

Member Rand777 said that one way to get experience is to rent racks of Cisco equipment online. For more information, read my article on the subject, “Rent Cisco practice racks from online providers.”

A less expensive option is to use a Cisco IOS simulator, which imitates a rack of Cisco routers and switches. Here’s list of eight Cisco IOS simulators.

I’ve heard that the CCNA exam has a number of simulation questions these days, so either of these options is a good idea. However, it’s not enough to just pay the money; you have to push yourself to use the equipment to learn more about Cisco networking.

#3: Buy used routers and build a home lab

Member Bill Pate argued that the best way to get experience was to build a home lab. It doesn’t get much better than having your own rack of routers, which can be surprisingly inexpensive. Member wade.alexandro pointed out that you can often pick up 2500 series routers for about $25 each.

#4: Volunteer at work

Member j.s.davis recommended befriending fellow admins at work, and I couldn’t agree more. Perhaps your networking department could use some help shipping routers or taking inventory of hardware. No matter how small the department is, there may be some way you could help and get your foot in the door. An offer of free help can go a long way.

#5: Attend the Cisco Networking Academy

Member c.stockwell recommended attending the Cisco Network Academy. This is an excellent place to start gaining some experience working on real routers and switches. In addition, it’s a great opportunity to network with students, instructors, and potential employers.

#6: Make new friends

Find ways to make friends who use Cisco routers and switches. This is a great way to learn more, gain experience, and maybe find someone who will give you a chance even though you have limited experience. Use social networking on the Web, or join a local Cisco users’ group.

For example, in my area, we have the popular DFW Cisco Users Group. And there are Cisco user groups around the United States and the world.

What if there isn’t a user group in your area? You can start your own group with as few as 10 people and begin receiving benefits from Cisco Press.

#7: Participate in forums

There’s a plethora of Cisco-specific forums on the Internet where you can learn more about Cisco networking. In addition, you can share your knowledge by helping others with Cisco questions. While that doesn’t automatically give you experience, it does get your name out there and help you network with others. Maybe you’ll even meet a future employer by volunteering to help with a networking issue.

Here are some forums I recommend:

• TechRepublic Forums
• Petri IT Knowledgebase Forums
• HappyRouter Forums

#8: Start at the bottom

Member michael.brodock said that one of the best ways to get experience is to start from the bottom. If you really want to break into a new field and get experience, sometimes you’re going to have to suck it up and start from scratch. This often means taking a pay cut and starting over at the bottom of the ladder.

But look on the bright side: The bottom is also where the most openings are, and where you have more opportunity to get into the field.

Summary

Trying to find a Cisco networking position without any experience is very difficult — even if you have a CCNA certification. However, there are many things you can do to network, promote yourself, and gain Cisco networking experience. Don’t get caught in the “chicken or the egg” conundrum.
