Cisco CCNA / CCNP Exam Tutorial: Five Debugs You Must Know

To pass the BSCI exam and move one step closer to CCNP certification success, you ve got to know how and when to use debug commands to troubleshoot and verify network operations. While you should never practice debug commands on a production network, it s important to get some hands-on experience with them and not rely on "router simulators" and books to learn about them.
When it comes to RIP, "debug ip rip" is the primary debug to use. This debug will show you the contents of the routing update packets, and is vital in diagnosing RIP version mismatches and routing update authentication issues.
You know how to use the variance command to configure unequal-cost load-sharing with IGRP, but IGRP has no topology table that will give you the feasible successor metrics you need. With IGRP, you need to use the "debug ip igrp transactions" command to get these vital metrics.
Several factors are considered by OSPF-enabled routers when it comes to forming adjacencies, including hello and dead timer settings. If an adjacency doesn t form when you think it should, run "debug ip ospf adj". The reason the adjacency isn t forming is usually seen quickly with this command s output.
Let s not ignore Layer Two! If frame relay mappings are not forming according to your configuration, run "debug frame lmi". This debug will allow you to quickly diagnose and correct any LMI mismatches.
When it comes to PPP, it can be very frustrating to try to spot a problem with a password or username. Instead of staring at the configuration for 10 minutes, run "debug ppp negotiation" and send a ping over the link. This command will help you spot the router with the misconfigured username or password, not to mention saving you a lot of time!
Effectively using debugs during your CCNA and CCNP exam study will help you truly understand what s going on "behind the command" - and it will really come in handy on that day when your production network just isn t doing what you (think) you told it to do!

Dreams of a New Laptop

I want a new laptop. I want my new laptop will be a new, bright and with keys that feel like magic when you press on them and screen resolution second-No. I want to be able to watch my favorite dvds on my computer and see the sweat Bruce Willis in the eye with crystal clear clarity that he dives with another bomb. I want an infinite memory and amazing speed. I want to be able to shoot down a government with it, if I so choose. And play a good game of solitaire too.
There a laptop computer that I think could do all those things, except perhaps to overthrow the government, I think I will have to buy software to do so. ASUS Lamborghini VX2 series VX274UL Intel Core Duo T7400, 2.16GHz (VX274ULYL). Now, I totally did not know that any of this means. I do not techie. I know how to switch to my computer, install some programs, and that their use of it. Jargon is for me. But he said, Lamborghini series that got to be good, and it costs $ 3896 that were to be good, too. If the price is anything to go by him were extremely well, I think. My friend that the laptop cost $ 7792 or so he told me. That would be extremely cool. This probably comes with the software already installed government usurpation. As tempting as this kind of power, I think I will stick with Lamborghini series. Want to start slowly work my way up.
Besides Lamborghini series of nice things said, as " 8 X Super Multi Scribe Light & quot; " and Colour Shine WXGA + wide screen & quot;. And it was built in Webcam. I do not know what I would do with the Webcam. I am very camera shy and very private, the idea of the general public to show my home makes me want to cringe, but I am sure that as soon as I got it, and once I learned how to use it, I never know how I lived without it . I like the sound, while the wide screen, color and brilliance. Should be promising on the resolution front, or this is my ignorance of computer jargon beginning to show? I& 39;m also hoping that at some point someone explain to me exactly, or even in rough outline, what is the GeForce . I will not even guess danger. People will laugh.
I go to the cafe with my new laptop smart, wifi friendly cafes, of course, open it and smile condescendingly at all envious looks that come to me. I accidentally stretch my arms, my fingers, press, and keep them above my magic keyboard while everyone has their breath with anticipation. And then I will order latte and play an active mine minesweeper game. I am very good. My time for the experts are not too bad.
Unfortunately my new laptop only a dream. So much desired Lamborghini series is in any case. Something much more realistic for my meagre budget is the main little HP Intel Celeron or Acer TravelMate or LG Intel at $ 714 - $ 779 price range. And you want to know something? I would like to make her pieces. They say things like " Graphics Media Accelerator " and " WXGA screen & quot;, and they are accompanied by a lot of figures that are absolutely means nothing to me. I am absolutely boggled at the jargon, and I like it. So if your screen resolution is not so brilliant as well 4k laptop. I bet Bruce Willis in sweat will still look just as fab to me. The resolution is so good on all the computers in those days that I probably will not be able to tell the difference anyway. With respect to the memory and speed, I have simple needs and so I do not need a gazillion gigabytes of memory. If I need more, I will get more. I understand that this is possible. So if I can not take over the world (I can always upgrade). I bet a keyboard will still magic and that I can still play a killer game of solitaire.

Remote Data Backup

The term remote backup data is used in two senses. One concerns the storage of data on CDs and cassettes and transporting them to remote offices. The other is about the use of online backup to data to remote installations. Individuals and companies can either of the methods. However, online backup has certain advantages over the traditional method of transport of data on physical offices.Data remote backup is essential to prevent the loss of productivity due to lost data. Data can be lost during the planned system upgrades or because of system failure, theft, fire, virus attack, and a variety of other reasons. A backup on your own computer is useless in the case of these events. It is therefore necessary to store data in remote locations. The traditional method is still followed by many companies. But it is expensive because backup personnel, transport, and well-equipped offsite warehouses to be. It also takes time to change tapes, backup and staff may not be available on weekends and holidays for this task. Similarly, data recovery from the camp can be difficult, on weekends and holidays. Online data backup is gradually replacing the traditional method. It can be used for both laptops and computers. In this method, an individual or a company commissioned the services of a company, client stores data in remote locations, using on-line data backup. An Internet connection is all what the client needs. Software is installed, the service provider, with the installation take less than an hour. The data are either transferred, as they are created or modified, or at a scheduled time, daily. In this type of remote data backup solution, data is encrypted so, the service providers do not have access to the client data. In addition, several versions of a file for recovery. Data transmission is monitored and managed recovery of IT professionals is located on the remote system. These remote facilities are equipped with network equipment, UPS, generators, and fire protection tools. Since the service is available around the clock, the data can be restored, even on weekends and holidays. In addition, the data can be accessed during the trip and at the customer sites.

What Is Really Behind Your PC s Poor Performance

Keeping a computer running smoothly and quickly is a never-ending job. It seems like no time after you take your brand-new PC out of the box, your computer starts acting up and performing more like the old PC you got rid of than the new one it is supposed to be. While this is extremely frustrating, it can be prevented if you know what is causing your PC s poor performance and how to fix the problems behind it or avoid them in the first place.
The nastiest things that corrupt your PC are the things you can t see. Nasty bugs like viruses, adware and spyware can wreak havoc with your system without you even being aware of it. At their most lethal, viruses can completely destroy your PC s operation, but normally they just work to interfere with the daily operations of your computer. Adware and spyware, on the other hand, stay running in the background of your PC and can slow it down considerably.
Here s a closer look:
Computer viruses are PC software programs that you accidentally download to your computer through an email attachment or other type of download. Once installed on your computer, a virus can interfere with your PC s operation; record, corrupt or delete data; and spread itself to other computers through your network or the internet.
Spyware and adware are software programs that you download onto your computer along with many other software applications. This software is then used to track your online browsing habits so that you can be hit with pop ups that you will be more likely to respond to. Not only is this software an invasion of your privacy, it also can compromise your data and affect your PCs performance.
Not only can things that you download from the internet onto your computer affect its performance, software that is already installed or software that you install through your CD drive can also create problems. You see, some software that you have on your PC stays running in the background even if you are not using the program. This can dramatically affect your PC s execution times, especially if there is more than one hidden program running. To see if you have programs running in the background, press Ctrl + Alt + Delete at the same time. The box that pops up will show you all applications that are running.
Other things that can affect your PC s performance include a hard drive that is too full, not enough memory to perform tasks and a fragmented hard drive. All of these problems can be solved by performing routine maintenance on your PC or purchasing a software package that does it all for you. If you choose to do it yourself, you will need to manually go into your Windows System Tools and launch each program. Here you will find several system optimizers to help you free up your disk space, defragment your PC, and detect and repair disk errors.
Even the process of adding and deleting programs can affect your PC s performance. When you install and uninstall Windows programs, they leave behind parts or applications that can slow down your computer. You may even unknowingly delete a file needed for other software applications. This can result in a minor glitch or a complete failure with some programs or even your whole system.
Keep Your PC Performing Like New
One of the first things that you should do to protect your PC s performance is install a firewall if you don t already have one and use adequate security software to prevent intrusions. You should also have additional spyware and adware detectors if your security software does not have them.
You can also purchase additional software that will keep your system optimized on a regular basis and take care of all of the problems that we talked about. This is an advantage over doing it yourself because it is very easy to forget to perform maintenance, and let s face it; who has time to manually perform all of these functions?
You should also get a free hidden error scan to see if your PC is operating with any hidden errors that can ruin your PC s performance. Since 94% of computers do have hidden errors, yours probably does too, but hidden errors are easy to eliminate with the right software.
With all of these things that can affect your PC s performance, there is no wonder that it continually loses efficiency over time. But you can prevent it, if you stay on top of it.
