Cisco CCNP / BCMSN Exam Tutorial: Dynamic VLANs and VMPS

Knowledge of Dynamic VLANs and VMPS is important in your efforts to pass the BCMSN exam and earn your CCNP, and it’s also a great skill to have for your networking career.

As a CCNA and CCNP candidate, you know how and why to configure static VLANs. Static VLANs can be a powerful tool for reducing unnecessary broadcast and multicast traffic, but if hosts are moved from one switch port to another, you’ve got to make those changes manually on the switch. With Dynamic VLANs, the changes are made – how else? – dynamically.

The actual configuration of dynamic VLANs is out of the scope of the BCMSN exam, but as a CCNP candidate you need to know the basics of VMPS – a VLAN Membership Policy Server.

Using VMPS results in port VLAN membership changes being performed dynamically, because the port’s VLAN membership is decided by the source MAC address of the device connected to that port. (Yet another reason that the first value a switch looks at on an incoming frame is the source MAC address.)

In my home lab network, I’ve got a host connected to switch port fast0/1 that resides in VLAN 12. What if we had to move Host 1′s connection to the switch to port 0/6? With static VLANs, we’d have to connect to the switch, configure the port as an access port, and then place the port into VLAN 12. With VMPS, the only thing we’d have to do is reconnect the cable to port 0/6, and the VMPS would dynamically place that port into VLAN 12.

I urge you to do additional reading regarding VMPS. Use your favorite search engine for the term configuring vmps and you’ll quickly find some great official Cisco documentation on this topic.

To review, the VLAN membership of a host is decided by one of two factors. With static VLANs, the host’s VLAN membership is the VLAN to which its switch port has been assigned. With dynamic VLANs, it is dependent upon the host’s MAC address.

4 Steps To Downloading Free PSP Games

Do you want to download games onto PSP? Hardly anybody doubts the usefulness and many facets of the Sony PSP, but a lot of people feel that the games themselves are considerably overpriced. If you do your research, you can find the right places and methods to download games onto our PSPs, and we can even do this without breaking the law!

How to Download Games onto PSP- Step 1-
Your standard PSP games will come on disc, or UMD as they are called. As you download games onto PSP however, they will go directly on to a memory stick/card. (Although some people call them memory sticks, and others refer to them as memory cards, there is no difference between the two.) The standard PSP memory card of 32mb will just be big enough to do the job with modern games. PSP owners as a rule should get the biggest and best card within their budget. It is not difficult any more to find reasonable deals on 2 or 4 gig models on eBay and Amazon. When you have acquired your memory card, it will need to be formatted before you can use it. This will effectively wipe the card clean, and is an essential step, so don't leave it out.

How to Download Games onto PSP-Step 2-
One of the biggest problems is finding a place to download the games from. It is not difficult to find places that will let you download games onto PSP, but so many of them are unreliable and dangerous. Apart from the risk of downloading something that will be different from what was promised, you could even find your computer infected with a virus or spyware. Not good! Make sure you find a reputable site to download PSP games from. The trustworthy ones will charge a small fee in advance, and for that you will get access to unlimited downloads.

How to Download Games onto PSP-Step-3-
As you start downloading to your computer, make sure you only download files that end in “PSP” or have “PSP” in the title, as otherwise the file will not be compatible. Sadly it will often be found that the untrustworthy sites out there will trick you with all sorts of different files as downloads, so make sure you are very careful about a file before you download it. A very good idea when downloading the games is to save them to their own folder on your desktop called “PSP Downloads”. This is the most logical place to put them!

How to Download Games onto PSP-Step 4-
Once you have quite a few games downloaded, you can then transfer therm from your PC onto the memory card of your PSP. This is not complicated, and will only need a standard USB cable to connect the two, and the PC should then accept the PSP and think of it as some form of removable drive, like a flashdrive or removable HD. When everything is connected, you need to open up the PSP using the PC and drag and drop the needed files onto the PSP memory stick, just as you would with any kind of removable drive. It is important that as you do this, you put the files into folders marked PSP, and then GAME on your memory card. You must create these files if they are not there already, and it makes sense to use all capital letters.

How to Download Games onto PSP-Step 6-
As soon as you have transferred the games to your PSP, you should be able to play them by opening up the GAME menu and choosing the game you want from the stick. You may get error massages, and these are often caused by incompatible firmware. This happens most often with downloading homebrew games. It can mean that you have to downgrade the firmware for your PSP to be able to play these homebrew games.

It really is quite easy to download games onto PSP when you have learned how to do it, the hardest part is finding a reputable download source!

3 Tips for Sending Special Messages

Staying in touch with family and friends has never been easier with the speed and efficiency of today's technology. We live in a world of e-mail, text and instant messages and mobile conversations.

While such options make it easy to stay in touch, these technologies have also lessened the emotional aspect of our communications.

Here are a few suggestions on how to use technology to stay close to loved ones and, at the same time, bring back the personal element in your communications.

* Send a personal DVD message. Now you can give the gift of vivid, colorful memories by creating personalized DVD messages for your friends and family. It's a fast, easy and fun way to stay in touch.

Can't make it to your high school reunion? Use a Sony DVD Handycam camcorder to record a special message to old classmates. You can even get special Sony DVD mail envelopes to share your discs.

Encourage friends and family to reciprocate. When you receive their DVDs, just pop them into your player as you would a movie.

* Make a Webcam chat date. A picture tells a thousand words, but real-time video speaks volumes. While nothing can replace an in-person conversation, you can get awfully close to the real thing with a Webcam chat.

Gather your loved ones in front of the Webcam to talk, view photos or share advice.

First time carving the turkey? Get Dad on the Webcam - he can probably walk you through it. Schedule your chat on a special occasion - perhaps on a birthday or holiday - and don't forget to plan your next one. You can even make it an annual event.

* Create a video file on your digital still camera. Forgot your mom's birthday or couldn't attend your child's school play? Send your loved ones a video clip so that they'll know how much you care.

Be creative, shake things up and share your ideas. It's never been so easy to "be there when you're not." - NU
