The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Port security and MAC addresses on managed switch

Asked by Priest04 in Network Switches & Hubs, Network Management, Network Security

How important in real scenario is port security? I have some managed switch and I read in manual that there is an option to limit access to port to certain MAC addresses (you can do this manually, or by learning option). When and why would I use this option? If there is no way to join this network outside the building, would this option remain unused? And If I allow some MAC-A address to access this port, is this the source PC MAC address, or it must contain all the MACs that are in between this switch and a PC? like MAC of some other switch which interconnects these two devices?

Thanks in advance,
Goran
