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!

Data center switching problem

Asked by Sam_Rendell in Network Switches & Hubs, Networking Hardware Firewalls

Tags: VLAN, switches

Hi peoples,

I have a problem with some switching in my data centre.

I have two firewalls which are supposed to run in HA, they are joined by two switches. Switch one takes LAN and splits it to the two FWs switch two takes WAN form the FWs and joins them. It works fine in my office, if I connect a lappy to the LAN switch it can see both firewalls and out the other side of the WAN switch.

However when I put the switches and FWs into the data centre they can not be seen. With just one FW in place (as I have left it) everything works fine so I assume it is something to do with the switches and VLANs in the DC but I don't know much about VLANs!

The switches I am using do support VLANs however as suggested to me previously they are both using ID 0 (no VLAN) I believe they are only layer 3 switches.

Thanks for reading,
Sam.
