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.

How do I configure DHCP for two WLAN's on Cisco 2100 Wireless LAN Controller?

Asked by sfjcpu in Wireless Local Area Network, Dynamic Host Configuration Protocol (DHCP), Miscellaneous Networking

Tags: Cisco Aironet 1130AG Series, Cisco 2100 Series Wireless LAN Controller, DHCP, Sonicwall

I have a Cisco 2100 Wireless LAN Controller with three Cisco 1130 Lightweight Wireless Access Points. I have two WLAN's configured on this wireless system, with one being on the same VLAN/Subnet as the rest of the network (private), and the public side being on VLAN 20 (public). Two of the AP's are connected directly to the WLC, while the third is connected to a Cisco switch.

I'm trying to get DHCP configured on both WLAN's. It's working on the private side, but not on the public side. I've double-checked my configs and made sure there's communication between the access points, DHCP server, and WLC using ping. There are no access control lists implemented currently. My question is, do I need to put the public WLAN interface on a different physical port than the management (private) interface? As it is, I have both VLAN's/subnets going through the same physical port and only the management (private) interface is pulling DHCP IP addresses. I am currently using a Sonicwall to supply DHCP addresses.
