Hi, I have a wireless configuration that works great for me. I have a small wireless network of 5 different offices with 5 AP's. I have all Cisco AP's using Microsofts IAS as my RADIUS server, and group policy to push out the wireless configurations to my windows clients.
What I'm wanting to do is make my secondary domain controller, my secondary IAS (RADIUS) server. I've configured my IAS settings on the secondary server identical to my primary DC. I need to know if what I'm looking at changing in my AP configuration will give me the results I'm looking for.
What I want to do is configure my access points so that if my primary domain controller goes offline, then my secondary controller will start authenticating to the AP's. I'm wondering if all I need to do is add the secondary server to my aaa radius server group. Or do I need to add it as the radius-server host, or both. Or is what I'm trying to do even possible with how I'm trying to do it?
Let me know if I need to provide any more information to make my goal or what I'm working with more clear.
