Just to be clear, this posting is NOT asking for help. This is a posting to help those with the HARDWARE side of the configuration. This is what I just finished doing in my lab for testing. Worked great. DHCP, WLAN Advertising, etc. I now have to go on to the next harder steps of really combing through the WLC configuration, applying our standard template configurations for our Routers/Switches, applying dual and tertiary redundancy with regards to routing, DHCP via MICROSOFT and not using a switch, and so on.
This was just meant to help those who don't have a lot of experience configuring the router switch environment. Sorry if I confused any one.
