I am trying to configure the Cisco 521 Access Point & 526 Mobility Controller for a Guest Access Solution. I am wondering if it is necessary to use the CE520 switch (to connect the access points) or i can use any other switch since since both in the Cisco 500 Series Wireless Express Mobility Controller Configuration Guide and in the CCA setup wizard is written that the switch ports to which you connect your access points must be configured as access point smart ports. I tried to connect the 526 controller and the 521 access point to a CE520 switch but the IPs from my DHCP server (a Cisco 1841 router) couldn't pass through! Actually the switch got an IP but the access point and the PC couldn't. All devices were in the same-default vlan.
On the other hand when I connected them on a d-link unmanaged switch the access point (and the PC) obtained the IP automatically from DHCP but it couldn't retrieve any other information from the controller. It was reloading all the time! The messages from the CLI are on the attached document.
