Is there a best practice document that shows 3500 AP with 5508 controllers? The questions I have are below.
1. Do I configure each AP to non overlapping neighbor channels(1,6,11 for 2.4GHz) or leave that to controller to decide? Does controller change the channel of an AP when it sees congestion on a specific frequency?
2. For 5 GHz is it good idea to bond the channels? What frequency to use for neighboring APs? OR again, leave it to controller to shift as needed?
3. For security what's best practices? 802.1x or different?
