In simple terms, Converged Access deployment controller functionality split into two
MA - Terminate CAPWAP, keep client database entries
MC - RRM, Mobility, etc
By default 3850 is MA when you configure a wireless management interface on it. You need to have MC +MA (within the same switch stack or cetralized MC & distributed MAs) to get the system working. You need to have AP licence only on MC & not in MAs.
3700 AP to work you need to have IOS-XE 3.3.2 ( includes support for Z regulatory domain as well). 3850/3650 supports POE+
Rasika - Thanks for the link. I've started reading it - having gotten all the way through yet.
On a broader topic regarding the new 3850/wireless architecture; What is the recommended archecture? For example; is Cisco encouraging us to use the MC functionality on the 3850s at remote branches and small offices and a dedicated controller at main campus or is Cisco encouraging us to eventually replace all our controllers and go to a 3850 MC architecture.
Thanks for the response. So, in a large Main Campus best practice is to stick with the old controller. When 3850s are used at the Main Campus we should configure 3850s as MA. At small remote branches we should configure 3850s as MC.
When using the 3850 as an MC we will have to purchase licenses for access points, correct?
When purchasing licence for 3850, it is only required for MC switch stack. No licence required for MAs. Lets say you have max 20APs at branch, then you can purchase single 3850 with 20 AP license & all other 3850 (if required) without any AP license.
Yes, 3850 is performance enhanced switch & that should be a good replacment for any of the existing access layer switch models (wether you use WLC functionality or not)
Mainly 3850 in Converged access will give you the flexibility of treating wired & wireless traffic in same way for QoS & Security policy (since capwap terminate on MA at access layer, no more capwap tunnel back to your distribution layer WLC)
Also 802.11ac (1Gbps wireless) is another reason to terminate capwap at your access layer. Otherwise all these capwap goes back to 5508 & it will become the bottleneck (8Gbps max for all your APs)
Also improved roaming performance (within a SPG ) is another advantange
Netflow & other features are additional pluses of the CA.
Here is a very good presesntation of this CA architecture to understand the concept. This is from CiscoLive melbourne event held a week back.

This is the start of a display filter cross reference between Wireshark and OmniPeek.
The 1st installment is a table of advanced filters. More filters will be added as time allows.

I have created a Powershell script to automatically add a Wireless Guest User on Cisco WLCs. (tested on 2500 Series)
The script should be completely self explanatory.
