Getting started with Unified Access on 3850

My lab environment:  XE 3.6.0

To start playing with 3850 unified access, it is quite simple.  The first thing to do is to enable the web interface.  

1.  First of all, make sure you have your SVI with IP address configured.  In my lab my SVI is VLAN216.

interface Vlan216
 ip address 192.168.24.50 255.255.255.0

2.  Then enable the http and https server on the switch with local authentication.  I have made an assumption here you have already got local user created with privilege level 15.

ip http server
ip http authentication local
ip http secure-server

3. Change the wireless management interface to your management VLAN SVI.  In my lab I am using the same VLAN for simplicity.

4.  Since my lab environment is a single switch environment, you need to change it to mobility controller (MC) so that the access point can join your 3850 controller.  By default it is set as mobility agent (MA)

5.  You can also set your AP country in advance to make sure you use the correct frequency.

Now you can try to access the web GUI via http://192.168.24.50/wireless

Upgrading 3850 IOS-XE software

Just got a chance to play with 3850, the upgrade operation on the 3850 IOS-XE platform is a bit different from traditional IOS.  By default it is booted in "Install" mode, which uses a package provisioning file called packages.conf in flash.  If you want to change it back to the legacy way to do IOS upgrade, you can change to "Bundle" mode, however it is not recommended as additional memory is needed.

You can see the mode from show version.

To upgrade new IOS, you can download the .bin file from cisco.com just like you do it in legacy IOS, then copy it to flash.  Then you can issue the command "software install file flash:cat3k_blablabla.bin" to kick start the installation process.  After reload you will have the new IOS-XE booted.
