[pe1egrim]

Hello! I got new cisco 3850 yestarday and i should configure this device as wireless controller. I read some manuals and in each manuals was mantioned that for configuration Cisco 3850 as wireless controller i should use this command "wireless mobility controller". But my cisco don't understand this command and dont have association any commands with word wireless? What i done wrong? Device has active IP Base license.

Hi, The software you are running does not support the wireless controller.Cisco are dropping the wireless controller feature after 16.3. If you need wireless, you will have to downgrade to 16.3 Thanks John

Can i change to Release 3.6.6E? Can I encounter with some problems, when i change firmware from 16.6.3 to 3.6.6E ? Could you explain difference between firmwares 16.x.x and 3.x.x ?

Hi, 

You should be fine downgrading to 3.6.6E as long as your switch supports that version. Follow the downgrade  to 3.x steps in the release notes at the following link:

To find the difference between 16.6.3 and 3.6.6E, use the Cisco Feature Navigator:

Hey John.

Thanks for the info - can confirm that I upgraded from 3.xxx to 16.12 and had this issue.

Downgraded too 16.3.8 and works a treat.
