Software upgrade Cisco Wireless LAN Controller

Start by transfering new code to the Wireless LAN Controller. Initiate predownloading by doing the following. Basically you’re setting the new SW as backup, and telling the APs to download the new SW, before setting the backup SW as primary.

(Cisco Controller) >config ap image predownload primary all

(Cisco Controller) >show ap image all

Disabling AironetIE on Cisco Mobility Express

The Mobility Express APs from Cisco run a type of software, which also contains an onboard Wireless LAN Controller. Contrary to most standalone WLCs from Cisco (2504, 3504, 5520, and so on), the Mobility Express controller GUI is simpler and more modest.
