Head over to and in the Software Download section, search for your model of access point that is acting as the Mobility Controller. If your server is very somewhat locked-down, also take a look at the Permissions settings for the TFTP-Root folder and make sure it can be accessed by outside sources (giving the “Everyone” entity read-permissions is usually enough). Make sure the local firewall on your server is permitting TFTP traffic from the Mobility Express controller's IP address. If you have a network firewall between your Mobility Express Controller and your TFTP-server, make sure that UDP port 69 is allowed from the Mobility Express Controller’s IP address to the server’s IP address. The default installation settings created the directory C:\TFTP-Root\ on my server and any file placed in this folder will be available for download using TFTP. In my case, I installed the TFTP-server on a Windows server.

I used the free TFTP-server from Solarwinds, which you can easily find using your search engine of choice. Start by installing a TFTP server on your network. In my case, I needed both an AP-2802 and an AP-2702 to join an AP-2802 acting as Mobility Express Controller, but you can of course have a deployment consisting of only a single access point model. To illustrate the process of making other access points join your Mobility Express deployment with access point images being stored on a separate TFTP server, take a look at the topology image below.

There is also a mode where you connect your Mobility Express Controller to to automatically download access point images on the go as needed, but that requires having an active SmartNet contract tied to the serial number of your access points, which is a whole other story and not covered in this article. Without a TFTP server up and running on your network, other access points (even if they are the same model as the access point acting as the Mobility Express Controller) will not be able to join your deployment. This is why the storing part is instead handled by a separate TFTP server that needs to be installed on your network.

In Mobility Express, however, the storing part has to be moved to a separate TFTP server because an access point acting as a Mobility Express Controller does not have enough resources to store and manage all of the different kinds of images needed in networks that are running lots of different types of access points. In a normal WLC deployment, the WLC itself is in charge of storing and distributing appropriate software images to all access points in the deployment. One of those things is access point software image management.

Using the Mobility Express technology, you can configure most of the common settings found in a typical office wireless network, but since a simple access point is the one in charge, there are of course some features that are not available to their full extent. This article does not cover the process of converting a regular Cisco Access Point to Mobility Express Controller mode, there are already plenty of guides out there about that.įor those that don't know, Cisco Mobility Express is a wireless deployment method where instead of using a separate wireless controller (also called WLC, which includes the 3504, 5520, 8540, and the newer 9800 models) to control and configure all of your access points (APs), a single access point is converted to a so-called Mobility Express Controller and after that acts as the single point of management for all the other access points in the network. Recently I spent some time setting up a Cisco wireless network using their Cisco Mobility Express technology and in this article, I'd like to highlight some "gotchas" I ran into regarding access point software images while putting the network together.
