Cisco Mobility Services Engine (MSE) 8.0 is a wireless mobility and security services engine. It works in conjunction with Cisco Prime Infrastructure instance to deliver these services. After initial build and minimal configuration, most of the other configuration tasks can be carried out through Cisco Prime Infrastructure server.
Cisco Connected Mobile Experience (CMX) is a software package that runs as an application on top of Cisco MSE. In older versions, it is one of the many services offered by the MSE. In the release after Cisco MSE 8.0, the MSE and CMX relationship can be thought of as an underlying hardware platform and a software application running on top respectively.
Enterprise can choose to install a physical MSE appliance and running CMX on top, or CMX can be deployed as VM on a supported virtualization platform. However, if wIPS feature is needed, the older model of MSE acting both as hardware (physical or virtual) and wIPS as a one of the services on top is still needed.
Recently, A pair of MSE 3365 were delivered with CMX 10.4.1 software, while the requirement was to have it use for location services and wIPS. This needed a downgrade to version 8.0 – the latest available as of this writing is 184.108.40.206.
Downgrading to 220.127.116.11
Raise a Cisco TAC case to get a special download link to an ISO file for the 8.0 version. We got 18.104.22.168 with the recommendation to upgrade it further to 22.214.171.124. The ISO is not available on the Cisco download portal for any of the physical platforms
