      Just wanted to verify that the 2100 Controller can support clean air
      according to cisco
      CleanAir 7.0 software is supported on all of Cisco's shipping controllers.
      the config guide lists clean air as an option

      http://www.cisco.com/en/US/products/ps7206/products_installation_and_configuration_guides_list.html

      The basic Cisco CleanAir architecture consists of Cisco CleanAir enabled APs and a Cisco WLAN controller (WLC). Cisco Wireless Control System (WCS) and Mobility Services Engine (MSE) are optional system components. In order to get full value from the information that the CleanAir system supplies, the WCS and MSE together are key to leveraging a wider efficacy of CleanAir. This provides user interfaces for advanced spectrum capabilities such as historic charts, tracking interference devices, location services and impact analysis.

      An AP equipped with Cisco CleanAir technology collects information about non-Wi-Fi interference sources, process it and forward to the WLC. The WLC is an integral core part of the CleanAir system. The WLC controls and configures CleanAir capable APs, collects and processes spectrum data and provides it to the WCS and/or the MSE. The WLC provides local user interfaces (GUI and CLI) to configure basic CleanAir features and services and display current spectrum information.

      The Cisco WCS provides advanced user interfaces for CleanAir that include feature enabling and configuration, consolidated display information, historic Air Quality records and reporting engines.

      The Cisco MSE is required for location and historic tracking of interference devices, and provides coordination and consolidation of interference reports across multiple WLCs.

      Note: A single WLC can only consolidate interference alerts for APs directly connected to it. Coordination of reports that come from APs attached to different controllers requires the MSE which has a system wide view of all CleanAir APs and WLCs.

      Cisco CleanAir Benefits with Mobility Services Engine

      CleanAir is an effective tool to monitor and manage your network's RF conditions. The Cisco Mobility Services Engine extends those capabilities by providing:

      The ability to track and trace CleanAir interferers and Layer 1 exploits across your entire RF spectrum
      Systemwide interferer details and event correlation
      Zone of impact and interferer notification
      Self-healing mitigation of interferers

      A wireless network that consists of Cisco Aironet 1260 APs and Cisco 2100 Series WLC has been correctly configured with Cisco WCS version 7, which is also used for management. The CleanAir [Zone of Impact] is[not visible] for the respective Cisco WCS maps.

      1260AP is not clean air
      2100 wlc supports clean air with version 7
      Zone of impact is a MSE function of triangulation using 3 or more aps

      @ Luis Cifer
      the answers are: AP and MSE? if they're correct, I'll upload the new vce file.
      Thanks!

      Exam A – Q110
      Zone of Impact – implies MSE
      AP must be clean air capable – the 1260 is does not have clean air chip
