Technology Overview
Cisco CleanAir Technology
Cisco CleanAir is the integration of Cisco Spectrum Expert technology with
Cisco CleanAir is the integration of Cisco Spectrum Expert technology with
a Cisco access point. Before Cisco CleanAir was available, operators had to
walk around with an instrument to detect chosen signals and physically locate
the device. Cisco CleanAir helps to automate these tasks within the system man-
agement function by adding additional intelligence over Spectrum Expert, and
thereby augmenting the overall experience by proactively reclaiming control
over the spectrum.
The components of a basic Cisco CleanAir technology are the Wireless LAN
The components of a basic Cisco CleanAir technology are the Wireless LAN
Controller and the Cisco 3500 Series access points. To take advantage of the
entire Cisco CleanAir feature, the Cisco WCS can display in real time the data
retrieved from Cisco CleanAir. Adding the Mobility Services Engine (which is
addressed in a separate guide) further enhances the available features and pro-
vides the history and location of specific interference devices.

Wireless Control System
Cisco WCS enables you to configure and monitor one or more controllers and
associated access points, to monitor and troubleshoot radio technology, and to
visually display Cisco CleanAir data to the network administrator. Cisco WCS
includes the same configuration, performance monitoring, security, fault manage-
ment, and accounting options used at the controller level and adds a graphical
view of multiple controllers and managed access points.
Cisco WCS runs on Windows 2003/SP2, Windows 2003 R2/SP2 32-bit instal-
Cisco WCS runs on Windows 2003/SP2, Windows 2003 R2/SP2 32-bit instal-
lations, and Red Hat Linux Enterprise Server 5.0 32-bit installations. On both
Windows and Linux, Cisco WCS runs as a service, which runs continuously
and resumes running after a reboot. The configuration in this guide runs the
Windows 2003 Operating System within a virtual machine and leverages
VMware ESXi 4.0 within the data center.

Mobility Services Engine
The Mobility Service Engine (MSE) can run multiple related or independent
services such as location and wireless IDS/IPS services, the CleanAir database
functionality, as well as future services. The MSE is an independent appliance
and is leveraged by the Cisco WCS. The MSE and the services it supports are
discussed in another supplemental guide.
Location or Context-Aware
The Cisco location service solution (also referred to as the context-aware service)
The Cisco location service solution (also referred to as the context-aware service)
provides the capability to determine the physical location of a tracked entity in
the network and additional contextual information such as the serial number of
the tracked entity. The tracked entity can be a wireless endpoint, a wired end-
point (a phone or PC), a wired switch, or a wireless controller. Location information
is critical for wired endpoints. For example, a phone in the lobby of an office
building can have different policies from a phone in a conference room or in an
employee office. Today, the policies are statically administered based on the
MAC address and not based on the location of the endpoint itself. Knowing the
location of a wired entity provides additional intelligence to push the right set of
policies to tracked devices based not only on the user’s credentials and MAC
address, but also on the location of the device. This document does not cover
the location service solution; this information is presented in a different supple-
mental guide.
Configuration Details
This Cisco Wireless Control System requires having Windows 2003 Server
loaded, and within the SBA architecture, we have loaded Windows 2003 Server
on a VMware ESXi 4.0 platform. This document leverages the standard server
configuration that supports up to 2000 Cisco Aironet lightweight access points,
1000 standalone access points, and 450 Cisco wireless LAN controllers. A low-
end server can support up to 500 Cisco Aironet lightweight access points, 200
standalone access points, and 125 Cisco wireless LAN controllers. This information
can help you determine your network needs and future growth. No matter what
your organization requires, it is the same Cisco Wireless Control System software
that runs on different hardware, as described in the product Release Notes.

The Mobility Solutions Engine (MSE) can be leveraged within the CleanAir solu-
tion to create an Interference History. Many issues that occur in the day-to-day
operations of a Wireless Network are intermittent and often hard to track down.
Leveraging the power of the MSE, you can track an issue by the time of day and
build upon the historical data that can help mitigate these difficult, if not impossible,
network interference devices.
Initial Configuration of the MSE
Step 1:
Step 1:
Connect your console cable to the console port of the MSE.
Step 2:
Power on the Mobility Services Engine.
