Figure 45 Multiple Management Domains with a Single Location Domain Each

Three low-end WCS servers provide WLAN management services for an enterprise that consists of a

large headquarters location as well as six extended metropolitan campus locations within a major

metropolitan twin-cities locale. The headquarters location contains 200 access points, and each metro

location contains 100 access points. The design calls for the use of a centralized Cat6500 with two

WiSMs yielding four embedded controllers: WiSM-1 through WiSM-4. WiSM-1 and WiSM-2 service

access points located at the headquarters campus, while WiSM-3 and WiSM-4 service the west and east

metro campus locations respectively. Three Cisco 2710 Wireless Location Appliances are used to track

up to 7500 devices across the entire enterprise, with a maximum of 2500 tracked devices in either the

headquarters, west or east campuses. Location appliance 2710-1 (in red) is assigned to track assets

within the headquarters campus and location appliances 2710-2 (in blue) and 2710-3 (in green) tracks

assets across the west and east metropolitan locations respectively.

To properly configure the multiple management and location domains, you need to first create a campus

location network design on WCS-1 for the buildings and floors that comprise the headquarters campus.

The 200 access points that are registered and split between controllers WiSM-1 and WiSM-2 are

assigned to this network design, and an event notification group is created for the headquarters location.

The network design, controllers WiSM-1 and WiSM-2, and the headquarters event notification group are

all assigned to location appliance 2710-1 and synchronized. In a similar fashion, WCS-2 is used to create

a campus location network design for the buildings and floors that comprise the west metropolitan

locations using controller WiSM-3 and location appliance 2710-2, and WCS-3 is used to create a campus

location network design for the buildings and floors that comprise the east metropolitan locations using

controller WiSM-4 and location appliance 2710-3.

With this design, the entire enterprise is managed as three distinct management/location domain

combinations, with each WCS handling the management polling and reporting for devices within its

respective domain. Location appliance 2710-1 handles polling controller WiSM-1 and WiSM-2 for all

information pertaining to tracked devices found within its location domain, indicated by the red

rectangle. Location server 2710-2 handles polling of controller WiSM-2 with regard to all tracked

devices found in its location domain, which is shown by the blue rectangle. Location server 2710-3
