Using a Third-party Location-based Solution

On the controller, configure the AeroScout/Ekahau/Centrak server IP address and enable the location-based service. When using AeroScout or Ekahau, the location-based server is aware of the controller IP address. And if using AeroScout, the controller notifies the AeroScout server of the operational APs.

Enable the location-based service on the APs that you want to participate.

Note

Participating APs must use the 2.4 GHz band and the radio that receives location-based service tags must have at least one WLAN service associated with it.

Once you have enabled the location-based service on the controller and the participating APs, at least one of the participating APs will receive reports from a location-based service Wi-Fi RFID tag in the 2.4 GHz band. The tag reports are collected by the AP and forwarded to the location-based server by encapsulating the tag reports in a WASSP tunnel and routing them as IP packets through the controller. When using Ekahau or Centrak, the controller does not converse directly with the location-based service server.

Note

Tag reports are marked with UP=CS5, and DSCP = 0xA0. On the wireless controller, tag reports are marked with UP=CS5 to the core (if 802.1p exists).

An AP‘s tag report collection status is reported in the AP Inventory report. For more information, see Viewing Routing Protocol Reports.

If availability is enabled, tag report transmission pauses on failed over APs until they are configured and notified by the location-based server. With an availability pair, it is good practice to configure both controllers with the same location-based service.

When location-based service support is disabled on the controller, the controller does not communicate with the location-based server and the APs do not perform any location-based functionality.

Ensure that your location-based service tags are configured to transmit on all non-overlapping channels (1, 6 and 11) and also on channels above 11 for countries where channels above 11 are allowed. For information about proper deployment of the location-based solution, refer to the third-party documentation (AeroScout/Ekahau/Centrak).
