Which devices can be tracked with the Cisco Context Aware Services?

CAS uses the MSE to collect device information from wireless LAN controllers for Wi-Fi clients and from wired network infrastructure via SNMP and other mechanisms for wired endpoints, enabling comprehensive tracking of any device visible to the network regardless of connection type.

Restricting tracking to only wireless devices ignores CAS's integration with wired switches and routers, which allows it to detect and track wired endpoints as well.

Restricting tracking to only wired devices overlooks the primary and most granular use case of CAS, which is location tracking of wireless devices using AP RSSI and triangulation data.

CAS does not require devices to be Cisco-certified; it tracks any device that associates with the wireless infrastructure or is visible to the wired network, regardless of vendor or certification.
