Rogue access points, which are access points that are detected by the wireless LAN infrastructure
and determined not to be members of the same mobility group or WLAN system. These are indicated
on WCS location floor maps using a skull-and-crossbones within a black circle

The location-aware Cisco UWN also displays the location of any chokepoints that have been pre-defined
to WCS and the location appliance. Chokepoints are indicated on WCS location floor maps using a blue
star within a grey circle
to WCS and the location appliance. Chokepoints are indicated on WCS location floor maps using a blue
star within a grey circle
. A concentric band of grey around the icon is used to give a relative indication
of the chokepoint range that has been defined in WCS. Note that chokepoint range indication on WCS
floor maps is for display purposes only. The actual chokepoint trigger’s transmission power and range
is configured using the vendor's specific utilities.

Cisco Location Control Protocol
The Cisco Location Control Protocol (LOCP), introduced in software Release 4.1 of the Cisco UWN,
represents a significant step forward in the support of new capabilities between the location appliance
and other components of the Unified Wireless Network. In this release, LOCP augments the traditional
SNMP polling of WLAN controllers and serves as the transport for the telemetry, chokepoint, and
emergency notification features associated with the newly-introduced Cisco Compatible Extensions for
Wi-Fi Tags program.

LOCP is a bi-directional protocol that can be run over a connection-oriented or connectionless transport
and can be secured using Transport Layer Security (TLS). It provides for an ongoing exchange of control
messages that allows either endpoint to determine whether its partner endpoint is still active, as shown
in

and a WLAN controller.
