Wi-Fi Location-Based Services—Design and Deployment Considerations

Cisco Location-Based Services Architecture
These are all indicated on WCS location floor maps using a skull-and-crossbones within a black circle
as shown in Figure 20. Rogue access points can be totally wireless, connected to the same wired
infrastructure as the detecting WLAN, or connected to an entirely different wired infrastructure. To
display rogue access points on the WCS location floor map, ensure that the “Show Rogue APs” view
option is selected at the top of the floor map display and click Reload in the left-hand column.
Figure 20 WCS Rogue Access Point Location Map
Note that beginning with Release 4.0 of WCS, it is possible to filter the location information displayed
by the WCS based on the age of the information. Thus, in Figure 20, WCS displays location server
information that has aged up to 15 minutes. Alternatively, this value could be set to 2 or 5 minutes for
more recent location information or ½, 1, 3, 6, 12, or 24 hours for less recent information.
Several options are available by clicking on the round, black skull-and-crossbones icon under “View
Filters”:
• The total number of rogue access points detected on this floor.
• Small icons (shown above) or regular-sized icons can be selected. When using small icons, no text
is displayed on the floor map for the rogue access point except when a mouse-over is performed.
When using regular-sized icons, an on-screen tag displaying the MAC address of the rogue access
point appears.
• Either all rogue access points can be displayed, or filtering can be performed to select which rogue
access points to display on the floor map. This is based primarily on MAC address but can be
augmented by filtering on the state of the rogue detection (Alert, Known, Acknowledged, Contained,
Threat, or Known Contained), as well as whether or not the rogue access point was detected to be
connected to the same wired network as the detecting wireless system.
