Figure 22 WCS Rogue Access Point Event History
Detecting APs (Figure 23) gives a tabular view of all access points detecting this rogue access point
along with the RSSI/SNR at which the rogue was detected.
Figure 23 WCS Rogue AP Detecting Access Points
It is important to understand how localization of rogue access points and clients differs from that of
WLAN clients and asset tags. WLAN clients (and asset tags that act as WLAN clients) transmit probe
requests periodically on all channels. Because access points are spending the vast majority of their time
on their assigned channels, probe requests that are transmitted on these channels tend to be detected
rather quickly and relayed to the controllers to which the access points are registered. Multicasting asset
tags such as the AeroScout T2 do not transmit probe requests but transmit their Layer 2 multicasts on
