Rogue detection can detect different types of devices in a WLAN network, for example, rogue APs,
rogue clients, rogue wireless bridges, and ad-hoc terminals. An AP can work in either of the following
modes for rogue detection:
Monitor mode: In this mode, an AP scans all 802.11g frames in the WLAN, but cannot provide
WLAN services. As shown in Figure 42-1 , AP 1 works as an access AP, and AP 2 works as a
monitor AP to listen to all 802.11g frames. AP 2 cannot provide wireless access services.
