Configuring AP Detection
By default, AP detection is disabled. To configure AP detection, you must complete
two main steps: you must enable AP detection, and you must configure at least one
radio to scan for APs.
When you configure a radio to scan for APs, you can select one of these options:
■ Single-channel scan for Unapproved APs—If you select this option, the radio
listens for beacons from other APs operating on its own channel. When a radio
hears such a beacon, it forwards information in the beacon to the Wireless Edge
Services zl Module. The radio can send and receive traffic from associated
wireless stations at the same time it listens for beacons from APs.
■ Dedicate this Radio as a Detector—If you select this option, the radio constantly
scans for neighboring APs. Such a radio is called a detector, and it cannot connect
to wireless stations. A detector uses auto channel select (ACS) to change to and
scan all channels that are:
• in its frequency (either 802.11a’s 5 GHz or 802.11bg’s 2.4 GHz)
• allowed by its country’s regulations
Table 12-1 and Figure 12-27 compare single-channel detectors and dedicated detec-
tors.
