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 xl 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 13-1 and Figure 13-27 compare single-channel detectors and dedicated
detectors.
