Rogue AP Detection
Cisco Small Business WAP121 and WAP321 Wireless-N Access Point with PoE 70
5
The WAP device performs an RF scan on all channels to detect all APs in the
vicinity of the network. If rogue APs are detected, they are shown on the Rogue AP
Detection page. If an AP listed as a rogue is legitimate, you can add it to the Known
AP List.
NOTE The Detected Rogue AP List and Trusted AP List provide information that you can
use to take further action. The AP does not have any control over rogue APs on the
lists and cannot apply any security policies to APs detected through the RF scan.
When AP detection is enabled, the radio periodically switches from its operating
channel to scan other channels within the same band.
Viewing the Rogue AP List
Rogue AP detection can be enabled and disabled. To enable the radio to collect
information about rogue APs, click Enable next to AP Detection and then click
Save.
Information about detected and trusted rogue access points appears. You can
click Refresh to refresh the screen and show the most current information:
