Product and Software: This article applies to all Aruba controllers and ArubaOS versions.
The basic function of an AP in AP mode is to serve the clients.
If the distributed design and the load of traffic allows, an AP scans the channels of the same band to find the best signal strength and lower bit error rate. An AP can also detect rogue APs that operate on the same channel.
If a rogue AP is detected, the AP can deny service to the rogue AP. However an air monitor (AM) is more effective in this situation. The primary job of the AP is to serve clients. So, if an AP receives an association request from the client, it stops denying service to the rogue and serves the client.
Aruba recommends that you deploy AMs to detect and disable rogue APs effectively.
