Provides answers to frequently asked questions about Cisco CleanAir, addressing common operational scenarios, troubleshooting steps, and best practices for efficient RF interference management.


Q. 

Multiple access points detect the same interference device. However, the device shows them as separate clusters or different suspected devices clustered together. Why does this happen?

A. 

Access points must be RF neighbors for the device to consider merging the devices that are detected by these access points. An access point takes time to establish neighbor relationships. A few minutes after the device reboots or after there is a change in the RF group, and similar events, clustering will not be very accurate.

Q. 

How do I view neighbor access points?

A. 

To view neighbor access points, use the show ap ap_name auto-rf dot11{ 24ghz | 5ghz} command.

This example shows how to display the neighbor access points:

Device#show ap name AS-5508-5-AP3 auto-rf dot11 24ghz
