Configuring Cisco CleanAir on Cisco WLC (GUI)
Choose Wireless > 802.11a/n/ac or 802.11b/g/n > CleanAir to open the 802.11a (or 802.11b) > CleanAir page.
Check the CleanAir check box to enable Cisco CleanAir functionality on the 802.11a/n or 802.11b/g/n network, or uncheck it to prevent the Cisco WLC from detecting spectrum interference. By default, this feature is in disabled state.
Check the Report Interferers check box to enable the Cisco CleanAir system to report any detected sources of interference, or uncheck it to prevent the Cisco WLC from reporting interferers. By default, this feature is in enabled state.
Check the Persistent Device Propagation check box to enable propagation of information about persistent devices that can be detected by CleanAir. Persistent device propagation enables you to propagate information about persistent devices to the neighboring APs connected to the same Cisco WLC. Persistent interferers are present at the location and interfere with the WLAN operations even if they are not detectable at all times.
Ensure that any sources of interference that need to be detected and reported by the Cisco CleanAir system appear in the Interferences to Detect box and any that do not need to be detected appear in the Interferences to Ignore box. By default, all interference sources are detected. The possible sources of interference that you can choose are as follows:
Configure Cisco CleanAir alarms as follows:
Trigger spectrum event-driven radio resource management (RRM) to run when a Cisco CleanAir-enabled AP detects a significant level of interference as follows:
