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:

• Bluetooth Paging Inquiry—A Bluetooth discovery (802.11b/g/n only)
• Bluetooth Sco Acl—A Bluetooth link (802.11b/g/n only)
• Generic DECT—A digital enhanced cordless communication (DECT)-compatible phone
• Generic TDD—A time division duplex (TDD) transmitter
• Generic Waveform—A continuous transmitter
• Jammer—A jamming device
• Microwave—A microwave oven (802.11b/g/n only)
• Canopy—A canopy bridge device
• Spectrum 802.11 FH—An 802.11 frequency-hopping device (802.11b/g/n only)
• Spectrum 802.11 inverted—A device using spectrally inverted Wi-Fi signals
• Spectrum 802.11 non std channel—A device using nonstandard Wi-Fi channels
• Spectrum 802.11 SuperG—An 802.11 SuperAG device
• Spectrum 802.15.4—An 802.15.4 device (802.11b/g/n only)
• Video Camera—An analog video camera
• WiMAX Fixed—A WiMAX fixed device (802.11a/n/ac only)
• WiMAX Mobile—A WiMAX mobile device (802.11a/n/ac only)
• XBox—A Microsoft Xbox (802.11b/g/n only)

Configure Cisco CleanAir alarms as follows:

1. Check the Enable AQI (Air Quality Index) Trap check box to enable the triggering of air quality alarms, or uncheck the box to disable this feature. By default, this feature is in enabled state.

2. If you checked the Enable AQI Trap check box in Step a, enter a value between 1 and 100 (inclusive) in the AQI Alarm Threshold field to specify the threshold at which you want the air quality alarm to be triggered. When the air quality falls below the threshold level, the alarm is triggered. A value of 1 represents the worst air quality, and 100 represents the best. The default value is 35.

3. Enter the AQI Alarm Threshold (1 to 100) that you want to set. An alarm is generated when the air quality reaches a threshold value. The default is 35. Valid range is from 1 and 100.

4. Check the Enable trap for Unclassified Interferences check box to enable the AQI alarm to be generated upon detection of unclassified interference beyond the severity threshond specified in the AQI Alarm Threshold field. Unclassified interferences are interferences that are detected but do not correspond to any of the identifiable interference types.

5. Enter the Threshold for Unclassified category trap (1 to 99). Enter a value from 1 and 99. The default is 20. This is the severity index threshold for an unclassified interference category.

6. Check the Enable Interference Type Trap check box to trigger interferer alarms when the Cisco WLC detects specified device types, or uncheck it to disable this feature. By default, this feature is in enabled state.

7. Ensure that any sources of interference that need to trigger interferer alarms appear in the Trap on These Types box and any that do not need to trigger interferer alarms appear in the Do Not Trap on These Types box. By default, all interference sources trigger interferer alarms.

   For example, if you want the Cisco WLC to send an alarm when it detects a jamming device, check the Enable Interference Type Trap check box and move the jamming device to the Trap on These Types box.

Click Apply.

Trigger spectrum event-driven radio resource management (RRM) to run when a Cisco CleanAir-enabled AP detects a significant level of interference as follows:

1. Look at the EDRRM field to see the current status of spectrum event-driven RRM and, if enabled, the Sensitivity Threshold field to see the threshold level at which event-driven RRM is invoked.

2. If you want to change the current status of event-driven RRM or the sensitivity level, click Change Settings. The 802.11a (or 802.11b) > RRM > Dynamic Channel Assignment (DCA) page is displayed.

3. Check the EDRRM check box to trigger RRM to run when an AP detects a certain level of interference, or uncheck it to disable this feature. By default, this feature is in enabled state.

4. If you checked the EDRRM check box in Step c, choose Low, Medium, High, or Custom from the Sensitivity Threshold drop-down list to specify the threshold at which you want RRM to be triggered. When the interference for the AP rises above the threshold level, RRM initiates a local dynamic channel assignment (DCA) run and changes the channel of the affected AP radio if possible to improve network performance. Low represents a decreased sensitivity to changes in the environment while High represents an increased sensitivity.

   If you selected the EDRRM sensitivity threshold as custom, you must set a threshold value in the Custom Sensitivity Threshold field. The default sensitivity is 35.

   The EDRRM AQ threshold value for low sensitivity is 35, medium sensitivity is 50, and high sensitivity is 60.

5. Save the configuration.

• UP—The spectrum sensor for the access point radio is currently operational (error code 0).
• DOWN—The spectrum sensor for the access point radio is currently not operational because an error has occurred. The most likely reason for the error is that the access point radio is disabled (error code 8). To correct this error, enable the radio.
• ERROR—The spectrum sensor for the access point radio has crashed (error code 128), making CleanAir monitoring nonoperational for this radio. If this error occurs, reboot the access point. If the error continues to appear, you might want to disable Cisco CleanAir functionality on the radio.
• N/A—This access point radio is not capable of supporting Cisco CleanAir functionality.
