The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Configuring Cisco CleanAir on the Controller
Step 1 | Configure Cisco CleanAir
functionality on the 802.11 network by entering this command:
config {802.11a | 802.11b} cleanair {enable | disable} all If you disable this feature, the Cisco WLC does not receive any spectrum data. The default value is enable. | ||
Step 2 | Enable CleanAir
on all associated access points in a network:
config {802.11a | 802.11b} cleanair enable network You can enable CleanAir on a 5-GHz radio of mesh access points. | ||
Step 3 | Configure interference
detection and specify sources of interference that need to be detected by the
Cisco CleanAir system by entering this command:
config {802.11a | 802.11b} cleanair device {enable | disable} type where you choose the type as one of the following:
| ||
Step 4 | Configure the
triggering of air quality alarms by entering this command:
config {802.11a | 802.11b} cleanair alarm air-quality {enable | disable} | ||
Step 5 | Specify the
threshold at which you want the air quality alarm to be triggered by entering
this command:
config {802.11a | 802.11b} cleanair alarm air-quality threshold threshold where threshold is a value between 1 and 100 (inclusive). 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. | ||
Step 6 | Enable the
triggering of interferer alarms by entering this command:
config
{802.11a |
802.11b}
cleanair alarm device {enable |
disable}
The default value is enable. | ||
Step 7 | Specify sources of interference that trigger alarms by entering this command: config {802.11a | 802.11b} cleanair alarm device type {enable | disable} where you choose the type as one of the following: | ||
Step 8 | Configure the
triggering of air quality alarms for unclassified devices by entering this
command:
config {802.11a | 802.11b} cleanair alarm unclassified {enable | disable} | ||
Step 9 | Specify the
threshold at which you want the air quality alarm to be triggered for
unclassified devices by entering this command:
config {802.11a | 802.11b} cleanair alarm unclassified threshold threshold where threshold is a value from 1 and 99 (inclusive). 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. | ||
Step 10 | Trigger spectrum
event-driven radio resource management (RRM) to run when a Cisco
CleanAir-enabled access point detects a significant level of interference by
entering these commands:
config advanced {802.11a | 802.11b} channel cleanair-event {enable | disable}—Enables or disables spectrum event-driven RRM. The default value is disabled. config advanced {802.11a | 802.11b} channel cleanair-event sensitivity {low | medium | high | custom}—Specifies the threshold at which you want RRM to be triggered. When the interference level for the access point rises above the threshold level, RRM initiates a local dynamic channel assignment (DCA) run and changes the channel of the affected access point radio if possible to improve network performance. Low represents a decreased sensitivity to changes in the environment while high represents an increased sensitivity. You can also set the sensitivity to a custom level of your choice. The default value is medium. config advanced {802.11a | 802.11b} channel cleanair-event sensitivity threshold thresholdvalue—If you set the threshold sensitivity as custom, you must set a custom threshold value. The default is 35. | ||
Step 11 | Configure and
monitor Interference Awareness by entering the following commands:
| ||
Step 12 | Enable
persistent devices propagation by entering this command:
config advanced {802.11a | 802.11b} channel pda-prop {enable | disable} | ||
Step 13 | Save your changes by entering this command: | ||
Step 14 | See the Cisco
CleanAir configuration for the 802.11a/n or 802.11b/g/n network by entering
this command:
show {802.11a | 802.11b} cleanair config Information similar to the following appears: (Cisco Controller) >show 802.11a cleanair config Clean Air Solution...............................

Configuring Cisco CleanAir on an Access Point
Step 1 | Choose Wireless > Access Points > Radios > 802.11a/n or 802.11b/g/n to open the 802.11a/n/ac (or 802.11b/g/n) Radios page. | ||
Step 2 | Hover your cursor over the blue drop-down arrow for the desired access point and click Configure. The 802.11a/n/ac (or 802.11b/g/n) Cisco APs > Configure page appears. The CleanAir Capable field shows whether this access point can support CleanAir functionality. If it can, go to the next step to enable or disable CleanAir for this access point. If the access point cannot support CleanAir functionality, you cannot enable CleanAir for this access point.
| ||
Step 3 | Enable Cisco CleanAir functionality for this access point by choosing Enable from the CleanAir Status drop-down list. To disable CleanAir functionality for this access point, choose Disable. The default value is Enable. This setting overrides the global CleanAir configuration for this access point. The Number of Spectrum Expert Connections text box shows the number of Spectrum Expert applications that are currently connected to the access point radio. Up to three active connections are possible. | ||
Step 4 | Click Apply. | ||
Step 5 | Click Save Configuration. | ||
Step 6 | Click Back to return to the 802.11a/n/ac (or 802.11b/g/n) Radios page. | ||
Step 7 | View the Cisco CleanAir status for each access point radio by looking at the CleanAir Status text box on the 802.11a/n/ac (or 802.11b/g/n) Radios page. The Cisco CleanAir status is one of the following:
|
Step 1 | Configure Cisco CleanAir functionality for a specific access point by entering this command: config {802.11a | 802.11b} cleanair {enable | disable}Cisco_AP | ||
Step 2 | Save your changes by entering this command: | ||
Step 3 | See the Cisco CleanAir configuration for a specific access point on the 802.11a/n/ac or 802.11b/g/n network by entering this command: show ap config {802.11a | 802.11b} Cisco_AP Information similar to the following appears: Cisco AP Identifier.............................. 0 Cisco AP Name.................................... CISCO_AP3500 ... Spectrum Management Information Spectrum Management Capable.............. Yes Spectrum Management Admin State.......... Enabled Spectrum Management Operation State......
