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.

Device Analytics
The Device Analytics feature enhances the enterprise Wi-Fi experience for client devices to ensure seamless connectivity. This feature provides a set of data analytics tools for analysing wireless client device behaviour. With device profiling enabled on the controller, information is exchanged between the client device and the controller and AP. This data is encrypted using AES-256-CBC to ensure device security.
 Note |
|
This feature is applicable only for Cisco device ecosystem partners.
This feature is supported only on the 802.11ax and Wave 2 APs.
This feature is supported using central authentication in either local mode or Flexconnect mode.
| Step 1 |
Choose Configuration > Tags & Profiles > WLANs. |
| Step 2 |
On the WLANs page, click the name of the WLAN. |
| Step 3 |
In the Edit WLAN window, click the Advanced tab. |
| Step 4 |
In the Device Analytics section, select the Advertise Support check box. |
| Step 5 |
(Optional) In the Device Analytics section, select the Share Data with Client check box. |
| Step 6 |
Click Update & Apply to Device. |
| Command or Action | Purpose | |||
|---|---|---|---|---|
| Step 1 |
configure terminal Example: |
Enters global configuration mode. |
||
| Step 2 |
wlan wlan-name wlan-id SSID-name Example: |
Enters the WLAN configuration sub-mode.
|
||
| Step 3 |
client association limit {clients-per-wlan | apclients-per-ap-per-wlan | radio clients-per-ap-radio-per-wlan} Example: |
Sets the maximum number of clients, clients per AP, or clients per AP radio that can be configured on a WLAN. |
||
| Step 4 |
[no] device-analytics Example: |
This is enabled by default. Enables or disables device analytics. WLANs advertise analytics capability in beacons & probe responses. |
||
| Step 5 |
[no] device-analytics [export] Example: |
When export option is set, the information from Cisco devices are shared with compatible clients (such as, Samsung devices). Here, information from Cisco devices refer to the Cisco controller details, AP version, and model number. This configuration is disabled by default. |
||
| Step 6 |
no shutdown Example: |
Enables the WLAN. |
||
| Step 7 |
end Example: |
Returns to privileged EXEC mode. |

Adaptive 802.11r
The Cisco device ecosystem partner now supports 11r functionality on an adaptive 802.11r SSID. Samsung is one of the partners.
Note |
The Adaptive 802.11r is enabled by default. This means that when you create a WLAN, the adaptive 802.11r is configured by default. |
Client device information such as its model number, supported operating system is shared with the controller and AP while the device receives information such as controller and AP type, software release, etc. Also, this enables 802.11r-compatible devices to benefit from adaptive 802.11r on Cisco networks. This ecosystem comes handy especially for troubleshooting device disconnection from the AP as the controller receives information such as the disconnect reason code from the client device.
Note |
Devices without 11r support cannot join an SSID where 11r is enabled. To use the 11r functionality on devices, you need to create a separate SSID with 11r enabled and another with 11r disabled to support the non-11r devices in the network. Adaptive dot11r is supported by Apple iPad, Apple iPhone, and Samsung S10 devices. However; some software update creates a MIC mismatch error in these devices. But these errors are transient and clients will successfully be able to associate to the SSID in subsequent results. |
| Step 1 |
Choose Configuration > Tags & Profiles > WLANs. |
| Step 2 |
On the WLANs page, click the name of the WLAN. |
| Step 3 |
In the Edit WLAN window, click the Security > Layer2 tab. |
| Step 4 |
In the WPA Parameters section and Fast Transition drop-down list, choose Adaptive Enabled. |
| Step 5 |
Click Update & Apply to Device. |
