Device Analytics

Information About 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

  • From 17.1.1 release onwards, this feature is applicable to Samsung devices.

Note

Apple clients such as iPhones and iPads use 802.11k action frames to send device information to the controller. When they fail to send 802.11k action frames, the controller will not perform device classification based on the 802.11 protocol. Hence, this falls back to legacy device classification which is based on HTTP and DHCP protocols.

Restrictions for Device Analytics

  • 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.

Configuring Device Analytics (GUI)

Procedure

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.

Configuring Device Analytics (CLI)

Procedure

  Command or Action Purpose

Step 1

configure terminal

Example:

Device# configure terminal

Enters global configuration mode.

Step 2

wlan wlan-name wlan-id SSID-name

Example:

Device(config)# wlan device_analytics 1 device_analytics

Enters the WLAN configuration sub-mode.

  • wlan-name —Enter the profile name. The range is from 1 to 32 alphanumeric characters.

  • wlan-id —Enter the WLAN ID. The range is from 1 to 512.

  • SSID-name —Enter the Service Set Identifier (SSID) for this WLAN. If the SSID is not specified, the WLAN profile name is set as the SSID.

Note

 

If you have already configured WLAN, enter wlan wlan-name command.

Step 3

client association limit {clients-per-wlan | apclients-per-ap-per-wlan | radio clients-per-ap-radio-per-wlan}

Example:

Device(config)# client association limit 1 1

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:

Device(config)# device-analytics

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:

Device(config)# device-analytics export

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:

Device(config)# no shutdown

Enables the WLAN.

Step 7

end

Example:

Device(config)# end

Returns to privileged EXEC mode.

Verifying Device Analytics Configuration

To view the status of device analytics export, use the following command:

Device# show wlan 1 test-wlan

WLAN Profile Name     : test-wlan
================================================
Identifier                      : 1

Adaptive 802.11r

Information About 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.

Configuring Adaptive 802.11r (GUI)

Procedure

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.

Verifying Adaptive 802.11r

To view the details, use the following command:

Device# show running-config all 
wlan test-psk 2 test-psk
 security ft adaptive
"adaptive" is  optional

Note

The following command is used to enable or disable adaptive 11r:

[no] security ft adaptive

The following command is used to enable or disable 802.11r:

[no] security ft
