enables device ecosystem partnerships for 802.11r functionality
allows information sharing between client devices and the controller and AP, and
is enabled by default when creating a WLAN.

Adaptive 802.11r functionality

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.

Configure adaptive 802.11r (GUI)

Configure adaptive 802.11r to enable fast roaming capabilities for wireless clients while maintaining backward compatibility with devices that do not support 802.11r.

Adaptive 802.11r allows wireless networks to automatically detect client capabilities and enable fast transition features when supported, providing seamless roaming without requiring separate WLAN configurations.

Procedure

	1.	Choose Configuration > Tags & Profiles > WLANs.
	2.	On the WLANs page, click the name of the WLAN.
	3.	In the Edit WLAN window, click the Security > Layer2 tab.
	4.	In the WPA Parameters section and Fast Transition drop-down list, choose Adaptive Enabled.
	5.	Click Update & Apply to Device.

The WLAN is configured with adaptive 802.11r, enabling automatic fast transition capabilities for compatible clients while maintaining connectivity for non-802.11r devices.

Adaptive 802.11r verification

Verify adaptive 802.11r configuration using command line interface.

To view the details, use this command:

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

Note

This command is used to enable or disable adaptive 11r:

[no] security ft adaptive

This command is used to enable or disable 802.11r:

[no] security ft
