How do I enable 802.11k on Cisco 5508 running 8.0.120.0

[Bryce Stewart]

Hello,

I just upgraded a 5508 WLC to 8.0.120.0 and I have clients that are starting to have issues roaming from AP to AP using Apple / MAC devices.  How do I check to see if 802.11k is enabled on the controller and what would be the best practices to implement the protocol to help users. 

Things I think I know.....

I understand this is a protocol that is enabled globally per WLAN

You can only enable and disable this in CLI on most software versions.

Things I need to know.....

Do you have to enable the assisted roaming floor-bias too?

Do you have to enable the dual-band list as well?

Any help would be appreciated.

Thanks,

-Bryce

Here is the current best practice for AireOS controller. Enabling 802.11k is one of them as well.

Hello Rasika,

I would like to ask you for a specific question. It is better to use client load balancing or use Assisted roaming Prediction Optimization? Both cannot be enabled together.

Thank you

Listed below are the recommended WLC configuration commands for 802.11k using CLI. There is no GUI config for 802.11k:

• WLAN neighbor list Enable/Disable: This is to enable or disable the neighbor list from the WLC and also the RRM and Power Constraint Information Elements (IEs) on the APs.

config wlan assisted-roaming neighbor-list {enable|disable} wlanId

• WLAN neighbor list dual-band response Enable/Disable: This is to enable or disable the neighbor list including entries for both radio bands. Default is the band in which the client is currently associating.

config wlan assisted-roaming dual-list {enable|disable} wlanId

• Prediction list based assisted roaming Enable/Disable: This is to enable or disable the assisted roaming capabilities with a roaming optimization predict list. A warning will be printed out, and load-balancing will be disabled for the WLAN if load balancing is already enabled on the same WLAN.

config wlan assisted-roaming prediction {enable|disable} wlanId

You can find the list of Apple devices best practices in the the following document:
