Hello,
We saw some wireless disconnections randomly on a MAC client
The debug logs points to this
Sep 20 10:55:50.826 | *osapiBsnTimer | 4-Way PTK Handshake, Client did not respond with M5 |
Sep 20 10:55:50.826 | *Dot1x_NW_MsgTask_3 | 4-Way PTK Handshake, Retransmitting M5 retry #1 |
Sep 20 10:55:51.826 | *osapiBsnTimer | 4-Way PTK Handshake, Client did not respond with M5 |
Sep 20 10:55:51.826 | *Dot1x_NW_MsgTask_3 | 4-Way PTK Handshake, Retransmitting M5 retry #2 |
Sep 20 10:55:52.826 | *osapiBsnTimer | 4-Way PTK Handshake, Client did not respond with M5 |
Sep 20 10:55:52.826 | *Dot1x_NW_MsgTask_3 | 4-Way PTK Handshake, Retransmitting M5 retry #3 |
Sep 20 10:55:53.826 | *osapiBsnTimer | 4-Way PTK Handshake, Client did not respond with M5 |
Sep 20 10:55:53.826 | *Dot1x_NW_MsgTask_3 | 4-Way PTK Handshake, Retransmitting M5 retry #4 |
Sep 20 10:55:54.826 | *osapiBsnTimer | 4-Way PTK Handshake, Client did not respond with M5 |
Sep 20 10:55:54.826 | *Dot1x_NW_MsgTask_3 | Client has been deauthenticated |
Sep 20 10:55:54.826 | *Dot1x_NW_MsgTask_3 | Client expiration timer code set for 10 seconds. The reason: Roaming failed due to WLAN security policy mismatch between controllers (configuration error). It can also be used to report EAPoL retry errors, and GTK rotation failure (in 8.5) |
Sep 20 10:56:04.826 | *apfReceiveTask | Client session has timed out |
Sep 20 10:56:04.826 | *apfReceiveTask | Client expiration timer code set for 10 seconds. The reason: Client was marked for deletion, and it was on associated, power save or blacklist state. Other message would provide reason for delete |
Sep 20 10:56:14.826 | *apfReceiveTask | Client has been deauthenticated |
Sep 20 10:56:14.826 | *apfReceiveTask | Client session has timed out |
Sep 20 10:56:14.826 | *apfReceiveTask | Client expiration timer code set for 10 seconds. The reason: Client has timedout during authentication at local controller, it is marked as idle, and deleted after timer expires. Possible client bouncing between Aps during authentication |

I'm sorry to ask this, disabling FT would it really help as 802.1k was created for MAC books for a faster roaming experience.
The debug logs shows some mismatch in Security exchange, would that be related to FT?
Thanks

Hello George,
Does these problems occurs in what kind of devices?
I had exact this problem with iPhones endpoints, and i fixed with reboot WLC.
