Cisco Wireless - Client DeAuthentication issue. Unspecified ReasonCode1

[SOcchiogrosso]

I have a WLC 2125 with 1252 LWAPPs.

In the recent traps of the WLC I get loads of DeAuth messages. If I do not clear the traps it can exceed a few hundred entries after a couple hour period.

I can not find anything on Reason Code1

Example Error:

Client Deauthenticated: MACAddress: MAC ADDRESS Base Radio  MAC: MAC ADDRESS Slot: 0 User Name: unknown Ip Address: IP Address  Reason:Unspecified ReasonCode: 1

Any common issue/resolution with this I can not seem to find?

I have the same issue? any luck getting this resolved- we have 802.1x backend auth. The user successfully authenticates, but then is deauthenticated as in your message. I thought there might be a DHCP issue but the server is working for other scopes.

I believe my issue was caused by MFP, Management Frame Protection, most of my clients were not CCXv5 compliant at the time.

I disabled MFP on the controller, AP's, and WLAN..
