Clients deauthenticating - ReasonCode: 108

Hello,

 

We've been having some issues with multiple devices that are being deauthenticated with ReasonCode: 108. The devices either auth using certificates, or PEAP username and pass, and on either type of authentication the WLC has log entries throwing ReasonCode: 108:

From what I could gather, the devices actually remain associated to the SSID, have an IP address, but stop responding to ping.

 

The APs are AIR-AP2802E-E-K9, they're connected to Cisco 3504 WLCs, and broadcast two SSIDs (main WLAN on 5GHz only, and a guest WLAN). The security policies that are applied on the main SSID (the one that we're having issues with) are [WPA2][Auth(802.1X + CCKM)].

 

Has anyone had this issue before, or know what this reason code points to? I tried searching the web for additional info about it, but I haven't had too much luck...

 

Thank you.

All the same type of clients? Then it could be a driver issue.

Which software version is running on the WLC?

Based on the latest logs, most clients that have this issue are Apple devices, but there are some instances of a Huawei phone, a Xiaomi phone, and an Intel NIC that have this problem as well. Haven't seen this pop-up on laptops or other Android phones for now...

 

The WLC software version is 8.5.161.0 .

Then it might be some 802.11r issue. Do you have FT enabled on the SSID?




No, FT is disabled on the SSID.

Then I'm sadly out of ideas and suggest opening a TAC with Cisco.

Most likely this is a bug, you can open a TAC case to identify it or you can try to upgrade to 8.5.171.0 released a few days ago (best if you can upgrade to 8.10.142.0 after checking the compatibility matrix https://www.cisco.com/c/en/us/td/docs/wireless/compatibility/matrix/compatibility-matrix.html)

Thank you for your replies. I'll open a TAC case.
