Abort Reason:DOT1X RESTARTED DUE TO EAPOL-START/CLIENT ROAM

collrbbrt — Wed, 06 Mar 2024 20:32:40 GMT

I see a lot of these errors on my Cisco 5500 Series Wireless LAN Controller, Software, Version 8.5.151.0. Is this something I should worry about? what would be the fix?

I would not worry about it unless users facing an issue. Message indicating client has to re-authenticate due to moving away from the current AP.

AireOS controllers typically do sticky key caching (SKC) and it is normal to do full authentication every time clients goes to a new AP.

Yes, if he use any Fast Roaming (CCKM or FT) then full authentication not required when client roaming. Since it is 5508 with 8.5.x deployment, i would not expect FT to be enabled.

I'm facing a few users complaining of intermittent Wi-Fi connection. when I look in Prime I see they either joined another AP or rejoined the Same AP. I was wondering if that error is related to what the users are facing.

Yes FT is Disabled.
