Excessive reauthentication from many connected clients

We are seeing where many clients reauthenticate many times per hour. Sometimes it is only three or four minutes and we see the client reauthenticationg again and again, in our radius logs. All this happens repeatedly with the client attached to the same AP and not even physically moving at all. We wre trying to understand what is triggering this reauthentication process over and over again for some clients. Needless to say the increased load on our radius server is a concern. Viewing the "show station-table" shows the clients have been logged on for only minutes. And for some clients they do not have this problem and they show being connected for many hours in the "show station-table" output.

Thanks,

Re: Excessive reauthentication from many connected clients

You should probably start by identifying what type of devices are doing that ?

You should pick one device and turn user-debug on for that particular MAC address

Also run the show auth-tracebuf

Have you made any recent changes under 802.1x profile ?



Thank you

Re: Excessive reauthentication from many connected clients

Thanks for the Reply.

Seems to affect all clients, and this may have been going on for over a year and was just now discovered.

We will see if the user-debug for a paticular device shows us anything.

The 802.1x profile has remained the same for years.

Controller has had code upgrades on a regular basis.

Thanks,

What AOS do you have installed ?

Re: Excessive reauthentication from many connected clients

We are running 6.3.1.1 on 7204 controllers.

But we do know this behavior existed on previous versions.

Re: Excessive reauthentication from many connected clients

I would choose a single client and enable debugging for that user to see what is going on. That is the best way to Attempt to narrow it down.

Re: Excessive reauthentication from many connected clients

We have exactly the same case. 

We are running also 6.3.1.1 but on 7210 controllers.

We got yesteday 164723 requests on clearpass with max of 1838 clients on airwave graphics.

I would then turn on debugging for one client with the issue and collect the logs.  http://community.arubanetworks.com/t5/Technology-Blog/Two-Different-Ways-to-Debug-a-User-on-Aruba-and-Why-You-Would/ba-p/77006

 

That would indicate who is initiating the authentication.

Re: Excessive reauthentication from many connected clients

Interesting facts with your debug procedure. I have two differents wireless device. One Laptop with windows 7 and one Ipod.

MAC address of Windows 7 is: 00:24:2C:08:DC:C1

MAC address of IPOD is: F0:CB:A1:B1:A7:2C

 

You can see output after this explain

 

I noticed IPOD make "station-down and station-up" and he make reauthentication each time. However, it is not not see this on a laptop with windows 7.

I haven't more time to made more troubleshooting on other device. But, Is it possible that we have a behavior problem on Apple side?
