Clients dropping periodically - WLC5508

I've noticed a handful of clients (Apple TV devices) that are constantly associating and disassociating with some of my APs. They do this 24hrs whether there are other clients or not on the same AP so I don't think it is a congestion issue. I see the following on the 5508 controller log:

When I move the AP to another controller the problem goes away. We are using MAC based auth for these devices. Where can I look to find out why these clients are having what looks like authentication issues?

That's a hard one, and this is going to sound like it's from deep left field.....

But I'd check the traffic between the AP and the original WLC.  Things like the path, what VLAN are trunked to the WLC etc.  What are the differneces between the WLC connection to the LAN wise.

Steve,

I'll check the settings as this is a new controller and it is in a different building than my other two controllers. No other devices on this WLAN are affected though - just the Apple TV boxes.

And this happening to ONLY Apple clients?  Other type of clients (Androids, Windows, Linux) are fine?

What firmware is your 5500 running?

Clients dropping periodically - WLC5508

leolaohoo,

5508 is running 7.2.110.0

This is only happening to Apple TV devices. All other Apple clients (iPads, iPhones, laptops, etc) as well as our Windows clients are fine.

It seems to be the combination of this particular controller with all of my Apple TV devices.

AppleTV + 5508 = Problem

AnyOtherDevice + 5508 = Works fine

AppleTV + WiSM(6509) = Works fine

The WiSM controllers are running 7.0.235.0 so I might try rolling back to that on the 5508 and seeing if that makes a difference. I'm guessing it is a difference in configs between the 5508 and WiSM that is causing an issue with the way these devices connect to the network. Not sure where to look for any logging or clues though.

Thanks,

-mike

I have Apple TV's running on that code on 5508's with no issues.  If you have double checked everything and the configs are the same, then maybe try to downgrade and see if that helps.

Thanks,

Scott

Michael,

What mode are your APs in? Local or FlexConnect?

Have you actually wittnessed an Apple TV disconnecting or do you just no longer see them as an available device on an iPad for example?

Thanks,

Aaron

Hi Guy's and Gal's

I have a problem like Michael does... just a tad different. My AppleTV's are updated to the latest code and my iPads are up to 6.1.3 code. I have a single 5508 running 7.2.110 and Multicasting is working when the AppleTV's stay connected.

The controller sends a "deauth" message and kicks the device off and then is being added to the "Excluded" list.

and its over and over. every 3 to 5 minutes or less in some cases. Then the TV will reconnect and work.

If seen this happen in the past with other non-apple devices as well if "client load balancing" is enabled on the WLAN.

But, this is only happening to the AppleTV devices. I've also disabled "session timeout" as a test and see no difference.

I've searched up and down on the INTERWEB about this and get nothing..

I'm debating upgrading the controller to 7.4 with Bonjour mDNS as an option but, this is an obvious L1 issue!!

Any idea's from the experts?

Hi

Have you considered increasing the User idle timeout on the Controller tab menu?

Hi all,

I am having the same problem only with iphone devices.

The WLC is 2504 model with 7.3.112.0 software version.

The access points are in flexconnect mode.

The following debug output is generated for one of the iphone devices:

Clients dropping periodically - WLC5508

HI Scott,

My client user idle timeout is 300 Seconds which is default.

What do you suggest?

Highlighted

It depends on what is the issue.  For Apple clients and guest webauth, I would set the idle timer to 2 hours or 4 hours depending.  This prevents the clients that go in sleep mode to not have to login again.

Thanks,

Scott

Clients dropping periodically - WLC5508

code 7.4 has a client user idle timeout setting under each WLAN on the advanced tab.  the default is set to 300s.  i'm assuming this takes precendence over the user idle timeout setting on the controller tab.

Does anybody know what happens if you set the client idle timeout setting under the WLAN to 0?  will it use the user idle timeout setting on the controller tab?

You can't set the idle timer to 0.

Client user idle timeout(15-100000)

Thanks,


Scott
