APs reboot due to high number of clients per radio

[Dieter Prinesdoma]

Hi,

Has anyone problems with accesspoints reboots at high client count (50+ associations per radio)

We have a 5508 WLC with 7.3 Code and 3600 AP´s.

Our problem is that sometimes accesspoints reboots. And this only if a lot of clients are connected.

Many thanks in advance for your help

Yes it is possible that the access points will reboot. There could be a couple different reasons why, most noticeable would be interference caused by so many clients (clients themselves can cause co-channel interference). Is the AP actually rebooting or is the radios resetting due to some reason?

50 clients???  Per RADIO????

Seriously?

I don´t know the reason why the ap reboot. This is the problem. We monitor the Ap with nagios and we see that the ap is offine for a few minutes. So I believe the ap reboot.

We found no logs on the wlc for the reason.

The problem area is a congress center a so sometimes we have really a lot of users. (like a Cisco Networkers)

We have all the typical problems at high density WLAN. (a lot of Rouge Ap´s, high channel  utilization, interference …)

But could that the reason why a accesspoint reboot?

Take a look at the ap uptime and the ap join, that will tell you if the ap has rebooted and or if it lost connection with the WLC.

Thanks,

Scott

Ok, look for a crash dump in the controller.  Management > Tech Support > AP Crash Log.

If there is NONE, then try the following commands:

1.  debug ap enable ;

2.  debug ap command "sh version"; and

3.  debug ap disable

Post the output.

As what Scott has mentioned, there are alot of reason why a WAP reboots without any intervention and faulty cabling could also be the culprit.
