Can anyone help e troubleshoot a Cisco LWAPP issue?
I have a collection of Cisco WLC4404s on my network and I have groups of CIsco LWAPP access points associated with them ranging from 4 - 42 depending on the controller. I am seeing the access points "drop off" the network from time to time and in some areas it is happening every few minutes. The access points lose connectivity with the controller, fail and when they reboot they associate with the correct controller again and the cycle starts all over again. From the controllers log and cli I get no useful information but from the access point console I get errors indicating that the Ethernet que is overloaded and the ap cannot forward any more traffic out of the interface. I imagine this is why the AP stops talking to the controller but I am trying to figure out what is causing this to happen. I am fairly new to wireless networking and could use any assistance available. If there is a better group to post to for this type of issue please let me know.
Has anyone seen this before? Does anyone have a solution? Can someone provide a link or some help with troubleshooting the wireless side of this as I suspect it could be malicious clients int he area but I am not sure how to isolate that. Additionally this issue is happening in geographically disperse areas and the code on the controllers is not the same but the issue happens regardless.
