LAN Interface dropping Packetes

Unanswered Question
Apr 1st, 2009

I have two Aironet 1232 and both of them have started dropping packets today. When I ping thier IP I am losing at 50% of the packets. They are able to keep a stable wireless connection with their clients but the clients are unable to access the LAN.

I just found it odd that two access points would have the same problem on the same day. I'm monitoring my network for unusual traffic but have not found any.

I also set one of them back to factory default but I continue to have problems with the LAN side of it.

Is any one aware of a virus that could be causing this? Am I being Hacked?

I have this problem too.

From the WLC, can you do "sh ap eventlog ", what are the results?

What's the CPU level of each accesspoint?

CPU Usage very High - What do you think is happening?

CPU utilization for five seconds: 96%/95%; one minute: 96%; five minutes: 95%

PID Runtime(ms) Invoked uSecs

What's the result when you do a "sh ap eventlog "?

When you consoled into the AP, do a "dir" and see if you can find any crashinfo or r0.core file.

What is the firmware you are running on your controller?

I did not find crashinfor or ro.core files.

I'm running verions 12.3

I assume that u talking about autonomous AP's?!

what is the VLAN configuration on these AP's?

Try to check if there are broadcast storms or network loops?

It turns out my DC was generating WINS traffic at a unusually high level. For what ever reason that was killing the APs processor. I simply rebooted the server and the issue was resolve.

Thank you for leading down the right path.
