Wireless Access

I am getting walkups reporting that people are dropping off of wireless, and when I go into airwave I see that the client count has dropped by 50%. There are 5 SSIDs being serviced, all of which are connected to vlans with no wired ports. The client count usually comes back with no intervention on my part. Where can I look to see why this is happening?

 

Thanks,

Can you pick a client that you know if dropping and turn up some logging? Also, this seems like a major issue so you should open a TAC case in parallel.

 

logging level debugging user-debug <mac-address>

 

logging level debugging arm-user-debug <mac address>

 

alright, what do I look for in the logs?

 

Thanks,

Make sure your APs are not bootstrapping
Show ap debug counters , look for high bootstrapping numbers

Check your connection from the controller to your Uplink switch and confirm that there's a lot of errors

Does it happen at certain times of day when there's a lot of users ?

You have a lot SSIDs on your environment , you may want to turn on drop multicast / broadcast

What version of AOS you have installed and type APs ?

what are high bootstrap numbers? I see double digits in half of my APs, single in the other half. Nothing over 32. No errors on the uplink. APs are all 135s. multicast/broadcast dropping is turned on on all SSIDs.
