We have 3 WLANs that I'm planning on reducing to 1, all are WPA2-PSK. I'm going to keep our voice WLAN since it has the most clients by far and enable MAC authentication on it, we're using ACS5.7 to do the MAC authentication.
I've now enabled MAC authentication on the voice WLAN on one of our smaller sites but I've come across an issue. In the last 24 hours I've seen over 200,000 MAC auth attempts but only around 0.3% of these are legit (there are only 6 handsets on that site).
Other than sending an access deny response from ACS (which is what it's doing) is there a way of dealing with this that would reduce the huge number or repeated authentication failures?
Thanks
