I wonder if somebody is able to help or advise with a query. I have a number of 2820 routers at different sites which I am able to connect to and monitor. Also a number of AP700's connected to these 2820's for wi-fi access.

Now what I want do is instead of having to constantly monitor these routers so as no rogue devices (iphones, ipads, home laptops, etc) are connected is have some kind of alert system to alert me when of theses rogue devices is connected.

At the moment I monitor the MAC address of devices/NIC to ascertain whether its a company machine or something else. Is there an app, software or something I can use to store rogue MAC OUI's that I don't want on the network so it alerts me when one is connected and I can block it.

If anybody can help this would make lifew a hell of a lot easier instead of having to physical go through each routers ARP table checking MAC addresses.
