Security

Hello

Maybe this is the right place I am not sure but hopefully someone can help me. I have a Dell Aruba Controller with Clearpass setup. We are seeing several devices with bad authentications in clearpass. We want to block these mac addresses but we are looking to block them on he controller before they ever make it clearpass.Our SSIDs are not setup for MAC address filtering and we would prefer to leave them that way. Does anyone have any idea how this could be done? Thanks in advance.

(Aruba7640-US) #stm add-blacklist-client ?

<client-mac>            client to add to DoS list

Sorry I am very new to this. So i just run that on the controller itself to add this to the blacklist of the controller. At that point the controller will block the client from ever sending an authentication request to Clearpass?
