Abstract
Traffic broadcast to a VLAN is restricted. To do so, a plurality of stations are associated with a BSSID (basic service set identifier). A first VLAN is configured by sending a first group key to each station from the plurality of stations that is a member of the first VLAN, wherein each VLAN is associated with a unique group key. One or more frames addressed to the first VLAN are received. The one or more frames are encrypted with the first group key to prevent stations without the first group key from being able to decrypt the one or more frames. The one or more encrypted VLAN frames are broadcast to the plurality of stations associated with the BSSID.
