This MIB provides information about WLAN roaming configuration. GLOSSARY IEEE 802.11 Standard to encourage interoperability among wireless networking equipment. Access point (AP) Transmitter/receiver (transceiver) device that commonly connects and transports data between a wireless network and a wired network. Access control (AC) To control and manage multi-APs, it will bridge wireless and wired network. BSS IEEE 802.11 Basic Service Set (Radio Cell). The BSS of an AP comprises of the stations directly associating with the AP. Radio The chip set to receive and send wireless signal. HA The AC to which a wireless station is connected by associating with an AP for the first time is the HA of the station. FA An AC that is other than the HA and to which a station is currently connected is an FA of the station. Fast-roam capable station A wireless station which directly associates to a fast-roam service (rsn+dot1X) with one AC for the first time. Roam-out station A wireless station which has associated with an AC other than the HA in the mobility-group is referred to as a roam-out station at its HA. Roam-in station A wireless station which has associated with an AC other than the HA in the mobility-group is referred to as a roam-in station at the FA. Intra-AC roaming A procedure where a wireless station roams from one AP to another AP, which are connected to the same AC. Inter-AC roaming A procedure where a wireless station roams from one AP to another AP, which are connected to different ACs. Inter-AC fast roaming capability If a station uses 802.1x (RSN) authentication through negotiation, this station has inter-AC fast roaming capability. WLAN-tunnel One type of layer 2 interface which is bound with an IACTP data tunnel and used to tunnel unicast/broadcast frames between ACs.
