This MIB is intended to be implemented on all Cisco network entities that provide Wireless Domain Services (WDS). The WDS provides a control mechanism for wireless devices that roam between Access Points residing on different layer 3 subnets. When WDS is in the Wireless LAN Services Module(WLSM), the access points providing Layer 3 mobility must register with the WDS before wireless devices are given access to the mobility network. The location of the WDS is specified in each Access Point along with LEAP device credentials that are required for authentication with the WDS. Once the Access Point and the Mobile Node are authenticated with the WDS, those are considered registered. This MIB reports the information about the Wireless Domain Servers, Access Points, Mobile Nodes, and their roaming patterns. GLOSSARY AAA Authentication, Authorization, Accounting Access Point (AP) An entity that contains an 802.11 medium access control (MAC) and physical layer (PHY) interface and provides access to the distribution services via the wireless medium for associated devices. BSSID Basic Service Set Identification, where the basic service set is defined as the set of data transfer rates that all the stations in a BSS will be capable of using to receive frames from the wireless medium. CCKM Cisco Central Key Management. Context The mobility context for a Mobile Node includes its current mobility bindings with the Access Points, IP/802 address bindings, cached configuration parameters, QoS state, IP group membership, authentication state, accounting statistics, and other dynamically derived protocol state information. EAP Extensible Authentication Protocol. Hot Standby Router Protocol (HSRP) Cisco Hot Standby Router Protocol as defined in RFC2281 L3MM Layer-3 Mobility Manager (L3MM) is a new software entity residing on Central Switch (CS). L3MM maintains the mobility database and manages mGRE tunnels and tunnel paths to provide L3 Mobility for wireless clients. Layer 3 Mobility Control Protocol (LCP) A simple protocol to exchange control message between WDS and L3MM to achieve layer 3 seamless mobility for wireless devices. mGRE Tunnels Multipoint Generic Routing Encapsulation tunnels. This tunnel is used to tunnel wireless traffic and used to transfer wireless traffic between AP and CS. MIC Message Integrity Check. A MIC can, optionally, be added to WEP-encrypted 802.11 frames. Mobile Node (MN) A roaming 802.11 wireless device in a wireless network associated with an Access Point. SSID Service Set Identification, where the station service is defined as the set of services that support transport of medium access control (MAC) service data units (MSDUs) between stations within a basic service set. TKIP WPA Temporal Key encryption. Wireless Domain Services (WDS) The set of services being offered at a particular broadcast domain that may be an IP subnet or a particular VLAN, or across the L3 cloud. The services include the following. 1. Fast Secure Roaming with CCKM. 2. Layer 3 seamless mobility. 3. Radio Management aggregation for 802.11 wireless clients . WDS Entity The logical entity that resides in an infrastructure node and offers WDS to the descendants of that infrastructure node in the wireless services hierarchy. WEP Wired Equivalent Privacy. This is generally used to refer to 802.11 legacy encryption. WLSM Wireless LAN Services Module Wireless Network Manager (WNM) The network management system that manages the entire hierarchy of devices providing WDS. WPA WiFi Protected Access.
