DESCRIPTION
"This MIB is intended to be implemented on all those devices operating as Central Controllers (CC) that terminate the Light Weight Access Point Protocol tunnel from Light-weight LWAPP Access Points.
This MIB provides configuration and status information about the 802.11 Access Points that have joined the controller.
The relationship between CC and the LWAPP APs can be depicted as follows:

The LWAPP tunnel exists between the controller and the APs. The MNs communicate with the APs through the protocol defined by the 802.11 standard.
LWAPP APs, upon bootup, discover and join one of the controllers and the controller pushes the configuration, that includes the WLAN parameters, to the LWAPP APs.
The APs then encapsulate all the 802.11 frames from wireless clients inside LWAPP frames and forward the LWAPP frames to the controller.
GLOSSARY
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 clients. LWAPP APs encapsulate all the 802.11 frames in LWAPP frames and sends it to the controller to which it is logically connected.
Bluetooth Low Energy (BLE): Bluetooth Low Energy is a light-weight subset of classic bluetooth which is added in Hyper Action Location (HALO) enabled APs to make use of BLE beacons to communicate with wireless clients at short range.
Basic Service Set Identifier (BSSID): The identifier for the service set comprising of all the 802.11 stations under the control of one coordinating Access Point. This identifier happens to be the MAC address of the dot11 radio interface of the Access Point. The wireless clients that associate with the Access Point get the wired uplink through this particular dot11 interface.
Central Controller (CC): The central entity that terminates the LWAPP protocol tunnel from the LWAPP APs. Throughout this MIB, this entity also referred to as 'controller'.
Hyper Action Location (HALO): This is an external module for Cisco Access Points, which is responsible for high accuracy indoor location. It includes smart antenna and new software interfaces to enable high accuracy indoor location.
iBeacon: This is a low-cost transmitter which can transmit its own unique identification number to the local area.
Light Weight Access Point Protocol (LWAPP): This is a generic protocol that defines the communication between the Access Points and the Central Controller.
Mobile Node (MN): A roaming 802.11 wireless device in a wireless network associated with an access point.
Station Management (SMT): This term refers to the internal management of the 802.11 protocol operations by the AP to work cooperatively with the other APs and 802.11 devices in the network.
Link Latency: Latency is round trip time between AP and controller. There is a continuous heart-beat between AP and controller. AP calculates latency for each time and sends to controller.
AMSDU (Aggregate MAC Service Data Unit): A structure containing multiple MSDUs, transported within a single (unfragmented) or multiple (fragmented) Data MPDU.
Datagram Transport Layer Security (DTLS) protocol provides communications privacy for datagram protocols. The protocol allows client/server applications to communicate in a way that is designed to prevent eavesdropping, tampering, or message forgery.
Wireless Intrusion Prevention System (WIPS) is a network device that monitors the radio spectrum for the presence of unauthorized access points (intrusion detection), and can automatically take countermeasures (intrusion prevention).
SE (Spectrum Expert) is an application software, which when connected to Spectrum Intelligent Access Point, provides detailed RF spectrum plots and data, and assist in diagnosing network problems.
PPPOE (Point-to-Point Protocol Over Ethernet) provides a standard method to build sessions for transporting multi-protocol datagrams between point-to-point links over Ethernet.
OEAP (Office Extended Access Point) provides a method to extend their office network to outside the office premises like the employee homes, thereby providing a seamless experience to the employee irrespective of the location of the work. This solution should also support having private SSID whose data need to be switched at the AP itself.
EWC (Embedded Wireless Controller) on AP wireless network solution comprises of at least one 802.11ac Wave 2 Cisco Aironet Series access point (AP) with an in-built software-based wireless controller (WLC) managing other APs in the network. The AP acting as the WLC is referred to as the master AP while the other APs in the Cisco Embedded Wireless Controller network, which are managed by this master AP, are referred to as subordinate APs. In addition to acting as a WLC, the master AP also operates as an AP to serve clients along with the subordinate APs.
FIPS (Federal Information Processing Standards) are a set of standards that describe document processing, encryption algorithms and other information technology standards for use within non-military government agencies and by government contractors and vendors who work with the agencies.
Link aggregation (LAG) is a partial implementation of the 802.3ad port aggregation standard. It bundles all of the controller's distribution system ports into a single 802.3ad port channel. This reduces the number of IP addresses required to configure the ports on your controller. When LAG is enabled, the system dynamically manages port redundancy and load balances access points transparently to the user.
The Control And Provisioning of Wireless Access Points (CAPWAP) protocol is a standard, interoperable networking protocol that enables a central wireless LAN Access Controller (AC) to manage a collection of Wireless Termination Points (WTPs), more commonly known as Wireless Access Points.
Flexible Radio Assignment: The Flexible Radio Assignment feature allows either manual configuration of capable APs or for these APs to intelligently determine the operating role of the integrated radios based on the available RF environment. APs with flexible radio can automatically detect when a high number of devices are connected to a network and changes the dual radios in the access point from 2.4 GHz/5 GHz to 5 GHz/5 GHz to serve more clients. The AP performs this task while monitoring the network for security threats and RF Interference that may affect performance. Flexible Radio Assignment improves mobile user experience for high-density networks.
XOR Radio: XOR radio is a radio that can operate on both 2.4Ghz and 5Ghz bandwidth.
