CISCO-LWAPP-SI-MIB: View SNMP OID List / Download MIB

This MIB module defines objects that describes the configuration and status of the spectrum intelligence capabilities of the 802.11 Access points. 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. The relationship between CC and the LWAPP APs can be depicted as follows: +......+ +......+ +......+ +......+ + + + + + + + + + CC + + CC + + CC + + CC + + + + + + + + + +......+ +......+ +......+ +......+ .. . . . .. . . . . . . . . . . . . . . . . . . . . . . . +......+ +......+ +......+ +......+ +......+ + + + + + + + + + + + AP + + AP + + AP + + AP + + AP + + + + + + + + + + + +......+ +......+ +......+ +......+ +......+ . . . . . . . . . . . . . . . . . . . . . . . . +......+ +......+ +......+ +......+ +......+ + + + + + + + + + + + MN + + MN + + MN + + MN + + MN + + + + + + + + + + + +......+ +......+ +......+ +......+ +......+ 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. 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'. 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. Spectrum Intelligence (SI) Radio frequency (RF) interference from devices operating in the unlicensed 2.4-GHz and 5-GHz bands used by wireless LANs (WLANs) is a growing concern for organizations deploying indoor and outdoor wireless networks. A variety of RF devices are now available that can cause interference, including cordless phones, Bluetooth devices, cameras, paging systems, unauthorized access points, and clients in ad-hoc mode. Left unaddressed, RF interference can result in low data rates and throughput, lack of sufficient WLAN coverage, WLAN performance degradation, poor voice quality, and low end-user satisfaction. This, in turn, can lead to decreased network capacity, an increase in support calls, network downtime, rising operational costs, and potential security vulnerabilities from malicious interference. Spectrum Intelligence, industry-leading solution from Cisco detects, classifies, and locates devices causing RF interference in the unlicensed 2.4-GHz and 5-GHz bands. When the source of the interference is determined, customers can remove, move, shield, adjust, or replace the interference source. This helps organizations troubleshoot the wireless network to determine the root causes of interference problems and optimize network performance. Sensord The Sensord software looks at the timing and frequency of interference bursts, and the discovered attributes of the bursts such as the modulation type and identified sync words. This high-level information is then used to perform the final identification and separation of one device from another. This final classification step provides the powerful features of SI: Identifying the specific source of the interference, where it is located, and how it can be mitigated. Persistent Device Propagation Interference devices usually affect multiple wireless access points. Using persistent device propagation information regarding persistent interference devices can be passed from one access point to another access point effectively improving radio resource management. Radio Resource Management ( RRM ) RRM is the system level control of co-channel interference and other radio transmission characteristics in wireless communication systems.
