CISCO-LWAPP-DHCP-MIB
AI MIB Summary
The CISCO-LWAPP-DHCP-MIB provides management access to DHCP-related configuration and status parameters for Cisco Central Controllers terminating LWAPP tunnels from lightweight Access Points. It enables monitoring of the DHCP provisioning state and association data required for Mobile Nodes connecting through the LWAPP architecture.
This MIB is used to manage Dynamic Host Configuration Protocol (DHCP) related information on the devices operating as Central controllers, that terminate the Light Weight Access Point Protocol tunnel from Cisco Light-weight LWAPP Access Points.
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 them to the controller to which it is logically connected.
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. Mobile Node, Mobile Station(Ms) and client are used interchangeably.
