Технические ссылки для Cisco Cisco 4404 Wireless LAN Controller

The Cisco Unified Wireless Network architecture is illustrated in 

The architecture centralizes wireless LAN configuration and control on the controller. This allows the 
wireless LAN to operate as an intelligent information network and support advanced services, unlike the 
traditional 802.11 wireless LAN infrastructure that is built from autonomous, discrete entities. The Cisco 
Unified Wireless Network architecture simplifies operational management by collapsing large numbers 
of managed endpoints and autonomous access points into a single managed system of wireless LAN 
controller(s).

In this Cisco Unified Wireless Network architecture, access points are "lightweight," meaning that they 
cannot act independently of a controller. The wireless LAN controller manages the access point 
configurations and firmware. The access points are zero-touch and no individual configuration of access 
points is required. The access points handle only real-time MAC functionality, leaving all the 
non-real-time MAC functionality to be processed by the wireless LAN controller. This is referred to as 
the Split MAC architecture. 

As you can see in 

, access points interact with the controller via LWAPP. LWAPP defines the 

following: 

Control messaging protocol and format

Data encapsulation
