Netflow is a protocol for collecting IP traffic information
from network devices for traffic monitoring. 
The netflow architecture consists of:
   -Collector: An entity that collects all the IP traffic 
               info from various network elements
   -Exporter: A network entity that exports the template 
              of the information that will be exported along 
              with the actual data which maps to the exported 
              template. WLC will play the role of an Exporter.
        
          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 to.
        
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
controllers.
        
Mobile Node ( MN )
        
A roaming 802.11 wireless device in a wireless
network associated with an access point.
