This MIB module defines managed objects that facilitate
the management of policies upon host(s) admission to 
a network. 
        
The information available through this MIB includes:
        
o Statistics information such as number of total and
  active sessions. 
        
o Session information such as IP and MAC address of
  host, client type, and session state.
        
o QoS and Security policy applied to host traffic upon 
  host admission to a network. 
        
The following terms are used throughout this MIB:
        
QoS (Quality of Service) is the method which attempts 
to ensure that the network requirements of different 
applications can be met by giving preferential forwarding
treatment to some traffic.
        
ACL (Access Control List) which contains filters used
to identify traffic flows with certain characteristics.
        
Downloadable ACL is a set of filters, configured on the 
RADIUS server which are downloaded during authorization 
phase of admission features like dot1x, authProxy, etc.
        
SGT (Security Group Tag) is a unique 16 bits value assigned
to every security group and used by network devices to
enforce network policies. 
        
URL: Universal Resource Locator.
        
URL-Redirect ACL is used for URL redirection feature. Any 
ingress HTTP from the host that matches the ACL content 
is subjected to redirection to the URL address specified by 
the URL-Redirect string.
        
URL redirect string is the URL to which HTTP traffic to 
the host would be redirected.
