RADIUS/Policy/NetLogin
 
 
  RADIUS/Policy/NetLogin mappings are not persistent.
  Actions when RADIUS is enabled::
    - Policy maptable may be configured to use policy, tunnel, or both. 
- RADIUS may return a policy name, a VLAN, and possibly an Network Service
          Identifier (NSI) mapping.If RADIUS returns a VLAN/NSI mapping: 
              - Policy is not enabled:
                policy does not install an NSI mapping.
- Policy is enabled: the
                mapping is installed if the following conditions are met.
                  - Policy must be configured to make use of the RADIUS
                    (RFC3580) VLAN, meaning:
                      - The Policy maptable response must be set to “tunnel”
                        or “both”.
- If the response is set to “policy” (the default), the
                        VLAN/NSI is not used.
 
- The VLAN and NSI must both be specified for the NSI to be
                    used (see Defining VLAN/NSI Mappings with RADIUS Standards Attributes or VSAs).
- The authentication response is an initial authentication
                    for the given user or a re-authentication of an existing user with a mapping
                    that differs from the existing mapping.
