Applying Policy Using the RADIUS Response Attributes

If an authentication method that requires communication with an authentication server is configured for a user, the RADIUS filter-ID attribute can be used to dynamically assign a policy role to the authenticating user. Supported RADIUS attributes are sent to the switch in the RADIUS access-accept message. The RADIUS filter-ID can also be applied in hybrid authentication mode. Hybrid authentication mode determines how the RADIUS filter-ID and the three RFC 3580 VLAN tunnel attributes (VLAN Authorization), when either or all are included in the RADIUS access-accept message, will be handled by the switch. The three VLAN tunnel attributes define the base VLAN-ID to be applied to the user. In either case, conflict resolution between RADIUS attributes is provided by the maptable response feature.
