Generating Interim Accounting Records

Enables a network access server (NAS) to send periodic accounting records about a subscriber's session at a predefined interval.

Throttling of AAA (RADIUS) Records

Offload Server Accounting Enhancement

Allows you to maintain authentication and accounting information between your network access server (NAS) and the offload server.

RADIUS Route Download

Allows you to configure your network access server (NAS) to direct RADIUS authorization.

RADIUS: Separate Retransmit Counter for Accounting

Allows you to configure an exponential backoff retransmit; that is, after the normally configured retransmission retries have been used, the router keeps on trying with an interval that doubles on each retransmission failure until a configured maximum interval is reached.

RADIUS Server Load Balancing

Distributes authentication, authorization, and accounting (AAA) transactions across servers in a server group.

RADIUS Server Reorder on Failure

Provides for failover to another server in the server group during periods of high load or when server failure occurs.

Vendor-Specific Attributes (VSA) and RADIUS Disconnect-Cause Attribute Values
