Cisco Cisco IOS Software Release 12.2(27)SBC

The AAA Authorization and Authentication Cache feature allows you to cache authorization and 
authentication responses for a configured set of users or service profiles, providing performance 
improvements and an additional level of network reliability because user and service profiles that are 
returned from authorization and authentication responses can be queried from multiple sources and need 
not depend solely on an offload server. This feature also provides a failover mechanism so that if a 
network RADIUS or TACACS+ server is unable to provide authorization and authentication responses 
network users and administrators can still access the network.
