Is authentication, authorization, and accounting (AAA) for RADIUS or TACACS+ supported on the FWSM?
A. AAA is supported for both FWSM management and traffic passing through the FWSM. Refer to the Firewall Services Module documentation for additional details. The FWSM offers similar functionality to that of the PIX Firewall, with the exceptions of downloadable access lists and VPNs. With this in mind, you can use these PIX Firewall documents as guides for FWSM configuration. • How To Perform Authentication and Enabling on the Cisco Secure PIX Firewall (5.2 Through 6.2) • Performing Authentication, Authorization, and Accounting of Users Through PIX Versions 5.
