For more information, see theĬonfiguration Guide for CISCO Secure ACS. The switch must have a RADIUS configuration and be connected to the Cisco secure access control server (ACS). For more information, see the documentation for your Cisco platform and theĬisco IOS Security Configuration Guide: Securing User Services. You should understand the concepts of the RADIUS protocol and have an understanding of how to create and apply access control lists (ACLs). The web authentication method is not supported on Cisco integrated services routers (ISRs) or Integrated Services Routers Generation 2 (ISR G2s) in Cisco IOS Release 15.2(2)T. If the authentication order includes web authentication, configure a fallback profile that enables web authentication on the switch and the interface. If the authentication order includes the 802.1X port authentication method, you must enable IEEE 802.1X authentication on the switch.

If appropriate, you must enable ACL download. The switch must be connected to a Cisco secure Access Control System (ACS) and RADIUS authentication, authorization, and accounting (AAA) must be configured for Web authentication. For more information, see theĬonfiguring IEEE 802.1X Port-Based Authentication module. You should understand the concepts of port-based network access control and have an understanding of how to configure port-based network access control on your Cisco platform.
