Using multiple RADIUS server groups

The authentication and accounting features on the switch can use up to fifteen RADIUS servers and these servers can be put into groups. Up to 5 groups of 3 RADIUS servers each can be configured. The authentication and accounting features can choose which RADIUS server group to communicate with. End-user authentication methods (802.1X, MAC-based and web-based) can authenticate with different RADIUS servers from the management interface authentication methods (console, telnet, ssh, web).

Several commands are used to support the RADIUS server group option. The RADIUS server must be configured before it can be added to a group. See Configuring the switch for RADIUS authentication for more information.
