Figure 47 graphically represents a server group named "Radii" that consists of two RADIUS servers, Radius-1 and Radius-2. The server group is assigned to the server group for 802.1x authentication. Figure 47: Server Group Server names are unique. You can configure the same server in multiple server groups. You must configure the server before you can add it to a server group. NOTE: If you are using the controller's internal database for user authentication, use the predefined "Internal" server group. You can also include conditions for server-derived user roles or VLANs in the server group configuration. The server derivation rules apply to all servers in the group. Configuring Servers This section describes how to configure RADIUS, LDAP, TACACS+ and Windows external authentication servers and the internal database on the controller. Configuring a RADIUS Server Table 48 describes the parameters you configure for a RADIUS server. Table 48: RADIUS Server Configuration Parameters Parameter Host Description IP address or fully qualified domain name (FQDN) of the authentication server.
