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.
