Figure 6-57. RADIUS Server Configuration The RADIUS Server Configuration page contains the following fields: • RADIUS Server Host Address - Use the drop-down menu to select the IP address of the RADIUS server to view or configure. Click Add to display the Add RADIUS Server page used to configure additional RADIUS servers. • Port - Identifies the authentication port the server uses to verify the RADIUS server authentication. The port is a UDP port, and the valid range is 1-65535. The default port for RADIUS authentication is 1812. • Secret - Shared secret text string used for authenticating and encrypting all RADIUS communications between the device and the RADIUS server. This secret must match the RADIUS encryption. • Apply - The Secret will only be applied if this box is checked. If the box is not checked, anything entered in the Secret field will have no affect and will not be retained. This field is only displayed if the user has READWRITE access. • Primary Server - Sets the selected server to the Primary (Enable) or Secondary (Disable) server. If you configure multiple RADIUS servers with the same RADIUS Server Name, designate one server as the primary and the other(s) as the backup server(s). The switch attempts to use the primary server first, and if the primary server does not respond, the switch attempts to use one of the backup servers with the same RADIUS Server Name. 174 Configuring System Information
