To use a public NTP server, enter the following hostnames: 0.pool.ntp.org 1.pool.ntp.org 2.pool.ntp.org You can also use NTP pool servers located in your region. For more information, refer to the NTP Pool Project Web site: http://www.pool.ntp.org. NTP can interfere with timekeeping in virtual machines. The default virtual machine configuration will automatically synchronize its time with the host server, so you should not configure NTP within the virtual machine. However, make sure that the host is configured to keep its clock in sync with a suitable time source. 4. To enable automatic time synchronization with NTP, mark the check box in the NTP Service row. 5. Click Save and Continue to apply the server's time configuration and continue with setup. Configuring the Default RADIUS NAS Vendor Type If you do not need to configure the default NAS vendor type, click Skip to Network Access Server List to continue with setup. To configure the default Network Access Services (NAS) vendor type: 1. In the NAS Type drop-down list, if your deployment uses only one type of NAS, choose the default NAS vendor type to use when defining RADIUS clients or creating RADIUS Web Login pages that have vendor-specific settings. 2. Click Save and Continue to apply the RADIUS server configuration,. Defining RADIUS Network Access Servers A network access server (NAS) is a RADIUS client, and must be predefined in order to access the RADIUS server. For security, each NAS device must also have a shared secret which is known only to the device and the RADIUS server. Use the Network Access Servers list view to define the NAS devices for this server and to make changes to existing NAS devices. 44 | Setup Guide ClearPass Guest 3.9 | Deployment Guide
