To ensure that authentication, authorization and accounting (AAA) is performed correctly, it is vital that the server maintains the correct time of day at all times. It is strongly recommended that you configure one or more NTP servers to automatically synchronize the server's time. NTP can interfere with timekeeping in virtual machines. The default virtual machine configuration will automatically synchronize its time with the host server, and 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. If available, it is recommended that you use an NTP server that is available on your local network. This will improve timekeeping and will eliminate the need for additional Internet traffic for the time server. 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. Click the Save and Continue button to apply the server's time configuration and continue with setup. Configure Default RADIUS NAS Vendor Type If your deployment uses only one type of NAS, click the NAS Type drop-down list and select the default NAS vendor type to use when defining RADIUS clients or creating RADIUS Web Login pages that have vendor-specific settings. Click the Save and Continue button to apply the RADIUS server configuration, or click Skip to Network Access Server List to continue with setup. Amigopod 3.7 | Deployment Guide Setup Guide | 41
