Before you configure NTP service on a DNS/DHCP Server, you must first add the DNS/DHCP Server under Address Manager control. For more information, refer to the Adding DNS/DHCP Servers to Address Manager section of the Address Manager Administration Guide.

Note: DNS/DHCP Server v26.1.0 introduces support for the Network Time Security (NTS) extension for NTP. NTS extends NTP with cryptographic authentication, ensuring time synchronization is trusted, accurate, and tamper-proof. This topic contains NTP setup instructions for basic DNS/DHCP Server configuration. For information on configuring NTS, refer to the full topic in the Address Manager Administration Guide.

To configure NTP on a DNS/DHCP Server appliance:

  1. Select the Servers tab in the sidebar, then select Servers.
  2. Select the name of a server.
  3. Select the Services tab.
  4. Under Server management and configuration, locate the NTP service panel and select Edit service.
  5. On the General tab, set the following parameters:
    • Enabled—select this check box to enable the NTP service; deselect this check box to disable the NTP service.
  6. On the NTP servers tab, set the following parameters:
    • Server—enter the fully-qualified domain name or IP address for a remote NTP server from which Address Manager or DNS/DHCP Server will reference the time.
    • Stratum—select a stratum value for the NTP server being added. This value will be associated to an individual NTP server specified in the Server field. Select Default to use the stratum value set on the remote NTP server.
    Note: Stratum values indicate the hierarchy level for the NTP server, which is the number of servers to a reference clock. This is used by the NTP client to avoid synchronization loops by preferring servers with a lower stratum.
  7. Select Add server to table to associate a stratum value to a server and add them to the list. The top-most NTP server will be queried first, then the second, and continues down the list.
    By default, the DNS/DHCP Server NTP servers list contains the following IP address:
    • DNS/DHCP Server NTP list:
      • The IP address for the Address Manager appliance managing the DNS/DHCP Server
  8. Select Save.
