Network time protocol (NTP) service is essential to some of the more complex Address Manager functions, such as xHA and DHCP failover, and differential deployment.

Note: Address Manager 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 Address Manager server configuration. For information on configuring NTS, refer to the full topic in the Address Manager Administration Guide.

A specific external time reference is also essential to some organizations for reports and compliance tracking. The NTP services on Address Manager act as both a source of NTP synchronization for clients and as clients themselves to another NTP service that synchronizes the clock reference they provide.

To configure NTP on the Address Manager server:

  1. Select the Settings tab in the sidebar, then select Service configuration.
  2. Under Server management and configuration, locate the NTP service panel and select Edit service.
  3. On the General tab, ensure that Enabled is checked to enable the NTP service.
  4. On the NTP servers tab:
    • In the Server field, enter the fully-qualified domain name or IP address for a remote NTP server from which Address Manager or BDDS will reference the time.
    • In the Stratum drop-down menu, 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.
  5. Select the Add server to table button to associate a stratum value to a server and add them to the list. To remove a server, select the Remove (Trash icon) button. The top-most NTP server will be queried first, then the second, continuing down the list.
    Note: By default, the Address Manager NTP server list contains the following IP address:
    • The Local Reference Clock (127.127.1.0) on the connected server
  6. Select Save.
