Configuring NTP on Address Manager - BlueCat Integrity - 9.3.0

Address Manager Administration Guide

Product name
BlueCat Integrity

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.

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 Administration tab. Tabs remember the page you last worked on, so select the tab again to ensure you're on the Administration page.
  2. Under General, click Service Configuration.
  3. From the Service Type drop-down menu, select Network Time Protocol (NTP).
  4. Under General Settings, set the following parameters:
    • Enable NTP Service—select this check box to enable the NTP service; deselect this check box to disable the NTP service.
    • NTP Server—enter the fully-qualified domain name or IP address for a remote NTP server from which Address Manager or BDDS 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 NTP 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. Click Add to associate a stratum value to a server and add them to the list. To remove a server, select it from the list and click Remove. The top-most NTP server will be queried first, then the second, and continues down the list. To change the order of servers in the list, select a server in the list and click Move up or Move down.
    Note: By default, the NTP Server list contains at least the following IP addresses:
    • DNS/DHCP ServerNTP list:
      • the IP address for the Address Manager appliance managing the DNS/DHCP Server
    • Address Manager NTP list:
      • the Local Reference Clock ( on the connected server.
  6. Click Update.
