Specifying NTP servers on CPE devices

You must specify an internal or external NTP server, or a pool of servers for CPE devices to make sure accurate time is displayed on these CPE devices. You can use a CPE device as an NTP server to display exact time on network devices that are connected to the CPE device.

You can specify the NTP server in a CPE template or on the CPE device. NTP servers specified in the CPE template are automatically specified on all CPE devices that use this CPE template.

To specify the NTP server on CPE devices:

  1. Specify the NTP server in one of the following ways:
    • If you want to specify the NTP server in a CPE template, go to the SD-WAN → CPE templates section, click the CPE template, and select the NTP tab.
    • If you want to specify an NTP server on a CPE device, go to the SD-WAN → CPE menu section, click the CPE device, and select the NTP tab and select the Override check box.

    The NTP server connection settings are displayed.

  2. If you do not want to specify the NTP server for the CPE device, clear the Connect to NTP server check box. This check box is selected by default.
  3. If you want to use the CPE device as an NTP server, select the Use CPE as NTP server check box. This check box is cleared by default.
  4. Specify an NTP server or a pool of servers:
    1. Under NTP servers, click + Add.
    2. In the displayed field, enter the IP address or FQDN of the NTP server or pool of servers. The following IP address and FQDN formats are supported:
      • To specify an NTP server, enter the IP address or FQDN in the server <IP address or FQDN> format, for example, server 0.pool.ntp.org.
      • To specify a pool of NTP servers, enter the IP address or FQDN in the pool <IP address or FQDN> format, for example, pool pool.ntp.org.

    The NTP server is specified and displayed in the NTP servers section. You can specify multiple NTP servers or delete a NTP server. To delete an NTP server, click the delete icon cross_icon_3 next to it.

  5. In the upper part of the settings area, click Save to save the settings of the CPE template or CPE device.

You can request diagnostic information to view the time synchronization settings on a CPE device.
