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 devices. If you need to accurately display the time on network devices that are connected to a CPE device, you can use such a device as an NTP server.

You can specify the NTP server in a CPE template or on the device. When you specify an NTP server in a CPE template, this server is automatically specified on all devices that are using the 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 an NTP server in a CPE template, go to the SD-WAN → CPE templates menu section, click the template and in the displayed settings area, 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 device, and in the displayed settings area, 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 pool of servers:
   1. Under NTP servers, click + Add.
   2. In the field that is displayed, 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; to delete a server, click the delete icon next to it.

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

You can view the time synchronization settings on the CPE device by requesting diagnostic information.
