Configuring NTP
You can enable or disable NTP on your system; when NTP is active the local clock is
synchronized as configured and hosts will be able to set their time through this machine.
To set the time manually, see “Setting the System Time” on page 158.
To configure NTP
1. Click NTP under Configuration > Router Services in the tree view.
2. Click Yes in the Enable NTP field.
3. Click Apply.
The NTP configuration page appears.
4. Enter the new server IP address in the Add New Server Address edit box.
5. Click Apply.
The IP address for the new NTP server appears in the NTP Servers field. By default, this
new server is enabled, v3 is selected, and Prefer Yes is selected. As you add other servers,
you might prefer them over the initial server you configured.
Note
Nokia recommends that you use the default setting of v3.
6. To add another new server, repeat step 4 and click Apply.
7. (Optional) Enable the NTP reference clock by clicking Yes in the NTP Master field and

defaults.

box.

them over the initial peer you configured.
