Configure NTP Globally

You can use the following procedure to globally enable NTP.

You can also enable master mode on the NTP server configured on the switch. When the master mode is configured, peers can synchronize themselves with the local clock when the NTP server loses synchronization or if an external NTP source is not reachable.

Before you begin

You must globally disable NTP before you change the version.

Procedure

In the navigation pane, expand Configuration > Edit > NTP.
Select General.
Select the Globals tab.
Select Enable.
Enter a time interval.
Optional: To configure the switch as an NTP server, in the NTP Master section, select Enable.
In the Stratum field, enter a value.
Select Apply.
