How Do I Configure the NTP Clock Source?

How Do I Configure the NTP Clock Source?

The NTP clock source provides the NTP clock service for the entire network. Devices on the network must synchronize the clock with the NTP clock source.

This section describes how to configure the NTP clock source on a CE switch that uses the unicast client/server mode as the NTP operating mode.

In unicast client/server mode, a CE switch functions as the NTP clock source after it is configured as the unicast server and its time is synchronized with an authoritative clock (GPS).

After the local clock of the CE switch is configured as the NTP clock source, other devices on the network synchronize time with the CE switch. Exercise caution when performing this configuration to prevent clock errors on network devices. It is recommended that a high-precision clock source (such as the GPS) be used if the user network requires high clock precision.

# Configure the NTP master clock, enable NTP authentication, and enable the NTP server function.
