NTP
Introduction
Network Time Protocol (NTP) is used to synchronize system clocks among distributed time servers and clients on a network.
NTP uses stratums 1 to 15 to define clock accuracy. A lower stratum value represents higher accuracy.
If devices on a network cannot synchronize to an authoritative time source, you can perform the following tasks to achieve NTP synchronization on the network:
1. Select a device that has a relatively accurate clock on the network.
2. Configure the local clock of the device as its reference source.
3. Configure the device as a time server to synchronize other devices on the network.
You can configure a local clock as the reference source from the Web interface.
Restrictions and guidelines
Before configuring a local clock as the reference source, adjust the time on the local clock to ensure that it is accurate.
