Displaying And Maintaining Ntp; Ntp Client/Server Mode Configuration Example - H3C SR6600-X Configuration Manual

Make sure the local clock can provide the time accuracy required for the network. After you
•
configure the local clock as a reference source, the local clock is synchronized, and can operate as
a time server to synchronize other devices in the network. If the local clock is incorrect, timing errors
occur.
• Before you configure this feature, adjust the local system time to make sure it is accurate.
If the factory-default system time of the device always restores at a reboot, do not configure the local
•
clock as a reference source or configure the device as a time server.
To configure the local clock as a reference source:
Step
1. Enter system view.
2. Configure the local clock as a
reference source.
