Configuring NTP association modes
This section describes how to configure NTP association modes.

Configuring NTP in client/server mode

When the device operates in client/server mode, specify the IP address for the server on the client.
Follow these guidelines when you configure an NTP client:
• A server must be synchronized by other devices or use its local clock as a reference source before
synchronizing an NTP client. Otherwise, the client will not be synchronized to the NTP server.
If the stratum level of a server is higher than or equal to a client, the client will not synchronize to that
•
server.
You can configure multiple servers by repeating the ntp-service unicast-server and ntp-service ipv6
•
unicast-server commands.
