Configuring NTP association mode
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.
