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 synchronize 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.
