listening to multicast messages, and synchronizes its local clock based on the received multicast
messages.
In symmetric peers mode, broadcast mode, and multicast mode, the client (or the symmetric active peer)
and the server (the symmetric passive peer) can operate in the specified NTP operation mode only after
they exchange NTP messages with the Mode field 3 (client mode) and the Mode field 4 (server mode).
During this message exchange process, NTP clock synchronization can be implemented.

Configuring NTP operation modes
Devices can implement clock synchronization in one of the following modes:
Client/server mode—Configure only clients.
•
Symmetric mode—Configure only symmetric-active peers.
•
Broadcast mode—Configure both clients and servers.
•
• Multicast mode—Configure both clients and servers.

Configuring the client/server mode

For devices operating in client/server mode, make configurations on the clients.
If you specify the source interface for NTP messages by specifying the source interface source-interface
option, NTP uses the primary IP address of the specified interface as the source IP address of the NTP
messages.
A device can act as a server to synchronize other devices only after it is synchronized. If a server has a
stratum level higher than or equal to a client, the client will not synchronize to that server.
To specify an NTP server on the client:
