The NTP Synchronization Interval on the Switch
The maximum NTP synchronization interval on the switch is 210 seconds. The interval for clock synchronization between the NTP client and server is not fixed and depends on the clock precision. A higher clock precision results in a longer synchronization interval. The synchronization interval depends on the following factors:
Time difference between the client and server
Frequency offset of the clock on the client compared with the clock on the server.
