How long is the NTP synchronization interval on an S series switch

5

The maximum NTP synchronization interval on an S series switch (except the S1700) is the tenth power of 2 in seconds, namely, 1024 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 two factors:
1. Time difference between the client and server
2. Frequency offset of the clock on the client compared with the clock on the server

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: 1.Time difference between the client and server 2.Frequency offset of the clock on the client compared with the clock on the server.

Configure NTP on S series switches
S series switches (except S1700 switches) use NTP to synchronize clocks in the following modes: unicast NTP server/client, peer, broadcast, multicast, and manycast. The following is an example of synchronizing clock of Switch B with that of Switch A in the unicast NTP server/client mode. # Set the local clock of Switch A as the NTP master clock, and set the clock stratum to 2. [SwitchA] ntp-service refclock-master 2 # On Switch B, specify Switch A as its NTP server. [SwitchB] ntp-service unicast-server 10.0.0.1

How S series switches select an NTP server
S series switches (except S1700 switches) select an NTP server as follows: Question: After an NTP server is configured for S1, S2 configures S1 and the NTP server as active/standby NTP servers and sets the priority of S1 to be higher than that of the NTP server. Which NTP server takes effect for S2? Answer: S1, as an NTP client, belongs to an NTP server. When both S1 and the NTP server are configured as the NTP servers for S2, the priority of S1 is lower than the priority of the NTP server regardless of the priority settings on S2. Therefore, the NTP server of S1 takes effect for S2. The NTP server priority settings only take effect for the NTP servers irrelevant to each other.
