Table 12: Settings for the example
In the example, the left device, as an SNTP client, gets the time from the
NTP server via SNTP. The device assigns clock stratum "2" to the time
received from an NTP server. Thus the left device becomes the reference
clock for the PTP synchronization. PTP is active for all three devices, thus
providing precise time synchronization between them. As the connectable
terminal devices in the example only support SNTP, all three devices act
as SNTP servers.
