7.2.2 Preparing the SNTP Configuration
 To get an overview of how the time is passed on, draw a network plan with
all the devices participating in SNTP. When planning, bear in mind that
the accuracy of the time depends on the signal runtime.
Figure 26: Example of SNTP cascade
 Enable the SNTP function on all devices whose time you want to set using
SNTP.
The SNTP server of the device responds to Unicast requests as soon as
it is enabled.
 If no reference clock is available, specify a device as the reference clock
and set its system time as accurately as possible.
Note: For accurate system time distribution with cascaded SNTP servers
and clients, use only network components (routers, switches, hubs) in the
signal path between the SNTP server and the SNTP client which forward
SNTP packets with a minimized delay.
