7.3.2 Preparing the PTP configuration

After the function is activated, the PTP takes over the configuration automat-
ically. The delivery settings of the Switch are sufficient for most applications.
To get an overview of the time distribution, draw a network plan with all
the devices participating in PTP.
Note: Connect all the connections you need to distribute the PTP information
to connections with an integrated time stamp unit (RT modules).
Devices without a time stamp unit take the information from the PTP and use
it to set their clocks. They are not involved in the protocol.
