7.3.2 Preparing the PTP configuration
After the function is activated, the PTP takes over the configuration
automatically. The original settings in the Switch when it is delivered
are
sufficient for most applications.
V Draw a network plan showing all devices involved in PTP to get an
overview of the distribution of the clocks.
Note: Connect all connections you need to distribute PTP information to
devices equipped with an integrated time stamp unit (RT modules).
Devices which are not equipped with a time stamp unit obtain the PTP infor-
