Preparing The Ptp Configuration - Hirschmann RS20 User Manual

Synchronizing the System Time in the
Network
Independently of the physical communication paths, the PTP provides logical
communication paths which you define by setting up PTP subdomains.
Subdomains are used to form groups of clocks that are time-independent
from the rest of the domain. Typically, the clocks in a group use the same
communication paths as other clocks.

Preparing the PTP Configuration

After the function is activated, the PTP takes over the configuration
automatically. The delivery settings of the device are sufficient for most
applications.
To get an overview of the time distribution, draw a network plan with all
the devices participating in PTP.
