Boundary Clock Application
A Boundary Clock network element has several PTP ports, one configured
as Slave port and all others acting as Master ports.
The PETS can be synchronized to the timing information received at the
PTP slave port.

PTP Boundary Clock
For a Boundary Clock network element the XMC20 and the COGE5 have to
be configured as follows:
• COGE5, AP: /unit-x, Configuration - PTP - Clock Type:
− Boundary Clock.
• COGE5, AP: /unit-x/port-y, Configuration - PTP - PTP Mode:
− Ordinary/Boundary Clock.
• COGE5, AP: /unit-x/port-y, Configuration - PTP - Role:
− Slave (for ports with a fixed Slave role).
− Master (for ports with a fixed Master role).
− Master Or Slave (for ports for which the role can change when the
synchronization path direction changes).
• XMC20, AP: /ne, Configuration - PTP - PTP Mode:
− Frequency (only the PTP frequency information is evaluated).
− Frequency And Phase (the PTP frequency and phase information is
evaluated).
− Hybrid (the synchronous Ethernet frequency and the PTP phase infor-
mation are evaluated).
− Pure Hybrid (the synchronous Ethernet frequency and the PTP phase
information of the same clock source are evaluated).
