17.6.5.2.2. Boundary Clock

The boundary clock typically has several physical ports communicating with the network. The messages related to synchronization, master-slave hierarchy, and signaling terminate in the protocol engine of the boundary clock and are not forwarded. The PTP message type status given by the MAC helps you to identify the type of message and take appropriate action. The boundary clock is similar to the ordinary clock except for the following features:

  • The clock data sets are common to all ports of the boundary clock .
  • The local clock is common to all ports of the boundary clock. Therefore, the features of the ordinary clock are also applicable to the boundary clock.
