Precision Time Protocol (PTP) management messages are general PTP messages sent to PTP-enabled switches on the data plane. On a8ÓéÀÖ switches, its behavior depends on the configured PTP mode. In Boundary Clock mode, they are handled by the control plane. In Transparent Clock mode, they are forwarded in the data plane. PTP management messages can be sent through the PTP network either in a multicast or unicast fashion (by using?ptp forward unicast, see?Forwarding Unicast PTP Packets in Boundary Mode).
