heterogeneous systems that include clocks of various inherent precision, resolution and stability to synchronize to a

grandmaster clock.

The synchronization is divided into two processes. The Best Master Clock (BMC) algorithm determines the PTP status

(master/slave) of all local ports. The synchronization algorithm computes the clock offset between the master and

slave clock. There are two mechanisms, Delay Request-response Mechanism and Peer Delay Mechanism, for

measuring the propagation time of an event message.

The PTP system has three types of PTP devices, boundary clock, end-to-end transparent clock, and peer-to-peer

transparent clock. Only the boundary clock can participate in the selection of the best master clock.

When the stacking mode is enabled and the member ports of a trunk group exists in different stack units, the PTP

function will:
