Precision Time Protocol Precision Time Protocol (PTP, IEEE 1588) is a protocol that enables precise synchronization of clocks with a sub-microsecond accuracy across a packet-based network. PTP lets network devices of different precision and resolution synchronize to a grandmaster clock through an exchange of packets across the network. The switch supports a PTP end-to-end transparent clock, which is enabled by default, both globally and at the port level. Note: The switch itself is not affected by PTP. Manage the global PTP settings By default, PTP is enabled globally on the switch. You can disable PTP to globally, in which case the switch does not support PTP pass-through.
