boundary-clock – A boundary clock can have multiple network
connections and can accurately bridge synchronization from one
network segment to another.
disable – Disables PTP on the switch.
transparent-clock – A transparent clock modifies PTP messages
as they pass through the switch, updating the time stamps to
correct for time spent traversing the network.
end-to-end – This method measures the residence time
required for PTP event messages to cross from the input port to
