PTP configuration example (IEEE 1588 Version 2)
Network requirements
As shown in
Configure all devices to use PTP standard IEEE 1588 Version 2.
Configure the clock node type of Device A and Device C as OC, and that of Device B as P2PTC. All
clock nodes elect a GM through BMC based on their respective default GM attributes.
Configure the delay measurement mechanism for Device A and Device C as p2p.
