PTP configuration example (IEEE 1588 Version 2)
Network requirements
As shown in Figure 22 , a PTP domain comprises Device A, Device B, and Device C.
• 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.

Configuration procedure
1. Configure Device A:
# Specify the PTP standard as IEEE 1588 Version 2.
system-view
[DeviceA] ptp profile 1588v2
# Specify the clock node type as OC.
[DeviceA] ptp mode oc
# On Ten-GigabitEthernet 1/0/1, specify the delay measurement mechanism as p2p, and enable
PTP.
[DeviceA] interface ten-gigabitethernet 1/0/1
[DeviceA-Ten-GigabitEthernet1/0/1] ptp delay-mechanism p2p
[DeviceA-Ten-GigabitEthernet1/0/1] ptp enable
[DeviceA-Ten-GigabitEthernet1/0/1] quit
2. Configure Device B:
# Specify the PTP standard as IEEE 1588 Version 2.
system-view
[DeviceB] ptp profile 1588v2
# Specify the clock node type as P2PTC.
[DeviceB] ptp mode p2ptc
# Enable PTP for Ten-GigabitEthernet 1/0/1.
[DeviceB] interface ten-gigabitethernet 1/0/1
[DeviceB-Ten-GigabitEthernet1/0/1] ptp enable
[DeviceB-Ten-GigabitEthernet1/0/1] quit
# Enable PTP for Ten-GigabitEthernet 1/0/2.
[DeviceB] interface ten-gigabitethernet 1/0/2
[DeviceB-Ten-GigabitEthernet1/0/2] ptp enable
