PTP configuration examples
PTP configuration example (IEEE 1588 version 2)
Network requirements
As shown in Figure 21, 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.
<DeviceA> 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.
