PTP configuration example (IEEE 802.1AS)

Network requirements
As shown in
Configure all devices to use PTP standard IEEE 802.1AS.
•
Configure the clock node type as OC for Device A and Device C, and P2PTC for Device B. 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 802.1AS.
<DeviceA> system-view
[DeviceA] ptp profile 802.1AS
# Specify the clock node type as OC.
[DeviceA] ptp mode oc
# Specify the system time source as PTP.
[DeviceA] clock protocol ptp
# Enable PTP on GigabitEthernet 2/0/1.
[DeviceA] interface gigabitethernet 2/0/1
[DeviceA-GigabitEthernet2/0/1] ptp enable
[DeviceA-GigabitEthernet2/0/1] quit
2. Configure Device B:
