2. Configure Device B:
# Specify the PTP standard as IEEE 802.1AS.
<DeviceB> system-view
[DeviceB] ptp profile 802.1AS
# 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
[DeviceB-Ten-GigabitEthernet1/0/2] quit
3. Configure Device C:
# Specify the PTP standard as IEEE 1588 802.1AS.
<DeviceC> system-view
[DeviceC] ptp profile 802.1AS
# Specify the clock node type as OC.
[DeviceC] ptp mode oc
# Enable PTP on Ten-GigabitEthernet 1/0/1.
[DeviceC] interface ten-gigabitethernet 1/0/1
[DeviceC-Ten-GigabitEthernet1/0/1] ptp enable
[DeviceC-Ten-GigabitEthernet1/0/1] quit
4. Verify the configuration:
When the network is stable, display PTP clock information by using the display ptp clock command,
and display brief PTP statistics on an interface by using the display ptp interface brief command.
# Display PTP clock information on Device A.
