As shown in
•
Configure the local clock of Device A as a reference source, with stratum level 2.
•
Configure Device B to operate in client mode and Device A to be used as the NTP server for
Device B.

1.0.1.11/24
Device A
Configuration procedure
1. Assign an IP address to each interface, and make sure Device A and Device B can reach each
other, as shown in
2. Configure Device A:
# Enable the NTP service.
<DeviceA> system-view
[DeviceA] ntp-service enable
# Specify the local clock as the reference source, with stratum level 2.
[DeviceA] ntp-service refclock-master 2
3. Configure Device B:
# Enable the NTP service.
<DeviceB> system-view
[DeviceB] ntp-service enable
# Specify Device A as the NTP server of Device B so that Device B is synchronized to Device A.
[DeviceB] ntp-service unicast-server 1.0.1.11
4. Verify the configuration:
# Verify that Device B has synchronized to Device A, and the clock stratum level is 3 on Device
B and 2 on Device A.
