Device A

Device B

 

 

Perform the following configurations on Device B. 

# View the NTP status of Device B before synchronization. 

<DeviceB> display ntp-service status 

 Clock status: unsynchronized 

 Clock stratum: 16 

 Reference clock ID: none 

 Nominal frequency: 60.0002 Hz 

 Actual frequency: 60.0002 Hz 

 Clock precision: 2^18 

 Clock offset: 0.0000 ms 

 Root delay: 0.00 ms 

 Root dispersion: 0.00 ms 

 Peer dispersion: 0.00 ms 

 Reference time: 00:00:00.000 UTC Jan 1 1900 (00000000.00000000) 

# Set Device A as the NTP server of Device B. 

<DeviceB> system-view 

[DeviceB] ntp-service unicast-server 1.0.1.11 

# (After the above configurations, Device B is synchronized to Device A.) View the NTP status of Device 

B. 

[DeviceB] display ntp-service status 

 Clock status: synchronized 

 Clock stratum: 3 

 Reference clock ID: 1.0.1.11 

 Nominal frequency: 60.0002 Hz 

 Actual frequency: 60.0002 Hz 

 Clock precision: 2^18 

 Clock offset: 0.66 ms 

 Root delay: 27.47 ms 

 Root dispersion: 208.39 ms 

 Peer dispersion: 9.63 ms 

 Reference time: 17:03:32.022 UTC Thu Sep 7 2006 (BF422AE4.05AEA86C) 

The above output information indicates that Device B is synchronized to Device A, and the stratum level 

of its clock is 3, one level lower than that of Device A. 

# View the information about NTP sessions of Device B. (You can see that Device B establishes a 

connection with Device A.)
