NTP configuration examples
249BConfiguring NTP client/server mode
In this example, Device A is the Firewall.
424BNetwork requirements
Perform the following configurations to synchronize the time between Device B and Device A:
• As shown in
839HFigure 52, the local clock of Device A is to be used as a reference source, with the
stratum level 2.
• Device B operates in client/server mode and Device A is to be used as the NTP server of Device B.

425BConfiguration procedure
1. Set the IP address for each interface as shown in 840HFigure 52. (Details not shown.)
2. Configure Device A:
# Specify the local clock as the reference source, with the stratum level 2.
<DeviceA> system-view
[DeviceA] ntp-service refclock-master 2
3. Configure Device B:
# Display the NTP status of Device B before clock synchronization.
<DeviceB> display ntp-service status
Clock status: unsynchronized
Clock stratum: 16
Reference clock ID: none
Nominal frequency: 64.0000 Hz
Actual frequency: 64.0000 Hz
Clock precision: 2^7
Clock offset: 0.0000 ms
Root delay: 0.00 ms

Reference time: 00:00:00.000 UTC Jan 1 1900 (00000000.00000000)
# Specify Device A as the NTP server of Device B so that Device B synchronizes to Device A.
<DeviceB> system-view
[DeviceB] ntp-service unicast-server 1.0.1.11
# Display the NTP status of Device B after clock synchronization.
[DeviceB] display ntp-service status
