NTP client/server mode configuration example

Configuration procedure
1. Set the IP address for each interface as shown in Figure 29 . (Details not shown.)
2. Configure Device A:
# Enable the NTP service.
system-view
[DeviceA] ntp-service enable
# Specify the local clock as the reference source, with the stratum level 2.
[DeviceA] ntp-service refclock-master 2
3. Configure Device B:
# Enable the NTP service.
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:
# Display the NTP status of Device B after clock synchronization.
[DeviceB] display ntp-service status
Clock status: synchronized
Clock stratum: 3
System peer: 1.0.1.11
