• Configure Device A to operate in symmetric-active mode and specify Device B as the passive peer
of 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 B:
# Enable the NTP service.
<DeviceB> system-view
[DeviceB] ntp-service enable
3. Configure Device A:
# Enable the NTP service.
<DeviceA> 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
# Configure Device B as a symmetric passive peer.
[DeviceA] ntp-service unicast-peer 3.0.1.32
4. Verify the configuration:
# Verify that Device B has synchronized to Device A.
[DeviceB] display ntp-service status
Clock status: synchronized
Clock stratum: 3
System peer: 3.0.1.31
Local mode: sym_passive
Reference clock ID: 3.0.1.31
