[Quidway4] ntp-service unicast-server 3.0.1.31
Configure Ethernet Switch Quidway5: (Quidway4 has been synchronized by
Quidway3)
# Enter system view.
<Quidway5> system-view
# Set the local clock as the NTP master clock at stratum 1.
[Quidway5] ntp-service refclock-master 1
# After performing local synchronization, set Quidway4 as a peer.
[Quidway5] ntp-service unicast-peer 3.0.1.32
The above examples configure Quidway4 and Quidway5 as peers and configure
Quidway5 as in active peer mode and Quidway4 in passive peer mode. Since
Quidway5 is at stratum 1 and Quidway4 is at stratum 3, synchronize Quidway4 by
Quidway5.
After synchronization, Quidway4 status is shown as follows:
