II. NTP peer configuration example
1) Network requirements
On Quidway3, set local clock as the NTP master clock at stratum 2. On Quidway2,
configure Quidway1 as the time server in server mode and set the local equipment as in
client mode. At the same time, Quidway5 sets Quidway4 as its peer.
2) Networking diagram
See Figure 7-2.
3) Configuration procedure
Configure Ethernet Switch Quidway3:
# Enter system view.
<Quidway3> system-view
# Set the local clock as the NTP master clock at stratum 2.
[Quidway3] ntp-service refclock-master 2
Configure Ethernet Switch Quidway4:
# Enter system view.
<Quidway4> system-view
# Set Quidway1 as the NTP server at stratum 3 after synchronization.
[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:
[Quidway4] display ntp-service status
