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
# Enter Vlan-interface2 view.
[Quidway3] interface vlan-interface 2
# Set it as broadcast server .
[Quidway3-Vlan-Interface2] ntp-service broadcast-server
Configure Ethernet Switch Quidway4:
# Enter system view.
<Quidway4> system-view
# Enter Vlan-interface2 view.
[Quidway4] interface vlan-interface 2
[Quidway4-Vlan-Interface2] ntp-service broadcast-client
Configure Ethernet Switch Quidway1:
# Enter system view.
<Quidway1> system-view
# Enter Vlan-interface2 view.
[Quidway1] interface vlan-interface 2
[Quidway1-Vlan-Interface2] ntp-service broadcast-client
The above examples configured Quidway4 and Quidway1 to listen to the broadcast via
Vlan-interface2, Quidway3 to broadcast packets from Vlan-interface2. Since Quidway1
and Quidway3 are not located on the same segment, they cannot receive any
broadcast packets from Quidway3, while Quidway4 is synchronized by Quidway3 after
receiving its broadcast packet.
After the synchronization, you can find the state of Quidway4 as follows:
[Quidway4] display ntp-service status
clock status: synchronized
