b
Enter VLAN interface 2 view.
[S4200G]

[S4200G-Vlan-interface2]
c

b
Enter VLAN interface 2 view.

[S4200G-Vlan-interface2]
c
Configure S4200G 1 to be a broadcast client.

3
Configure S4200G 2
a
Enter system view.
<S4200G>
system-view
System View: return to User View with Ctrl+Z.
[S4200G]
b
Enter VLAN interface 2 view.
[S4200G]
interface vlan-interface 2
[S4200G-Vlan-Interface2]
c
Configure S4200G 2 to be a broadcast client.
[S4200G-Vlan-interface2]
ntp-service broadcast-client
The above configuration configures S4200G 1 to listen to broadcast packets through
their VLAN interface 2, and S4200G 3 to send broadcast packets through VLAN
interface 2. Because S4200G 2 does reside in the same network segment as S4200G
3 resides, the former cannot receive broadcast packets sent by S4200G 3, while
S4200G 1 is synchronized to S4200G 3 after receiving broadcast packets sent by
S4200G 3.
Display the status of S4200G 1 after the synchronization.
