and synchronizes the time among multiple devices.
Switch C's local clock is to be used as a reference source, with the stratum level of 2.
•
• Switch C works in broadcast server mode and sends out broadcast messages from VLAN-interface 2.
• Switch A and Switch B work in broadcast client mode, and listen to broadcast messages through
their VLAN-interface 2 respectively.

Configuration procedure
Set the IP address for each interface as shown in
1.
Configuration on Switch C:
2.
# Configure Switch C to work in broadcast server mode and send broadcast messages through VLAN-
interface 2.
[SwitchC] interface vlan-interface 2
[SwitchC-Vlan-interface2] ntp-service broadcast-server
Configuration on Switch A:
3.
# Configure Switch A to work in broadcast client mode and receive broadcast messages on VLAN-
interface 2.
<SwitchA> system-view
[SwitchA] interface vlan-interface 2
[SwitchA-Vlan-interface2] ntp-service broadcast-client
Configuration on Switch B:
4.
# Configure Switch B to work in broadcast client mode and receive broadcast messages on VLAN-
interface 2.
<SwitchB> system-view
[SwitchB] interface vlan-interface 2
[SwitchB-Vlan-interface2] ntp-service broadcast-client
Switch A and Switch B get synchronized upon receiving a broadcast message from Switch C.
