As shown in 

, the local clock of Device C is set as the NTP master clock, with a stratum 

level of 2. Configure Device C to work in the NTP broadcast server mode and send NTP broadcast 

messages through Vlan-interface2. 

z 

Device A and Device D are two WX3000 series devices. Configure Device A and Device D to work 

in the NTP broadcast client mode and listen to broadcast messages through their own 

Vlan-interface2.
