Configuring NTP Broadcast ModeNetwork requirementsz The local clock of Device C is set as the NTP master clock, with a stratum level of 2. ConfigureDevice C to work in the NTP broadcast server mode and send NTP broadcast messages throughVLAN-interface 2.z Device A and Device D are two S4500 Ethernet switches. Configure Device A and Device D towork in the NTP broadcast client mode and listen to broadcast messages through their ownVLAN-interface 2.Network diagramFigure 54-8 Network diagram for the NTP broadcast mode configurationConfiguration procedurez Configure Device C.# Enter system view. system-view# Set Device C as the broadcast server, which sends broadcast messages through VLAN-interface 2.[DeviceC] interface Vlan-interface 2[DeviceC-Vlan-interface2] ntp-service broadcast-serverz Configure Device A.
