I. Network requirements
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-interface 2.
Device A and Device D are two S5600 Ethernet switches. Configure Device A and
Device D to work in the NTP broadcast client mode and listen to broadcast
messages through their own VLAN-interface 2.
