NTP broadcast mode configuration example
Network requirements
As shown in Figure 13, Switch C functions as the NTP server for multiple devices on a network
segment and synchronizes the time among multiple devices.
• Configure Switch C's local clock as a reference source, with the stratum level 2.
• Configure Switch C to operate in broadcast server mode and send out broadcast messages
from VLAN-interface 2.
• Configure Switch A and Switch B to operate in broadcast client mode, and listen to broadcast
messages through VLAN-interface 2.

Configuration procedure
1. Set the IP address for each interface, and make sure Switch A, Switch B, and Switch C can
reach each other, as shown in Figure 13. (Details not shown.)
2. Configure Switch C:
# Enable the NTP service.
