Configuring NTP broadcast mode Network requirements • As shown in Figure 13, configure Switch C as a reference source, with the stratum level 2. • Configure Switch C to operate in broadcast server mode and send broadcast messages from VLAN-interface 2. • Configure Switch A and Switch B to operate in broadcast client mode, and listen to broadcast messages through their VLAN-interface 2 respectively. Figure 13 Network diagram Configuration procedure 1. Set the IP address for each interface as shown in Figure 13. (Details not shown.) 2. Configure Switch C: # Configure Switch C to operate in broadcast server mode and send broadcast messages through VLAN-interface 2. [SwitchC] interface vlan-interface 2 [SwitchC-Vlan-interface2] ntp-service broadcast-server 3. Configure Switch A: # Configure Switch A to operate in broadcast client mode and receive broadcast messages on VLAN-interface 2. system-view [SwitchA] interface vlan-interface 2 [SwitchA-Vlan-interface2] ntp-service broadcast-client 4. Configure Switch B: # Configure Switch B to operate in broadcast client mode and receive broadcast messages on VLAN-interface 2. 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. # Take Switch A as an example. Display the NTP status of Switch A after clock synchronization. [SwitchA-Vlan-interface2] display ntp-service status 25
