Figure 13 Network diagram Vlan-int3 Vlan-int3 1.0.1.11/24 1.0.1.10/24 Vlan-int2 3.0.1.30/24 Switch A NTP multicast client Switch B Vlan-int2 3.0.1.31/24 Switch C NTP multicast server Vlan-int2 3.0.1.32/24 Switch D NTP multicast client Configuration procedure 1. Set the IP address for each interface as shown in Figure 13. (Details not shown.) 2. Configure Switch C: # Enable the NTP service. system-view [SwitchC] ntp-service enable # Specify the local clock as the reference source, with the stratum level 2. [SwitchC] ntp-service refclock-master 2 # Configure Switch C to operate in multicast server mode and send multicast messages through VLAN-interface 2. [SwitchC] interface vlan-interface 2 [SwitchC-Vlan-interface2] ntp-service multicast-server 3. Configure Switch D: # Enable the NTP service. system-view [SwitchD] ntp-service enable # Configure Switch D to operate in multicast client mode and receive multicast messages on VLAN-interface 2. [SwitchD] interface vlan-interface 2 [SwitchD-Vlan-interface2] ntp-service multicast-client 4. Verify the configuration: # Because Switch D and Switch C are on the same subnet, Switch D can receive the multicast messages from Switch C without being enabled with the multicast functions and can be synchronized to Switch C. Display the NTP status of Switch D after clock synchronization. [SwitchD-Vlan-interface2] display ntp-service status Clock status: synchronized Clock stratum: 3 System peer: 3.0.1.31 Local mode: bclient Reference clock ID: 3.0.1.31 37
