[SwitchA] interface vlan-interface 3 [SwitchA-Vlan-interface3] ntp-service ipv6 multicast-client ff24::1 7. Verify the configuration: # Display the NTP status of Switch A after clock synchronization. [SwitchA-Vlan-interface3] display ntp-service status Clock status: synchronized Clock stratum: 3 System peer: 3000::2 Local mode: bclient Reference clock ID: 165.84.121.65 Leap indicator: 00 Clock jitter: 0.165741 s Stability: 0.000 pps Clock precision: 2^-10 Root delay: 0.00534 ms Root dispersion: 4.51282 ms Reference time: d0c61289.10b1193f Wed, Dec 29 2010 20:03:21.065 The output shows that Switch A has been synchronized to Switch C, the clock stratum level of Switch A is 3, and that of Switch C is 2. # Display IPv6 NTP association information for Switch A. [SwitchA-Vlan-interface3] display ntp-service ipv6 sessions Notes: 1 source(master), 2 source(peer), 3 selected, 4 candidate, 5 configured. Source: [124]3000::2 Reference: 127.127.1.0 Reachabilities: 2 Last receive time: 71 Roundtrip delay: 0.0 Clock stratum: 2 Poll interval: 64 Offset: -0.0 Dispersion: 0.0 Total sessions : 1 The output shows that an association has been set up between Switch A and Switch C. Configuration example for NTP client/server mode with authentication Network requirements • As shown in Figure 15, configure the local clock of Device A as a reference source, with the stratum level 2. • Configure Device B to operate in client mode and specify Device A as the NTP server of Device B, with Device B as the client. • Configure NTP authentication on both Device A and Device B. 42
