Figure 15 Network diagram Configuration procedure 1. Set the IP address for each interface as shown in Figure 15. (Details not shown.) 2. Configure Device A: # Enable the NTP service. system-view [DeviceA] ntp-service enable # Specify the local clock as the reference source, with the stratum level 2. [DeviceA] ntp-service refclock-master 2 3. Configure Device B: # Enable the NTP service. system-view [DeviceB] ntp-service enable # Enable NTP authentication on Device B. [DeviceB] ntp-service authentication enable # Set an authentication key, and input the key in plain text. [DeviceB] ntp-service authentication-keyid 42 authentication-mode md5 simple aNiceKey # Specify the key as a trusted key. [DeviceB] ntp-service reliable authentication-keyid 42 # Specify Device A as the NTP server of Device B, and associate the server with key 42. [DeviceB] ntp-service unicast-server 1.0.1.11 authentication-keyid 42 Before Device B can synchronize its clock to that of Device A, enable NTP authentication for Device A. 4. Configure NTP authentication on Device A: # Enable NTP authentication. [DeviceA] ntp-service authentication enable # Set an authentication key, and input the key in plain text. [DeviceA] ntp-service authentication-keyid 42 authentication-mode md5 simple aNiceKey # Specify the key as a trusted key. [DeviceA] ntp-service reliable authentication-keyid 42 5. Verify the configuration: # Display the NTP status of Device B after clock synchronization. [DeviceB] display ntp-service status Clock status: synchronized Clock stratum: 3 System peer: 1.0.1.11 Local mode: client 43
