NTP symmetric active/passive mode configuration example Network requirements • As shown in Figure 10, Device C has a clock more accurate than Device A. Set the local clock of Device A as a reference source, with the stratum level 3. • Set the local clock Device C 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. • Configure Device C to operate in symmetric-active mode and specify Device B as the passive peer of Device C. 30
