As shown in Figure 1-10, the local clock of Device A is set as the NTP master clock, with a clock stratum level of 2.

Device B is a WX3000 series device and uses Device A as the NTP server. Device B is set to work in client mode, while Device A works in server mode automatically.

The NTP authentication function is enabled on Device A and Device B.
