As shown in 

, the local clock of Device A is set as the NTP master clock, with a clock 

stratum level of 2. 

z 

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.  

z 

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