Configuring NTP client/server mode
Network requirements
Perform the following configurations to synchronize the time between Device B and Device A:
• As shown in Figure 25 , the local clock of Device A is to be used as a reference source, with the
stratum level of 2.
• Device B works in the client/server mode and Device A is to be used as the NTP server of Device
B.
