Configuring NTP Overview NTP is typically used in large networks to dynamically synchronize time among network devices. It guarantees higher clock accuracy than manual this Switch Series cannot operate as a reference clock. It can serve as an NTP server only after it is synchronized. • NTP supports - HP 6125G | HP 6125G & 6125G/XG Blade Switches Network Management and Mon - Page 17
• Prior to system clock synchronization between Device A and Device B, the clock of Device A is set to 10:00:00 am while that of Device B is set to 11:00:00 am. • Device B is used as the NTP time server, so Device A synchronizes to Device B. • It takes 1 second for an NTP message to travel from one - HP 6125G | HP 6125G & 6125G/XG Blade Switches Network Management and Mon - Page 18
used in environments where network management is needed. Because NTP control messages are not essential for clock synchronization, they are not described in this document. A clock synchronization message is encapsulated in a UDP message in the format shown in Figure 6.
