Can i use connexium ethernet switches as NTP server
Connexium managed switches & extended switches provide this functionality of configuring them as NTP server. The device provides two options with different levels of accuracy for synchronizing the time in your network. If you only require an accuracy in the order of milliseconds, the Simple Network Time Protocol (SNTP) provides a low-cost solution. The accuracy depends on the signal runtime.
IEEE 1588 with the Precision Time Protocol (PTP) achieves accuracies in the order of fractions of microseconds. This superior method is suitable for process control. Select the method (SNMP or PTP) that best suits your requirements.
If no reference clock is available, you have the option of entering the system time in a device and then using it like a reference clock. Refer to the enclosed for complete details.
