General steps for running a time protocol on the switch

Using time synchronization ensures a uniform time among interoperating devices. This helps you to manage and troubleshoot switch operation by attaching meaningful time data to event and error messages.

The switch offers TimeP, SNTP (Simple Network Time Protocol), NTP, and a timesync command for changing the time protocol selection (or turning off time protocol operation).

NOTE:

Although you can create and save configurations for all time protocols without conflicts, the switch allows only one active time protocol at any time.

In the factory-default configuration, time synchronization is disabled by default.

NOTE:

Because the Aruba 2530 Switch Series does not contain an RTC (real time clock) chip, Hewlett Packard Enterprise recommends configuring one of the time synchronization protocols supported. Failure to do so could result in the switch time being reset to the factory default of 01/01/1990 00:00:00 in the case of a switch reload, software upgrade, or power cycle.
