The managed switch software supports the Simple Network Time Protocol (SNTP). You can
also set the system time manually.

SNTP assures accurate network device clock time synchronization up to the millisecond.
Time synchronization is performed by a network SNTP server. The managed switch software
operates only as an SNTP client and cannot provide time services to other systems.

Time sources are established by stratums. Stratums define the accuracy of the reference
clock. The higher the stratum (where zero is the highest), the more accurate the clock. The
device receives time from stratum 1 and above since it is itself a stratum 2 device.

device receives time from stratum 1 and above since it is itself a stratum 2 device.
The following is an example of stratums:
•
Stratum 0. A real-time clock is used as the time source, for example, a GPS system.
•
Stratum 1. A server that is directly linked to a stratum 0 time source is used. Stratum 1
time servers provide primary network time standards.
