Configure an SNTP Server
SNTP assures accurate network device clock time synchronization up to the millisecond.
Time synchronization is performed by a network SNTP server. The switch operates only as
an SNTP client and cannot provide time services to other systems.
Time sources are established by strata. Strata 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.
The following is an example of strata:
• 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.
• Stratum 2 . The time source is distanced from the Stratum 1 server over a network path.
For example, a Stratum 2 server receives the time over a network link, through NTP, from
a Stratum 1 server.
Information received from SNTP servers is evaluated based on the time level and server
type.
SNTP time definitions are assessed and determined by the following time levels:
• T1 . Time that the original request was sent by the client.
• T2 . Time that the original request was received by the server.
• T3 . Time that the server sent a reply.
• T4 . Time that the client received the server's reply.
