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.

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.
The device can poll unicast server types for the server time.
Polling for unicast information is used for polling a server for which the IP address is known.
SNTP servers that were configured on the device are the only ones that are polled for
synchronization information. T1 through T4 are used to determine server time. This is the
preferred method for synchronizing device time because it is the most secure method. If this
method is selected, SNTP information is accepted only from SNTP servers defined on the
device using the SNTP Server Configuration screen.
