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.
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.
The device retrieves synchronization information, either by actively requesting information or
at every poll interval.
Configure SNTP Global Settings
You can view and adjust date and time settings. SNTP stands for Simple Network Time
Protocol. As its name suggests, it is a less complicated version of Network Time Protocol,
that is a system for synchronizing the clocks of networked computer systems, primarily when
data transfer is handled through the Internet.
To configure SNTP global settings:
1.
Prepare your computer with a static IP address in the 169.254.100.0 subnet, for
example, 169.254.100.201.
2.
Connect an Ethernet cable from an Ethernet port on your computer to an Ethernet port on
the switch.
3.
Launch a web browser.
4.
Enter the IP address of the switch in the web browser address field.
The default IP address of the switch is 169.254.100.100.
The Login screen displays.
5.
Enter the user name and password.
The default admin user name is admin and the default admin password is blank, that is,
do not enter a password.
