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 page.
The device retrieves synchronization information, either by actively requesting information or
at every poll interval.
You can view and modify information for adding and modifying Simple Network Time Protocol
SNTP servers.
Add an SNTP Server
To add an SNTP server:
1. Connect your computer to the same network as the switch.
You can use a WiFi or wired connection to connect your computer to the network, or
connect directly to a switch that is off-network using an Ethernet cable.
2. Launch a web browser.
3. In the address field of your web browser, enter the IP address of the switch.
If you do not know the IP address of the switch, see Access the Switch on page 14.
The login window opens.
4. Enter the switch’s password in the Password field.
The default password is password.
The System Information page displays.
5. Select System > Management > Time > SNTP Server Configuration.
The SNTP Server Configuration page displays. The page also displays the SNTP Server
Status section.
6. From the Server Type menu, select the type of SNTP address to enter in the Address field.
The address can be either an IP address (IPv4, IPv6) or a host name (DNS). The default
value is IPv4.
7. In the Address field, specify the IP address or the host name of the SNTP server.
Unicast SNTP requests are sent to this address. If this address is a DNS host name, then
that host name is resolved into an IP address each time an SNTP request is sent to it.
8. If the UDP port on the SNTP server to which SNTP requests are sent is not the standard
port (123), specify the port number in the Port field.
The valid range is 1 to 65535. The default value is 123.
