Modify the Global SNTP Settings

To modify the global SNTP settings:
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
The login window opens.
4. Enter the switch's password in the password field.
The default password is password. If you added the switch to a network on the Insight
app before and you did not yet change the password through the local browser interface,
enter your Insight network password.
The System Information page displays.
5. Select System > Management > Time > Time Configuration.
The Time Configuration page displays.
If the clock source is SNTP, the SNTP Global Configuration section displays below the
Time Configuration section.
6. Select a Client mode radio button to specify the mode of operation of the SNTP client:
• Disable. SNTP is not operational. No SNTP requests are sent from the client and no
received SNTP messages are processed.
• Unicast. SNTP operates in a point-to-point fashion. A unicast client sends a request
to a designated server at its unicast address and expects a reply from which it can
determine the time and, optionally, the round-trip delay and local clock offset relative
to the server.
• Broadcast. SNTP operates in the same manner as multicast mode but uses a local
broadcast address instead of a multicast address. The broadcast address provides a
single-subnet scope while a multicast address provides an Internet-wide scope.
The default value is Unicast.
7. In the Port field, specify the local UDP port that the SNTP client receives server packets on.
