SNTP Configuration
Overview
Simple Network Time Protocol (SNTP) is currently an important method to
realize time synchronization on the Internet. SNTP adopts the client-server
mode. The server obtains its own time by receiving the GPS signals or takes
its own atomic clock as its time standard, while the client, by regularly
accessing the time service provided by the server, gets the correct time
information and regulates its own clock to synchronize with the time on the
Internet. The UDP protocol and port 123 are used for communication between the
client and the server.
SNTP Configuration Task List
SNTP settings can be divided into two parts:
one part is for the local switch to take as the SNTP server, and the other is
for the local switch to take as the SNTP client.
The local switch takes as the SNTP server:
- Setting the Grade of the SNTP Server
- Enabling the SNTP Server
The local switch takes as the SNTP client:
- Setting the IP Address of the SNTP Server
- Setting the Interval of Browsing the SNTP Server
- Disabling the SNTP Server
