SNTP Authentication on 300 Series Managed Switches
Simple Network Time Protocol (SNTP) is an adaptation of the Network Time Protocol (NTP) that is used to synchronize computer clocks on the internet. It is important for devices that are networked together to have synchronized time so they can efficiently perform real time actions with each other. To do this, an SNTP server must be added to the switch and an SNTP authentication key must be configured. An authentication key allows for a device to synchronize itself with an SNTP server.
For more information on how to add an SNTP server refer to the article Add an SNTP Server on 300 Series Managed Switches.
This article explains how to configure SNTP authentication on the 300 Series Managed Switches.
