Configuring SNTP Authentication and an SNTP Server
Beginning in Privileged EXEC mode, use the following commands to require
the SNTP client to use authentication when communicating with the SNTP
server. The commands also show how to configure an SNTP server.
Requiring authentication is optional. However, if you configure
authentication on the switch SNTP client, the SNTP server must be
configured with the same authentication information to allow time
synchronization to take place between the two devices.
