Enabling SNTP client authentication

The command sntp authentication enables SNTP client authentication on the switch. If SNTP authentication is not enabled, SNTP packets are not authenticated.

Enabling SNTP authentication allows network devices such as switches to validate the SNTP messages received from an NTP or SNTP server before updating the network time. NTP or SNTP servers and clients must be configured with the same set of authentication keys so that the servers can authenticate the messages they send and clients (switches) can validate the received messages before updating the time.

This feature provides support for SNTP client authentication on switches, which addresses security considerations when deploying SNTP in a network.
