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.
Command Purpose
configure Enter Global Configuration mode.
sntp authentication-key

• key_id— The encryption key ID, which is a number from
1–4294967295.
• key_word—The authentication key, which is a string of
up to eight characters.
sntp trusted-key key_id Specify the authentication key the SNTP server must
include in SNTP packets that it sends to the switch.
The
key_id number must be an encryption key ID defined
in the previous step.

server.
A trusted key must be configured before this command is
executed.
