Configuring Sntp Authentication - HPE FlexFabric 5700 Series Network Management And Monitoring Configuration Manual

Step
2. Specify an NTP server for
the device.
To use an NTP server as the time source, make sure its clock has been synchronized. If the stratum
level of the NTP server is greater than or equal to that of the client, the client does not synchronize
with the NTP server.

Configuring SNTP authentication

SNTP authentication makes sure an SNTP client is synchronized only to an authenticated
trustworthy NTP server.
To make sure SNTP authentication can work, follow these guidelines on configuring SNTP
authentication:
•
Enable authentication on both the NTP server and the SNTP client.
•
Configure the SNTP client with the same authentication key ID and key value as the NTP server,
and specify the key as a trusted key on both the NTP server and the SNTP client. For
information about configuring NTP authentication on an NTP server, see
•
Associate the specified key with an NTP server on the SNTP client.
With authentication disabled, the SNTP client can synchronize with the NTP server regardless of
whether the NTP server is enabled with authentication.
To configure SNTP authentication on the SNTP client:
Step
1. Enter system view.
2. Enable SNTP authentication.
3. Configure an SNTP
authentication key.
4. Specify the key as a trusted
key.

multiple NTP servers.
To use authentication, you must
specify the authentication-keyid
keyid option.
