• SNTP Anycast Client Mode (Client Broadcast Transmission)—Select to

information. If SNTP servers have been defined, the packets go to these
servers; otherwise, the packets are transmitted to all SNTP servers on the

reception/transmission. The Add SNTP Interface Settings page opens.

STEP 4 Click Apply to save the settings to the Running Configuration file.
Defining SNTP Authentication
SNTP clients can authenticate responses by using HMAC-MD5. An SNTP server is
associated with a key, which is used as input together with the response itself to
the MD5 function; the result of the MD5 is also included in the response packet.
The SNTP Authentication page enables configuration of the authentication keys
that are used when communicating with an SNTP server that requires
authentication.
The authentication key is created on the SNTP server in a separate process that
depends on the type of SNTP server you are using. Consult with the SNTP server
system administrator for more information.
Workflow
STEP 1 Enable authentication in the SNTP Authentication page.
STEP 2 Create a key in the SNTP Authentication page.
STEP 3 Associate this key with an SNTP server in the SNTP Unicast page.
To enable SNTP authentication and define keys:
STEP 1 Click Administration > Time Settings > SNTP Authentication. The SNTP
Authentication page opens.
STEP 2 Select SNTP Authentication to support authentication of an SNTP session
between the switch and an SNTP server.
