Configure the following parameters:

SNTP Version
Primary Host
Secondary Host
The SNTP mode.
Data Options:
z None—SNTP is turned off.
z Unicast—Sends a request packet periodically to the Primary host. If
communication with the Primary host fails, the request will be sent to the
Secondary host.
z Multicast—Listen for any broadcasts from an SNTP server and then
synchronizes its internal clock to the message.
z Anycast—Sends a request packet as a broadcast on the LAN to get a
response from any SNTP server. The first response that is received is used
to synchronize its internal clock and then operates in
Unicast mode with
that SNTP server.
