Enabling SNTP in Unicast Mode. Like broadcast mode, configuring SNTP
for unicast mode enables SNTP. However, for Unicast operation, you must

to three unicast servers. You can use the Menu interface or the CLI to configure
one server or to replace an existing Unicast server with another. To add a

with multiple servers, see “SNTP Unicast Time Polling with Multiple SNTP
Servers” on page 21.
