Enabling SNTP in Unicast Mode. Like broadcast mode, configuring SNTP
for unicast mode enables SNTP. However, for Unicast operation, you must
also specify the IP address of at least one SNTP server. The switch allows up
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 second or third server, you must use the CLI. For more on SNTP
operation with multiple servers, see "SNTP Unicast Time Polling with Multiple
SNTP Servers" on page 9-21.
