Time Protocols
SNTP: Viewing, Selecting, and Configuring
Syntax: sntp broadcast
Configures
broadcast
as the SNTP mode .
For example, suppose:
■ Time synchronization is in the factory-default configuration (TimeP
is the currently selected time synchronization method).
■ You want to:
1. View the current time synchronization.
2. Select SNTP as the time synchronization mode.
3. Enable SNTP for Broadcast mode.
4. View the SNTP configuration again to verify the configuration.
The commands and output would appear as follows:
show sntp displays the SNTP configuration and also shows that
TimeP is the currently active time synchronization mode.

show sntp again displays the SNTP configuration and shows that
SNTP is now the currently active time synchronization mode and is
configured for broadcast operation.

Figure 9-7. Example of Enabling SNTP Operation in Broadcast Mode
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, refer to “SNTP Unicast Time Polling with Multiple SNTP
Servers” on page 9-24.
Syntax: timesync sntp
Selects SNTP as the time synchronization method.
Syntax: sntp unicast
Configures the SNTP mode for Unicast operation.
