Time Protocols
SNTP: Viewing, Selecting, and Configuring
Enabling SNTP in Broadcast Mode.
Because the switch provides an SNTP
polling interval (default: 720 seconds), you need only these two commands
for minimal SNTP broadcast configuration:
Syntax:
timesync sntp
Selects SNTP as the time synchronization method
.
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:
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
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.
