SNTP: Viewing, Selecting, and Configuring

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.

3

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 9-4. 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, see “SNTP Unicast Time Polling with Multiple SNTP
Servers” on page 9-21.

Syntax

:

timesync sntp

Selects SNTP as the time synchronization method

.

sntp unicast

Configures the SNTP mode for Unicast operation

.

sntp server <ip-addr> [version]

Specifies the SNTP server. The default server version is

3.

no sntp server <

ip-addr

>

Deletes the specified SNTP server
