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 5-6. 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 5-32.
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.
