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.

Example:

Suppose that time synchronization is in the factory-default configuration (TimeP is the currently selected time synchronization method.) Complete the following:

Procedure
  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 4: Enabling SNTP operation in Broadcast Mode
switch(config)# show sntp 1
 SNTP Configuration
  Time Sync Mode: Timep
  SNTP Mode : disabled
  Poll Interval (sec) [720] :720

switch(config)# timesync sntp

switch(config)# sntp broadcast

switch(config)# show sntp 2
 SNTP Configuration
  Time Sync Mode: Sntp
  SNTP Mode : Broadcast
  Poll Interval (sec) [720] :720

  • 1show sntp displays the SNTP configuration and also shows that TimeP is the currently

    active time synchronization mode.

  • 2show sntp again displays the SNTP configuration and shows that SNTP is now the

    currently active time synchronization mode and is configured for broadcast operation.
