For each NTP server, you can optionally specify the NTP iburst mode for faster clock synchronization. The iburst
mode sends up ten queries within the first minute to the NTP server. (When iburst mode is not enabled, only one
query is sent within the first minute to the NTP server.) After the first minute, the iburst mode typically
synchronizes the clock so that queries need to be sent at intervals of 64 seconds or more.
In the WebUI
1. Navigate to the Configuration > Management > Clock page.
2. Under NTP Servers, click Add.
3. Enter the IP address of the NTP server.
4. Select (check) the iburst mode, if desired.
5. Click Add.
In the CLI
ntp server ipaddr [iburst]
Note: The iburst mode is a configurable option and not the default behavior for the controller, as this option is considered
“aggressive” by some public NTP servers. If an NTP server is unresponsive, the iburst mode continues to send frequent queries
until the server responds and time synchronization starts.
