NTP Server
To synchronize the system time on the X family device with an external time server (NTP server), select NTP as the clock source for your device. Using an NTP server, the device synchronizes time with the NTP server which allows the timing of network events on different hosts to be compared more accurately.
TIP To ensure that events times from different network entities can be meaningfully compared, configure the same NTP clients for the X family device and other network devices.
CAUTION Using external NTP servers could possibly make your device susceptible to a
The following table provides information on the NTP protocol configuration parameters.
Parameter | Description |
|
|
|
|
Duration | Interval at which the X family device will check with the time server. A |
| zero value will cause time to be checked once on boot. |
|
|
Offset | If the difference between the new time and the current time is equal to or |
| greater than the offset, the new time is accepted by the device. A zero |
| value will force time to change every time the device checks. |
|
|
Fast Sync | If this field is set to 1, the X family device is allowed to trust the NTP |
| server after the first time query. This sets the local time on the device |
| immediately, but there is a risk that the set time will be incorrect. To |
| disable this option, set this value to 0. |
|

Server Host, Port | The IP address and Port for the NTP server |
