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 man-in-the-middle attack. It is more secure to use an NTP server on a local, protected network.

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

 

 

Peer Host, Port
